Abstract:

Analyzing and understanding the performance behavior of parallel applicationson various compute infrastructures is a long-standing concern in the HighPerformance Computing community. When the targeted execution environments arenot available, simulation is a reasonable approach to obtain objectiveperformance indicators and explore various ''what-if?'' scenarios. In thiswork we present a framework for the off-line simulation of MPIapplications. The main originality of our work with regard to the literature is to rely on\tit execution traces.

This study evaluates the performance difference between hybrid and native mobile applica-tions when accessing the low level API. The purpose of this study is to find out the differ-ence in performance between the different methods for developing applications due to an increasing market for platform independent applications. Several benchmarks were created to measure the performance on the following criteria, execution time, memory allocation and storage space. The benchmarks were developed with a similar behaviour to match the functionality. The Titanium benchmarks were around 8.5 times larger

Parallel and distributed programming constitutes a highly promising approach to improving the performance of many applications. However, in comparison to sequential programming, many new problems arise in all phases of the development cycle of this kind of applications. <br/>For example, in the analysis phase of parallel/distributed programs, the programmer has to decompose the problem (data and/or code) to find the concurrency of the algorithm. In the design phase, the programmer has to be aware of the communication and synchronization conditions between tasks. In the implementation phase, th

As the current rate of improvement in processor performance far exceeds the rate of memory performance, memory latency is the dominant overhead in many performance critical applications. In many cases, automatic compiler-based approaches to improving memory performance are limited and programmers frequently resort to manual optimisation techniques. However, this process is tedious and time-consuming. Furthermore, a diverse range of a rapidly evolving hardware makes the optimisation process even more complex. It is often hard to predict the potential benefits from different optimisations and th

A major goal in software engineering is to reduce the cost of maintaining software systems. Finding design methods which make software more easily maintainable has thus been one of the most prioritized challenges during the past decade.

Abstract:

Understanding the performance of applications on modern multi- and manycore platforms is a difficult task and involves complex measurement, analysis, and modeling. The Roofline model is used to assess an application's performance on a given architecture. Not much work has been done with the Roofline model using real measurements. Because it can be a very useful tool for understanding application performance on a given architecture, in this thesis we demonstrate the use of architectural roofline data with measured data for analyzing the performance of different benchmarks. We first explain how

Abstract:

This research investigates approaches to improve the performance of multi-agent based simulation (MABS) applications executed in distributed computing environments. MABS is a type of micro-level simulation used to study dynamic systems consisting of interacting entities, and in some cases, the number of the simulated entities can be very large. Most of the existing publicly available MABS tools are single-threaded desktop applications that are not suited for distributed execution. For this reason, general-purpose multi-agent platforms with multi-threading support are sometimes used for deployi

Abstract:

Web applications are often described as being cross-platform. They are accessible from a multitude of different web browsers, which in turn are running on a multitude of different operating systems. For a time now, developers have used many different tools to create cross-platform applications for mobile devices with web technologies. However, these applications fail to deliver when taken out of their native environment, and often do not feel native at all. Enter Progressive Web Applications, PWA. PWA’s are applications written for the web with web technologies, running in a browser, but seas

Abstract:

Architecture simulation is an important performance modeling approach. Modeling hardware components with sufficient detail helps architects to identify both hardware and software bottlenecks. However, the major issue of architectural simulation is the huge slowdown compared to native execution. The slowdown gets higher for the emerging workloads that feature high throughput and massive parallelism, such as GPGPU kernels. In this dissertation, three simulation techniques were proposed to simulate emerging GPGPU kernels and data analytic workloads efficiently. First, TBPoint reduce the simulated

Abstract:

Future integrated systems will contain billions of transistors, composing tens to hundreds of IP cores. Modern computing platforms take advantage of this manufacturing technology advancement and are moving from Multi-Processor Systems-on-Chip (MPSoC) towards Many-Core architectures employing high numbers of processing cores. These hardware changes are also driven by application changes. The main characteristic of modern applications is the increased parallelism and the need for data storage and transfer. Resource management is a key technology for the successful use of such many-core platforms

Abstract:

The advent of multicore architectures has bred complexity for developers. Variability in scheduling and resource management makes predicting runtime behavior substantially more complex. In order to coop with the added complexity, developers need tools that grant transparency in the system. Usually, a number of key characteristics heavily determine the performance of an application. By building a framework that exposes these key characteristics to the developer, we empower him/her to more closely monitor the system and gain important insight into its behavior. Erlang is a concurrent functional
