The complexity of modern High-Performance-Computing systems impose great challenges on running parallel applications efficiently on them. Performance analysis is therefore a key issue to identify bottlenecks and efficiency problems in HPC applications in order to improve and optimize the performance of these applications. We start with an overview of different performance problems whichfrequently occur in parallel applications and give an introductions to the concepts of performance analysis. In the second part we will discuss selected performance analysis tools in more detail and show how to use them in order to identify bottlenecks. |
