Abstract

The demand for high computing power has led to rapid deployment of large-scale parallel, cluster, and grid-based computing systems. A particular interest is that these computing systems enable parallelism to be exploited at all levels (thread, instruction, task, and program). However, investigating performance issues in such systems has proven to be a challenging task that requires the innovative performance analysis tools and techniques to keep up with the rapid evolution and ever increasing complexity of such systems. This talk highlights challenges, discusses techniques, and reports state-of-the-art and in-progress research of performance evaluation and measurement tools for assessing these computing systems.
