Summary
Analyzing the performance of HPC applications is difficult and often unintuitive. Techniques from the world of serial programming, such as profilers and wall-clock timers, do not fully reveal the properties of parallel programs. To provide an incisive view into performance, tools must be designed with parallelism in mind. This talk will present some advanced analysis techniques tailored specifically for parallelism. These capabilities, including multirun analysis and processor clustering, will be demonstrated using the Projections performance analysis tool.
