Abstract:

Context: Extensive and rapid continuous growth in Internet Protocol (IP) based networks and as the result of increasing dependencies on these networks makes them extremely challenging to manage and keep them running all the time. 24/7 non-stop monitoring is important to minimize the down time of the network. For this reason dependency on automated network monitoring has been increased. Objectives: There are many tools and systems available for network monitoring. This includes expensive commercial solutions to open source products. Nagios and OpenNMS are two of the most popular systems and they are considered to be close competitors. Comparison discussions about them are very common at different forums on internet. But no empirical study for comparison analysis has been done. In this thesis the comparison study between Nagios and OpenNMS was conducted. Methods: Network monitoring functionalities are listed down from literature followed by industrial interviews with the networking professionals. Then taking these functionalities as a base, to evaluate, survey studies for both systems were conducted separately and comparison analysis of the results was performed. Usability evaluation of both systems was done by conducting usability testing and comparison analysis of the results was performed. Results: Besides providing the comparison of both systems this study also can help to findout the strengths and weaknesses of both systems separately. And in the end we suggested a list of functionalities and features which might help in selection of a monitoring system and also might be helpful for improvement of the monitoring systems.

Abstract:

Rapporten syftar på att utvärdera två gratisprogram samt ett kommersiellt program för att övervaka servrar i en Windowsmiljö.

I dagsläget är det viktigt för företag att servrar och tjänster är tillgängliga dygnet runt. Ett driftavbrott kan leda till förluster i både kapital och information. Detta kan motverkas genom att övervakningsprogram varnar tekniker när fel inträffar. Genom att få reda på problem i god tid kan risken för datorhaveri förebyggas.

I undersökningen har övervakningsprogrammen utvärderats efter angivna punkter i en kravspecifikation. Utvärderingarna skedde genom att försöka få samma tjänster att övervakas i de olika programmen. Detta utfördes i en laborationsmiljö bestående av virtuella Windows-servrar.

Resultatet visar att gratisprogrammen kan uppfylla många av kraven i kravspecifikationen. Skillnaden med kommersiella alternativet som företaget använder är att all konfiguration sker i ett webbgränssnitt.

Abstract:

Rapporten tar upp en kartläggning av nätverksövervakningssystem (NMS) som används för att övervaka nätverkstjänster och noder på ett nätverk. De egenskaper för NMS som utvärderas är vilket stöd systemen har för att övervaka ett flertal tjänster, hur god prestandan är för varje system samt hur god användbarheten i gränssnittet är. Resultatet visar att Nagios, OpenNMS samt Argus hade stöd för samtliga tjänster medan Munin inte hade stöd för nätverksenheter och Cacti endast stöd att övervaka SNMP. Det visar även att Nagios och OpenNMS generellt hade möjlighet att larma vid fler händelser samt att dessa två system var markant snabbare än Cacti och Munin. Användbarheten visade relativt stor skillnad i olika system. OpenNMS hade högst totalpoäng, men Nagios presterade något bättre i vad Sundström (2005) kallar för interaktion. Munin och Argus fick samma resultat med låg funktionalitet och högre struktur medan Cacti hade god funktionalitet och interaktion men väldigt låg struktur.

Abstract:

Denna uppsats undersöker möjligheten att använda ett nätverksövervakningssystem för att även övervaka maskindrivna processer. Kan man baka ihop övervakningen av den maskinella processen och datorn som styr maskinen i ett och samma system? Detta genomförs genom att identifiera och implementera ett lämpligt övervakningssystem i en befintlig maskinell laborationsmiljö. Arbetet utvärderas därefter enligt ett antal felscenarion och även utifrån ett systemadministratörsperspektiv. Intervjuer med praktiker inom industribranchen utförs också för att dra ytterligare slutsatser.

Abstract:

The themes of this thesis are that international trade and foreign direct investment (FDI) are closely related and that they have varying impacts on economic growth in countries at different stages of development. The thesis consists of three empirical studies. The first one examines the causal relationship between FDI and trade in China. The empirical study is based on a panel of bilateral data for China and 19 home countries/regions over the period 1984-98. The specific feature of the study is that econometric techniques designed specially for panel data are applied to test for unit roots and causality. The results indicate a virtuous procedure of development for China. The growth of China’s imports causes growth in inward FDI from a home country/region, which in turn causes the growth of exports from China to the home country/region. The growth of exports causes the growth of imports. This virtuous procedure is the result of China’s policy of opening to the outside world. China has been encouraging export-oriented FDI and reducing trade barriers. Such policy instruments should be further encouraged in order to enhance economic growth. In the second study, an extended gravity model is constructed to identify the main causes of recent trade growth in OECD countries. The specific features include (a) the explicit introduction of R&D and FDI as two important explanatory variables into an augmented gravity equation; (b) the adoption of a panel data approach, and (c) the careful treatment of endogeneity. The main findings are that the levels and similarities of market size, domestic R&D stock and inward FDI stock are positively related to the volume of bilateral trade, while the geographical distance, exchange rate and relative factor endowments, has a negative impact. These findings lend support to new trade, FDI and economic growth theories. The third study evaluates the impact of openness on growth in different country groups.

Abstract:

Economic integration between major powers has long been viewed as a force for international stability. The intuitive logic is appealing: states that are trading with and investing in each other stand to lose if that commerce is jeopardized by conflict. Yet there are sound reasons for supposing that such deepening economic integration can also shift the balance of power between major states, by causing follower economies – states that are not among the most developed in the international system – to grow faster than leading economies, and economic size and development are what underpin national material capabilities. Moreover, a rich body of theory and history suggests that such shifts in the balance of power make interstate war more likely. This dissertation argues, therefore, that economic integration can actually be a potent cause of security competition and war. A theoretical framework that unites economic theory on the differential growth impact of trade, financial flows, and technology diffusion with realist arguments on the conflict implications of polarity shifts and dynamic power differentials is constructed. It is then explored using evidence from three key historical cases: the rise of the Dutch Republic during the 1581-1648 period, the relative decline of the United Kingdom and the relative rise of other great powers between 1870 and 1914, and the differential growth rates and corresponding tensions of 1945-89. Certain scope conditions and qualifications notwithstanding, the empirical evidence supports the theoretical framework. As such, the argument that deepening economic integration raises the mutual cost of fighting and thereby makes conflict less likely is not directly refuted, but an important countervailing mechanism is found to be at work. Such a finding has implications for debates over the security implications of economic globalization, the foundations of realist theory, and the causes and potential consequences of the rise of new powers today.

Abstract:

The present thesis tries to argue the importance of non monetary factors in explaining real exchange rate volatility. The main interest is on the effect of trade openness on real effec-tive exchange rate (REER) volatility. Based on theoretical studies I test the existence of a negative relationship between total trade share of an economy and the volatility of REER. Empirical evidence on a panel of 11 CEE and Baltic Countries for the 1995-2006 period confirms the relationship. The conclusion is that for these specific countries a large part of variation of the real exchange rate can be explained by openness of the respective economy to trade.

Foster, Neil. "North-South trade, openness and growth." Thesis, University of Nottingham, 2001. http://eprints.nottingham.ac.uk/12856/.

Abstract:

It has long been thought that openness to international trade can be beneficial to a country in terms of growth, and that trade liberalisation can assist in enhancing countries growth rates. For a long time such arguments were based on static theories, in which trade raises the level of income, but not the long-run growth rate. Recently, models have emerged that show how countries can increase their long-run growth rates through trade. Trade can affect growth through a number of channels. For developing countries however, the primary benefit that trade provides is likely to be access to the technology of more advanced countries. This study examines various aspects of the relationship between openness to trade and economic growth in developing countries. The study concentrates on North-South trade, since it is expected that imports from the North enhance growth by allowing access to more advanced knowledge and technology. It is shown that trade with the North can benefit countries in the South in terms of higher growth, through the importation of Northern goods. Evidence is also found to suggest that trade has a role in transferring to the South the benefits of Research and Development (R&D) conducted in the North, although these results tend not to be robust. The second part of the study examines the impact of trade liberalisation on openness and growth. It is found that trade liberalisation has tended to lower openness to imports from the North, at least in the short-run. The results suggest the possibility of a J-curve effect whereby openness initially falls, but then recovers somewhat. In the long-run we may expect openness to rise following liberalisation, but this cannot be shown in our dataset. The relationship between liberalisation and growth is also found to follow a J-curve, with liberalisation initially leading to a reduction in growth, but in the long-run increasing growth in per capita income.

Abstract:

Malgré le consensus qui prévaut sur les effets de la politique monétaire, à court et moyen termes sur l’économie réelle, et à long terme sur l’inflation, le poids relatif des canaux de transmission de politique monétaire reste en débat. Aujourd’hui les derniers résultats de la littérature sur la politique monétaire et les évolutions importantes constatées dans la structure financière et économique des pays du monde, conduisent à de nouvelles idées et interrogations sur l’importance du rôle de la politique monétaire. L’ouverture croissante des économies nationales pose en effet de nouveaux défis aux mécanismes de transmission de politique monétaire existants. Cependant, les chercheurs ont encore peu exploité cette nouvelle dimension et la littérature actuelle n’explique qu’une partie de la relation mondialisation/inflation. Cette thèse vise à apporter une contribution à ce débat. En débutant par une analyse des mécanismes de transmission monétaire, des canaux et des décalages correspondants, nous développons un modèle théorique qui explique les évolutions et les défis de la politique monétaire dans un contexte de mondialisation. Nous utilisons ensuite une base de données concernant un large échantillon de pays pour calculer dans un premier temps la production potentielle et l’écart de production pour l’ensemble de l’échantillon. Puis, dans un second temps, à l’aide d’estimations en données de panel fondées sur une équation de la courbe de Philips, nous étudions les impacts de la mondialisation sur l’inflation pour l’ensemble des économies du panel mais aussi pour des sous-ensembles régionaux
Despite the prevalent consensus on the short to medium-run effects of monetary policy shocks on the real economy and long-run effects on inflation; the relative importance of the channels of monetary transmission mechanism (MTM) still remains open to debate. In this regard, recent findings of the monetary literature and the important developments in the economic and financial structure of the economies on the whole invoke new insights and important questions on the relevancy of monetary policy. The new era of increased openness has also started posing new challenges to the existing monetary transmission mechanism and the policy effects thereof. However, this area has yet not been explored on merit by the researchers, and the existing literature explains only a small part of this globalization –inflation puzzle. Therefore, this thesis aims to make a contribution to this debate. Starting with the analysis of monetary transmission the corresponding channels and the lags we develop a theoretical model to explain the developments and challenges to the monetary policy in the current scenario of increased globalization. The succeeding section deals with the data of a large set of economies, where in the first instance we compute the potential output and subsequently the output gap for the whole sample. Going ahead we conduct panel estimation using Phillips curve equation for our sample to investigate the globalization impacts on the economies on the whole and in parts based on the regional and economic groups

Abstract:

Multi-core computer systems have widely been accepted as the future standard in computer architecture. Many simple processing cores bundled together on a single die have been shown more successful in terms of power consumption and execution performance compared to previous large and heavily pipelined uni-core systems. And as the chip dimensions decrease, temperature effects starts to become prominent. Elevated temperature gradients and hotspot on processors put an upper limit on both the execution performance and the life-time of the devices, leading to failures, slowdown and eventually malfunction. Most work involved in software-based temperature management in multi-core systems have been in the kernel-space, hidden from the user. This work hopes to change this, and show that it is possible to make user level schedulers account for temperature changes occurring in the system. OpenMP is the current standard in parallel programming and was used to implement a scheduling policy that uses hardware feedback to effectively try to eliminate elevated temperatures on the chip. The system itself was simulated and modeled using well-established simulators and models. The results were promising, showing a decrease in time spent above the critical temperature with up to 140 times in some benchmarks and a decreased power consumption in all the benchmarks as compared to the Cilk and Breadth-first scheduler. This alone should encourage to more research in this area, and hopefully give rise to a future standard of user level temperature control in parallel based schedulers.

Abstract:

In questa tesi introduciamo la polyhedral compilation, una moltitudine di tecniche volte a rappresentare programmi, specialmente quelli che coinvolgono cicli innestati e vettori, rappresentandoli attraverso poliedri parametrici e sfruttando alcune trasformazioni su di essi per analizzare e ottimizzare automaticamente i programmi dati. In particolare, descriviamo la nostra implementazione di un polyhedral compiler: OPoly. OPoly è un'applicazione realizzata in Python in grado di parallelizzare automaticamente cicli innestati che possono essere espressi attraverso un insieme di equazioni ricorsive uniformi. OPoly analizza dei cicli innestati scritti in pseudolinguaggio e genera del codice sorgente parallelizzabile scritto in C e compreso di direttive OpenMP, che può rimpiazzare l'implementazione seriale originale, senza cambiarne il significato. OPoly sfrutta il linguaggio di modellazione per programmazione a vincoli MiniZinc per modellare il problemi di ottimizzazione dell'approccio poliedrico, che sono cruciali per trovare la trasformazione migliore possibile dal ciclo originale a quello parallelizzabile. Descriviamo l'architettura di OPoly e diamo alcune soluzioni pratiche a problemi che sorgono implementando un polyhedral compiler. Infine, compariamo le prestazioni del codice parallelizzabile generato da OPoly con quelle della relativa implementazione originale, studiando il caso di un noto algoritmo scientifico.

Abstract:

The main purpose of the present study was to explore the effects of characteristics of information given in a job advertisement (amount of information and the specificity of the information) on the potential applicants&rsquo
willingness to apply to the job opening with the mediating roles of credibility of and satisfaction from the information, and attraction to the organization. In addition to that, the factors affecting the decision of the applicants to apply for the job posted such as application modes (internet, by hand in the same city the applicant lives, by hand in a different city than the applicant lives), different selection methods (interview, personality test, knowledge test), and personality characteristics (goal orientation and self-efficacy) were investigated. The study was conducted in three phases. In the first phase, one hundred and seven Middle East Technical University (METU) students were used to decide between two alternatives of goal orientation and two self-efficacy scales, which were translated into Turkish and adapted for the current study, to be used in the main study by determining the validity and reliabilities of the scales. The second phase was the manipulation check, conducted to test the clarity and meaningfulness of the newly developed job advertisements and questions related to the research hypotheses. Thirty-two METU students were used for the second phase. The final phase was the main study. One hundred and fifty four METU students from Electrical and Electronics Department were used to examine the hypotheses of the study.The students were randomly assigned to the three different versions of job advertisement. Additionally, a questionnaire package was given to each participant. The results supported most of the main hypotheses and the proposed model except for the mediating effect of satisfaction. Advertisement type affected the willingness to apply to the job of potential applicant and this relation was mediated by credibility and credibility was mediated by attractiveness to the organization. A main effect of application mode was found for change in application decision, but no interaction was found between application mode and different attraction levels. Goal orientation found to be affecting applicants&rsquo
decision change for different selection methods. Self-efficacy failed to predict decision change for application for different selection methods. Results are discussed along with the strengths and limitations of the study and suggestions for future research.

Leone, Matthew J. (Matthew Joseph). "The shape of openness : Bakhtin, Lawrence, laughter." Thesis, McGill University, 1992. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=39750.

Full text

Abstract:

How is Bakhtin's conception of novelistic openness distinct from modernist-dialectical irresolution or open-endedness? Is Women in Love a Bakhtinian "open totality"? How is dialogic openness (as opposed to modernist indeterminacy) a "form-shaping ideology" of comic interrogation?
This study tests whether dialogism illuminates the shape of openness in Lawrence. As philosophers of potentiality, both Bakhtin and Lawrence explore the dialogic "between" as a state of being and a condition of meaningful fiction. Dialogism informs Women in Love. It achieves a polyphonic openness which Lawrence in his later fictions cannot sustain. Subsequently, univocal, simplifying organizations supervene. Dialogic process collapses into a stenographic report upon a completed dialogue, over which the travel writer, the poet or the messianic martyr preside.
Nevertheless, the old openness can be discerned in the ambivalent laughter of The Captain's Doll, St. Mawr or "The Man Who Loved Islands." In these retrospective variations on earlier themes, laughing openness of vision takes new, "unfinalizable" shapes.

Abstract:

This project investigates the heat flow from the rock into ventilating airways by studying various parameters. Two approaches have been used: laboratory measurement of thermal properties to study their variation, and analytic and numerical models to study the effect of these variations on the heat flow. Access to a heat-flux system and special treatment of contact resistance has provided the opportunity to study thermal conductivity as a function of moisture contained in rock specimens. For porous sandstone, tuff, and concretes, thermal conductivity can double when the specimens are soaked; the functional dependence of conductivity on moisture for the first two cases is definitely non-linear. Five previous models for conductivity as a function of porosity are shown not to explain this new phenomenon. A preliminary finite element model is proposed which explains the key features. Other variations of conductivity with applied pressure, location, constituents, weathering or other damage, and anisotropy have been measured. In the second phase of the research, analytical and numerical methods have been employed to consider the effects of the variation in the thermal properties plus the use of insulation on the heat flow from the rock into the ventilated and cooled airways. Temperature measurements taken in drill holes at a local mine provide confirmation for some of the models. Results have been provided in a sensitivity analysis mode so that engineers working on other projects can see which parameters would require more detailed consideration. The thermal conductivity of the rock close to the airways is a key factor in affecting heat loads. Dewatering and the use of insulation, such as lightweight foamed shotcretes, are recommended.

Goble, Keryn Sheree. "Height of Flames Projecting from Compartment Openings." Thesis, University of Canterbury. Civil and Natural Resources Engineering, 2007. http://hdl.handle.net/10092/1580.

Full text

Abstract:

External flaming from buildings occurs as a result of a large amount of fuel being available in the room of fire origin in comparison to the amount of ventilation provided. The size of the openings in a compartment affects the amount of oxygen available within the fire room, and hence the amount of combustion that can take place inside. Excess fuel that is not burnt within the room flows out of the opening and combusts upon reaching the oxygen in the air outside. It is in this situation that flames are seen projecting out of the window. Flames projecting from openings pose the threat of fire spread from the room of fire origin. This threat increases with the size of the flames. Thus a dependable method for predicting the size of flames projecting from openings is required. This research addresses the issue of predicting flame heights projecting from openings, based on the heat release rate of a fire. The results are based on laboratory experiments and are presented in non-dimensional form, allowing application to scenarios that have not been specifically tested. This work supports the findings of other researchers, with appropriate adjustments made to compensate for differing experimental approaches. This indicates that the relationships established between the non-dimensional heat release rate and flame height are formed from a sound underlying principle. An empirical relationship between the non-dimensional flame height and heat release rate of a fire is presented in a simplified format to enable ease of use. The temperatures attained, and other observations from the compartment fire experiments are also presented and discussed. These were found to have dependence on a number of factors, with relationships varying between the individual experiments. The widely-used computational fluid dynamics model Fire Dynamics Simulator, Version 4 (FDS), was found to currently be unreliable in modelling the experimental scenarios. The results obtained were unrealistic and bore minimal resemblance to the experimental results, with extensive computational simulation time. The ability of the programme to model the compartment fire scenario requires further investigation to determine whether a finer grid resolution may improve results, or whether it is simply not able to model combustion processes involved at this stage.

Full text

Abstract:

The thesis deals with the axial strength of axially and eccentrically loaded concrete walls with cut-out openings strengthened by fiber-reinforced polymers (FRPs).Background: Functional modifications of concrete structures are common because existing structures must often be adapted to comply with current living standards. Such modifications may include the addition of new windows or doors and paths for ventilation and heating systems, all of which require openings to be cut into structural walls. These openings are a source of weakness and can size dependently reduce the structures’ stiffness and load-bearing capacity, thus, requiring the element to be repaired.Aim and objectives: The main aim of this project was to develop a toolbox containing solutions for strengthening concrete walls with existing or newly created openings using FRP materials. The two immediate objectives sought are: (1) An assessment of the research level on concrete walls with and without openings; (2) An experimental and numerical investigation of the structural behavior of the FRP strengthened walls with openings.Methods of investigation: The experimental program was defined by reviewing therelevant tests performed to date. The literature review revealed research gaps that the current study aims to fill. Moreover, preliminary nonlinear finite element analyses were performed prior to the experimental program in order to gain insight into the structural behavior of these elements. Nine specimens designed to represent typical wall panels in residential buildings, at half-scale, were constructed for testing to failure. The two types of openings examined comprised symmetric halfscaled single door-type openings, and symmetric half scaled double door-type openings. The test matrix was divided into three stages, namely: (1) Reference specimens, (2) Pre-cracked specimens strengthened by FRP and (3) Un-cracked specimens strengthened by FRP. The strengthening method used was FRP confinement with the aid of mechanical anchorages.Results: The results indicate that the 25% and 50% reductions in cross-sectional area of the solid wall caused by introducing the small opening and large opening reduced its load carrying capacity by nearly 36% and 50%, respectively. The application of the FRP confinement increases the capacity and the stiffness of the specimens with cut-out openings. The axial strengths were between 85 94.8% and 56.5-63.4% for specimens having a small and large opening, respectively, of that of a solid wall.Conclusion: The FRP-confinement together with the mechanical anchorages was able to partly restore the capacity of a solid wall. Better results might have been possible if longitudinal FRP strips or bi-directional fibers were used. The effects of steel anchorages were not investigated and it is believed that they might have had positive influences. However, the optimal distance between the anchors should be further investigated. Moreover, the influence of the prestressing force of the anchorages may also be an important parameter that has led to an increase in capacity.

Abstract:

This research entails an empirical examination of the determinants of trade openness in Africa and the determinants of bilateral trade flows between Africa and the BRIC and OECD member countries. Besides, the study examines the impacts of trade openness on the economic growth in Africa. Before all this is done, the study surveys the updated empirical data on the African economy and trade to give a state of the art on the economic development processes in the African continent. Recognising the role of international trade in the global economic growth and considering the marginalisation of Africa in the world trade, this study highlighting important factors that are relevant for policy makers in the African countries to consider in order to boost-up their trade levels. It is also an attempt to empirically examine and provide explanations on the relatively lower trade levels that these countries have been experiencing ever since their political independence. The study has been done with panel data analysis methods in order to capture the relationships between the variables of interest over an extended time periods and disentangle the time invariant country specific effects that are very relevant particularly in examining bilateral trade flows. Econometric estimations of the coefficients for the regressors were made through the application of either random effects or fixed effects models, a selection of which is based on Hausman test. Where necessary the study has made use of instrumental variable estimation techniques like the 2SLS, Hausman Taylor and System GMM. Among others, this research contributes to the existing literature by examining the importance of private sector and the role of the ever- increasing mobile phone subscriptions in the African countries, in enhancing intra African bilateral trade flows. The facilitation of the private sector through provision of credits can enhance intra and inter African trade as well as boosting up the efforts to diversify African exports composition and export market destinations.

Abstract:

In today’s society of increased globalization and digitalization openness has become a buzzword. This raises questions about what we mean by openness and how it is interpreted in various contexts. This thesis has two aims; to explore how openness is interpreted in planning, politics and political decision-making, and to develop an analytical tool to assess openness in different contexts. A new institutional theory framework that centers on the interplay between institutions and actors has been used, and three empirical case studies in a Swedish context were conducted to analyze how openness is interpreted in planning in metropolitan regions, in politics through the political parties and in political decision-making in the Stockholm region. The research concludes that openness in planning, politics and political decision-making is interpreted along two inter-linked narrative lines: ’openness to people’ and ’openness to knowledge, information and ideas’. It was more common to talk about peoples’ accessibility to public services and participation in different parts of society (’openness to people’) than to talk about issues of transparency and ’openness to knowledge, information and ideas’. The institutional framework shows how openness is interpreted at different institutional levels. To what degree openness is expressed at different institutional levels vary by context. In planning for instance, openness is mainly interpreted in terms of governance, whereas in politics and political decision-making, openness is interpreted in an inter-play between culture and norms, institutions, governance and practice. The institutional framework complementary context-specific theories and elaborated into an analytical model, was found useful to explain what mechanisms are at play when dealing with openness in planning, politics and political decision-making, and can be applicable in future research of openness in other geographical or organizational contexts.

Abstract:

Future multi- and many- core processors are likely to have tens of cores arranged in a tiled architecture where each tile will house a processing core and a bank of the shared last-level cache. The physical distribution of tiles on the processor die gives rise to a Distributed Shared Cache (DSC) architecture where cache access latencies are non-uniform and depend on the physical distance between core and cache bank. In order to maximize cache capacity and favor design simplicity, the address space on a tiled processor is likely to be divided and mapped either statically or dynamically on to the distributed last-level cache such that each cache bank homes certain cache blocks. Given this architecture, an efficient OpenMP 3.0 task scheduler can minimize miss latencies by scheduling tasks on tiles whichare physically closer to the cache banks which home task-relevant data. This master thesis work deals with the design and implementation of a locality-aware user-level runtime OpenMP 3.0 task scheduler for a simulated tiled multicore architecture. Guided by programmer hints, the scheduler extracts locality information pertaining to the data referenced by a task and schedules the task accordingly on the core closest to the L2 slice homing the largest amount of data. Initial results of performance comparison against a work-first randomized work-stealing cilk-like scheduler and a breadth-first randomized work-stealing scheduler have revealed problems with the locality-aware scheduler and have created ground for deeper exploration in the areas of programmer locality characterization and feedback-based extraction of locality information.

Abstract:

With the rapid rise of the popularity of online social networks (OSNs) in recent years, we have seen tremendous growth in the number of available OSNs. With newer OSNs attempting to draw users in by focussing on specific services or themes, it is becoming clearer that OSNs do not compete on the quality of their technology but rather the number of active users. This leads to vendor lock-in, which creates problems for users managing multiple OSNs or wanting to switch OSNs. Third party applications are often written to alleviate these problems but often find it difficult to deal with the differences between OSNs. These problems are made worse as we argue that a user will inevitably switch between many OSNs in his or her lifetime due to OSNs being incredibly fashionable things whose lifespan is dependent on social trends. Thus, these applications often only support a limited number of OSNs. This thesis examines how it is possible to help developers write apps that run against multiple OSNs. It describes the need for and presents a novel set of abstractions for apps to use to interface with OSNs. These abstractions are highly expressive, future proof, and removes the need for an app to know which OSNs it is running against. Two evaluations were done to determine the strength of these abstractions. The first evaluation analyzed the expressiveness of the abstractions while the latter analyzed the feasibility of the abstractions. The contributions of this thesis are a first step to better understanding how OSNs can be described at a high level.

Abstract:

Nowadays, applications from dissimilar domains, such as high-performance computing and high-integrity systems, require levels of performance that can only be achieved by means of sophisticated heterogeneous architectures. However, the complex nature of such architectures hinders the production of efficient code at acceptable levels of time and cost. Moreover, the need for exploiting parallelism adds complications of its own (e.g., deadlocks, race conditions,...). In this context, compiler analysis is fundamental for optimizing parallel programs. There is however a trade-off between complexity and profit: low complexity analyses (e.g., reaching definitions) provide information that may be insufficient for many relevant transformations, and complex analyses based on mathematical representations (e.g., polyhedral model) give accurate results at a high computational cost. A range of parallel programming models providing different levels of programmability, performance and portability enable the exploitation of current architectures. However, OpenMP has proved many advantages over its competitors: 1) it delivers levels of performance comparable to highly tunable models such as CUDA and MPI, and better robustness than low level libraries such as Pthreads; 2) the extensions included in the latest specification meet the characteristics of current heterogeneous architectures (i.e., the coupling of a host processor to one or more accelerators, and the capability of expressing fine-grained, both structured and unstructured, and highly-dynamic task parallelism); 3) OpenMP is widely implemented by several chip (e.g., Kalray MPPA, Intel) and compiler (e.g., GNU, Intel) vendors; and 4) although currently the model lacks resiliency and reliability mechanisms, many works, including this thesis, pursue their introduction in the specification. This thesis addresses the study of compiler analysis techniques for OpenMP with two main purposes: 1) enhance the programmability and reliability of OpenMP, and 2) prove OpenMP as a suitable model to exploit parallelism in safety-critical domains. Particularly, the thesis focuses on the tasking model because it offers the flexibility to tackle the parallelization of algorithms with load imbalance, recursiveness and uncountable loop based kernels. Additionally, current works have proved the time-predictability of this model, shortening the distance towards its introduction in safety-critical domains. To enable the analysis of applications using the OpenMP tasking model, the first contribution of this thesis is the extension of a set of classic compiler techniques with support for OpenMP. As a basis for including reliability mechanisms, the second contribution consists of the development of a series of algorithms to statically detect situations involving OpenMP tasks, which may lead to a loss of performance, non-deterministic results or run-time failures. A well-known problem of parallel processing related to compilers is the static scheduling of a program represented by a directed graph. Although the literature is extensive in static scheduling techniques, the work related to the generation of the task graph at compile-time is very scant. Compilers are limited by the knowledge they can extract, which depends on the application and the programming model. The third contribution of this thesis is the generation of a predicated task dependency graph for OpenMP that can be interpreted by the runtime in such a way that the cost of solving dependences is reduced to the minimum. With the previous contributions as a basis for determining the functional safety of OpenMP, the final contribution of this thesis is the adaptation of OpenMP to the safety-critical domain considering two directions: 1) indicating how OpenMP can be safely used in such a domain, and 2) integrating OpenMP into Ada, a language widely used in the safety-critical domain.
Actualment, aplicacions de dominis diversos com la computació d'altes prestacions i els sistemes d'alta integritat, requereixen nivells de rendiment assolibles només mitjançant arquitectures heterogènies sofisticades. No obstant, la natura complexa d'aquestes dificulta la producció de codi eficient en un temps i cost acceptables. A més, la necessitat d’explotar paral·lelisme introdueix complicacions en sí mateixa (p. ex. bloqueig mutu, condicions de carrera,...). En aquest context, l'anàlisi de compiladors és fonamental per optimitzar programes paral·lels. Existeix però un equilibri entre complexitat i beneficis: la informació obtinguda amb anàlisis simples (p. ex. definicions abastables) pot ser insuficient per moltes transformacions rellevants, i anàlisis complexos basats en models matemàtics (p. ex. model polièdric) faciliten resultats acurats a un alt cost computacional. Existeixen molts models de programació paral·lela que proporcionen diferents nivells de programabilitat, rendiment i portabilitat per l'explotació de les arquitectures actuals. En aquest marc, OpenMP ha demostrat molts avantatges respecte dels seus competidors: 1) el seu nivell de rendiment és comparable a models molt ajustables com CUDA i MPI, i proporciona més robustesa que llibreries de baix nivell com Pthreads; 2) les extensions que inclou la darrera especificació satisfan les característiques de les actuals arquitectures heterogènies (és a dir, l’acoblament d’un processador principal i un o més acceleradors, i la capacitat d'expressar paral·lelisme de tasques de gra fi, ja sigui estructurat o sense estructura; 3) OpenMP és àmpliament implementat per venedors de xips (p. ex. Kalray MPPA, Intel) i compiladors (p. ex. GNU, Intel); i 4) tot i que el model actual manca de mecanismes de resiliència i fiabilitat, molts treballs, incloent aquesta tesi, busquen la seva introducció a l'especificació. Aquesta tesi adreça l'estudi de tècniques d’anàlisi de compiladors amb dos objectius: 1) millorar la programabilitat i la fiabilitat de OpenMP, i 2) provar que OpenMP és un model adequat per explotar paral·lelisme en sistemes crítics. En particular, la tesi es centra en el model de tasques per què aquest ofereix la flexibilitat per abordar aplicacions amb problemes de balanceig de càrrega, recursivitat i bucles incomptables. A més, treballs recents han provat la predictibilitat en qüestió de temps del model, escurçant la distància cap a la seva introducció en sistemes crítics. Per a poder analitzar aplicacions que utilitzen el model de tasques d’OpenMP, la primera contribució d’aquesta tesi consisteix en l’extensió d'un conjunt de tècniques clàssiques de compilació per suportar OpenMP. Com a base per incloure mecanismes de fiabilitat, la segona contribució consisteix en el desenvolupament duna sèrie d'algorismes per detectar de forma estàtica situacions que involucren tasques d’OpenMP, i que poden conduir a una pèrdua de rendiment, resultats no deterministes, o fallades en temps d’execució. Un problema ben conegut del processament paral·lel relacionat amb els compiladors és la planificació estàtica d’un programa representat mitjançant un graf dirigit. Tot i que la literatura sobre planificació estàtica és extensa, aquella relacionada amb la generació del graf en temps de compilació és molt escassa. Els compiladors estan limitats pel coneixement que poden extreure, que depèn de l’aplicació i del model de programació. La tercera contribució de la tesi és la generació d’un graf de dependències enriquit que pot ser interpretat pel sistema en temps d’execució de manera que el cost de resoldre les dependències sigui mínim. Amb les anteriors contribucions com a base per a determinar la seguretat funcional de OpenMP, la darrera contribució de la tesi consisteix en adaptar OpenMP a sistemes crítics, explorant dues direccions: 1) indicar com OpenMP es pot utilitzar de forma segura en un domini com, i 2) integrar OpenMP en Ada, un llenguatge molt utilitzat en el domini de seguretat.

Abstract:

Clusters, i.e., several computers interconnected with acommunication network, provide a cost efficient way to achievehigh performance. Messages are the natural way of communicationin this kind of systems. However, it is widely argued thatusing a shared memory programming model reduces the programmingeffort. Hence it is interestingto investigate systems thatprovide shared memory on clusters.

This thesis describes some performance aspects of providingsuch a shared memory using software. The systems that provide ashared memory in software are commonly called softwaredistributed shared memory systems, software DSM systems. Thethesis consists of seven papers that each describe differentaspects of software DSM systems.

One of the main performance bottlenecks is the communicationnetwork and three papers in the thesis investigates thisbottleneck. One paper analyzes the traffic sent on the networkwhen applications are executed. In another paper a latencyhiding technique is described and evaluated that substantiallyincreases the performance of iterative applications, i.e.,applications with loops. The last paper investigates the use ofpriorities to reduce the latency of certain messages used bythe software DSM system.

One paper is devoted to discussing how a portable softwareDSM system should be designed and this paper forms the basisfor the remaining three papers. These papers also present acompiler and run-time library for OpenMP which is a recentindustry shared memory programming model. The compiler and therun-time library were developed as part of the thesis. One ofthe three papers describes a prototype system for runningOpenMP applications on clusters. The second presents thecompiler and compares the performance of applications compiledwith the compiler with that of the applications compiled with acommercial compiler. The last paper describes the OpenMPrun-time library.

Abstract:

A exploração eficiente do paralelismo no nível de threads tem sido um desafio para os desenvolvedores de softwares. Como muitas aplicações não escalam com o número de núcleos, aumentar cegamente o número de threads pode não produzir os melhores resultados em desempenho ou energia. No entanto, a tarefa de escolher corretamente o número ideal de threads não é simples: muitas variáveis estão envolvidas (por exemplo, saturação do barramento off-chip e sobrecarga de sincronização de dados), que mudam de acordo com diferentes aspectos do sistema (por exemplo, conjunto de entrada, micro-arquitetura) e mesmo durante a execução da aplicação. Para abordar esse complexo cenário, esta tese apresenta Aurora. Ela é capaz de encontrar automaticamente, em tempo de execução e com o mínimo de sobrecarga, o número ideal de threads para cada região paralela da aplicação e se readaptar nos casos em que o comportamento de uma região muda durante a execução. Aurora trabalha com o OpenMP e é completamente transparente tanto para o programador quanto para o usuário final: dado um binário de uma aplicação OpenMP, Aurora o otimiza sem nenhuma transformação ou recompilação de código. Através da execução de quinze benchmarks conhecidos em quatro processadores multi-core, mostramos que Aurora melhora o trade-off entre desempenho e energia em até: 98% sobre a execução padrão do OpenMP; 86% sobre o recurso interno do OpenMP que ajusta dinamicamente o número de threads; e 91% quando comparado a uma emulação do feedback-driven threading.
Efficiently exploiting thread-level parallelism has been challenging for software developers. As many parallel applications do not scale with the number of cores, blindly increasing the number of threads may not produce the best results in performance or energy. However, the task of rightly choosing the ideal amount of threads is not straightforward: many variables are involved (e.g. off-chip bus saturation and overhead of datasynchronization), which will change according to different aspects of the system at hand (e.g., input set, micro-architecture) and even during execution. To address this complex scenario, this thesis presents Aurora. It is capable of automatically finding, at run-time and with minimum overhead, the optimal number of threads for each parallel region of the application and re-adapt in cases the behavior of a region changes during execution. Aurora works with OpenMP and is completely transparent to both designer and end-user: given an OpenMP application binary, Aurora optimizes it without any code transformation or recompilation. By executing fifteen well-known benchmarks on four multi-core processors, Aurora improves the trade-off between performance and energy by up to: 98% over the standard OpenMP execution; 86% over the built-in feature of OpenMP that dynamically adjusts the number of threads; and 91% over a feedback-driven threading emulation.

Abstract:

Parallelisation is becoming more and more important as the single core performance increase is stagnating while the amount of cores is increasing with every new generation of hardware. The traditional approach of manual parallelisation has an alternative in parallel frameworks, such as OpenMP, which can simplify the creation of parallel code. Optimising this code can, however, be cumbersome and difficult. Automating the optimisation or tuning of parallel code and computations is a very interesting alternative to manually optimising algorithms and programs. Previous work has shown that intricate systems can effectively autotune parallel programs with potentially the same effectiveness as human experts. This study suggests using an approach with the main algorithm used inspired from the congestion control algorithms from computer networks, namely AIMD. By applying the algorithm on top of an OpenMP program the parallel parameters such as grain size can be controlled. Thee simplied algorithm is shown to be able to achieve a 19% speedup compared to a naive static parallel implementation

Abstract:

Open innovation has been widely debated in management literature. However, little attention has been given to how small and medium sized enterprises manage to open up their innovation process. Consequently, various questions remain unanswered. In particular, we want to shed light on the following issue: how small and medium-sized enterprises manage organizational changes in their journey from closed to open innovation. A literature review examines how small and medium-sized enterprises open up their innovation process based on nine perspectives. Then, the reference framework addresses the organizational changes embedded in evolving from closed to open innovation. In this sense, we use acknowledged concepts on organizational change research to carry out an in depth-case study on a small and medium-sized enterprise evolving in the sports equipment industry. The results demonstrate that, in its journey from closed to open innovation, the small and medium-sized enterprise has had to stimulate and to manage changes to four company’s dimensions i.e. corporate culture, networking, organizational structure, and knowledge management systems. The paper concludes by highlighting the diverse organizational changes undertaken by the company on these four dimensions. Based on this paper’s conclusion, managerial implications and discussion for future research are drawn.

Abstract:

This thesis presents ground control best practices in weak rock environments including an augmentation to the existing Span Design curve by adding 463 case histories of RMR76 values ranging from 25 to 60. A Neural Network analysis of this data has been added and compared to the existing Span Design data of 292 case histories. Ground support is almost always used in weak rock environments, though the type of support used can vary widely. The development of the weak rock augmented Span Design Curve has also been calibrated to four different support categories; Category A: Pattern Friction Sets, Category B: Pattern Friction Sets with Spot Bolting of Rebar, Category C: Pattern Friction Sets with Pattern Rebar Bolts and Category D: Cablebolting, Shotcrete, Spiling, Timber Sets or Underhand Cut and Fill. Category A is considered “Unsupported” with an average Factor of Safety less than 1.2. Categories B, C and D are considered “Supported” with average Factors of Safety greater than 1.2. All categories are compared the original Critical Span Design Curve presented by Lang (1994). However, only Category A can be accurately compared to the original Critical Span Design Curve as it is “Unsupported” as well. Category A yields good results, however, Categories B, C and D do not, but still demonstrate that spans can remain stable at lower RMR76 values. Design of underground man-entry type excavations in North America relies heavily upon empirical analysis. This design requires a higher Factor of Safety than other non-man entry type excavations. A comparison of the calculated ½ span failure Factor of Safety between all the categories is also presented. The contribution this research provides to the mining industry is the "Unsupported" Weak Rock Updated Span Design Curve and awareness pertaining to the potentially detrimental effects of using resin grounted rebar in weak rock masses and the false sense of security that the use of resin grouted rebar may instill. It is also shown that spans in the “Unstable” zone of the new “Unsupported” Weak Rock Updated Span Design Curve can possibly be stabilized if detailed engineering design is applied to obtain “Supported” status.

Full text

Abstract:

An explanation is provided for the slab behaviour in composite beams at web holes where the concrete slab carries heavy vertical shear. This is based on the truss concept, and requires consideration of shear studs in the hole region as vertical tension members. According to this, a structural action between the concrete slab and shear connectors for carrying or transferring vertical shear to the steel beam was clearly identified.
On the basis of the slab behaviour identified, truss idealizations capable of determining the slab shear carrying capacity in a rational manner were developed. Then, the ultimate strength for composite beams at web holes was formulated including the truss idealizations. Another ultimate strength analysis accounting for the slab shear carrying capacity in a simple manner, which was also developed during this research project, is given. This provided the fundamental solution procedure for the plastic analysis used.
A series of nine tests was carried out with particular attention being directed to the verification of the proposed truss analogy. The major test parameters included the configurations of the studs in the hole region, the width of the concrete slab and stud detailing near the high moment end of the hole. The ultimate strength predictions were made by the two methods developed, and compared with previous and present test results.

Abstract:

This dissertation investigates the casual relationship between trade openness and economic growth in a sample of 87 countries (developing & developed) during the period 1970-2013. According to the previous literature, the openness-growth relationship seems to be relatively unclear and inconclusive, although the general tendency is that openness has a positive impact on economic growth. Our empirical results confirm this ambiguous relationship and provide evidence which vary across model specification. Regarding of the per capita income regression for all countries, trade openness has a positive but not a robust impact on income, as the coefficient of openness is positive but at the same time insignificant. As far as growth regression is concerned, it seems that there is a positive relationship between openness and growth for all countries. More specific, for developing countries trade openness has a negative effect on income per capita and a positive one on income growth. On the other hand, a negative relationship between openness and income per capita and income growth presented in our results for developed countries.
