Profile test case

[ilectra]

DONE:

• [x] profile of tests/sp2n/Test_hmc_Sp_WilsonFundFermionGauge.cc done and stored in shared folder
  • [x] nsys GPU
  • [ ] ~ncu GPU~ will look when we move to GPU
  • [x] vtune CPU
  • [x] muProf CPU

Initial simple profiling done with nsys profile -t cuda --stats=true -o test01 ./Test_hmc_Sp_WilsonFundFermionGauge --grid 8.8.8.8 --mpi 1.1.1.1 --Thermalizations 0 --Trajectories 1

Result is in /home/dp208/dp208/dc-gree5/RAC16/ed_test/grid_test_202410/Grid/build/tests/sp2n/test01.nsys-rep

Waiting to also find a good way of profiling with ncu and also run a CPU profiled case before closing.

@asifsamiarain to produce vtune profile with CPU compilers for --grid=8.8.8.8 and for a bit larger system (maybe '16.16.16.16` or something)

Got an initial muProf case with AMDuProfCLI profile.

It created a report you can find in /home/dp208/dp208/shared/RAC16//home/dp208/dp208/shared/RAC16/AMDuProf-Test_hmc_Sp_WilsonFundFermionGauge-TBP_Oct-30-2024_16-10-52 -- however it provided quite limited information. I think I need to enable more flags to the profiler as the run took like 5s, but it's a start. I will try and read up on muProf in more detail to learn how to use it effectively.

Following still failing, seems due to wall clock limit (30m fail, 1h fail, 2h fail), as redone with 3h will update this note:
