Preparation: Lectures about HPE and AMD profiling tools¶
As proper optimisation of code starts with understanding where the bottlenecks are, some understanding of profiling and profiling tools is very useful. Therefore we highly recommend hackathon participants to follow some lectures of the "Performance Analysis and Optimization Workshop that we have the week before.
It will be possible to follow the recommended lectures by Zoom so there is no need to actually join the workshop on-site.
Recommended lectures:
-
Monday May 11, 11:20: Introduction to Performance Analysis with Perftools
-
Monday May 11, 13:00: Advanced Performance Analysis
The lecture is followed by a half hour exercise session.
-
Tuesday May 12, 13:00: AMD Profiling Tools and GPU optimisations 1
The lecture is followed by a half hour exercise session.
-
Tuesday May 12, 14:50: AMD Profiling Tools and GPU optimisations 2
The lecture is followed by a half hour exercise session.

Projects¶
In alphabetical order:
-
Murphy is a multiresolution multiphysics code developed at MIT and Louvain-la-Neuve. It wasn't really selected as a hackathon project, but as one of the developers had questions in a LUMI ticket they were invited to come and discuss those and one person attended the hackathon for two days.
-
UppASD GPU port optimizations (Fortran code with OpenMP)
