Abstract:

Clusters of workstations are becoming increasingly popular as a low-budget alternative for supercomputing power. In these systems,message-passing is often used to allow the separate nodes to act as a single computing machine. Programmers of such systems face a daunting challenge in understanding the performance bottlenecks of their applications. This is largely due to the vast amount of performance data that is collected, and the time and expertise necessary to use traditional parallel performance tools to analyze that data. The goal of this project is to increase the level of performance tool

Abstract:

Includes bibliographical references (p. 113-115).<br>Under certain conditions Iterative Feedback Tuning (IFT) may produce a controller that cancels the poles of the process and as a result can give a closed loop that has poor internal performance. The disadvantage of this is that the closed loop will have poor input disturbance rejection. A solution for ensuring that IFT does not have poor internal performance is to make sure that the disturbance rejection is adequate. However an adequate input disturbance may lead to other undesirable dynamics in the closed loop performance. These are such as

Abstract:

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

Abstract:

Improving program performance through the use of multiple homogeneous processing elements, or cores, is common-place. However, these architectures increase the complexity required at the software level. Existing work is focused on optimising programs that run in isolation on these systems, but ignores the fact that, in reality, these systems run multiple parallel programs concurrently with programs competing for system resources. In order to improve performance in this shared environment, cooperative tuning of multiple, concurrently running parallel programs is required. Moreover, the set of p

Abstract:

Modern computer software systems are complicated. Developers can change the behavior of the software system through software configurations. The large number of configuration option and their interactions make the task of software tuning, testing, and debugging very challenging. Performance is one of the key aspects of non-functional qualities, where performance bugs can cause significant performance degradation and lead to poor user experience. However, performance bugs are difficult to expose, primarily because detecting them requires specific inputs, as well as specific configurations. Whil

Abstract:

Most applications spend a significant amount of time in the iterative parts of a computation. They typically iterate over the same set of operations with different values. These values either depend on inputs or values calculated in previous iterations. While loops capture some iterative behavior, in many cases such a behavior is spread over whole program sometimes through recursion. Understanding iterative behavior of the computation can be very useful to fine-tune it. In this thesis, we present a profiling based framework to understand and improve performance of iterative computation. We cap

<p>Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems.

Unfortunately, the system class can change when the running applications change. The model for self-tuning operating system is based on a monitor-classify-adjust loop. The idea of this loop is to continuously monitor certain performance metrics, and whenever these change, the system determines the new system class and dynamically adjus

Parallel program design and development is inherently more difficult than its sequential counterpart. People who have traditionally programmed on sequential machines are now called upon to deal with new and complex tissues when trying to control a number of entities executing concurrently. In the quest to produce application programs that take advantage of the power of the underlying hardware, usable and efficient tools are required to assist with the task of performance analysis and tuning. A large number of tools are described in the literature, but the results of tool use are disappointing.

Abstract:

The Collaborative Contrabass project is a multi-faceted exploration of double bass chamber music encompassing musicological research, performance and reflexive practice. The intention of this research is to provide a deeper understanding of the role that the double bass has played in chamber music since the eighteenth century and the challenges this repertoire presents for the performer. Its wider aim is to promote the double bass as a collaborative instrument and encourage the double bass community to embrace a wider range of chamber music repertoire. The research holds particular relevance t

Abstract:

High Performance Computing (HPC) has become an indispensable tool for the scientific community to perform simulations on models whose complexity would exceed the limits of a standard computer. An unfortunate trend concerning HPC systems is that their power consumption under high-demanding workloads increases. To counter this trend, hardware vendors have implemented power saving mechanisms in recent years, which has increased the variability in power demands of single nodes. These capabilities provide an opportunity to increase the energy efficiency of HPC applications. To utilize these hardwar
