Have you ported your applications to supercomputers and found they are not as fast as you expected? Do you want to know which sections of the application are limiting performance?
Performance analysis tools help software developers understand if their software performs optimally in HPC systems and if not, what are the causes for the restricted performance. This allows software developers to make informed and methodological decisions on what aspects of the code to improve in order to maximise the application performance.
Aimed at Independent Users, this training course will introduce the basic concepts in performance analysis and will demonstrate three different performance analysis tools available in the Hartree Centre Scafell Pike system: the Linux perf tool, the Intel VTune Profiler, and Nvidia Nsight Systems.
This course also includes a ‘bring your own code’ practical session where we encourage attendees to analyse their software with the tools learnt and, with the help of the lecturers, identify areas of the application that could be improved.Learning objectives
