Minutes
GOMP vs LLVM libomp investigation (Paul Osmialowski, ARM)
Paul provided an overview of the findings on usage of GOMP vs LLVM.
Martin: Reminder ask for deck
[Martin]GCC bankend for GOMP - What toolchain was used?
[Paul] 2 - GCC version 5.3 Fedora? And GCC 7 from gitmaster
[Martin] What did you focus on during testing
[Paul] C++ Lulesh and C. No results from Fortran e.g fortran benchmarks. The results suggest the language does not matter
Suspect we can achieve libomp results with GOMP but suspect it will require substantial change in GOMP. Risk if we move towards
[Larry] genomics: Underlying analysis fits to that market. Agrees that we should work on this. It’s fits into the detail we had discussed
Takeharu: unable to comment,
Steve: Agree it’s one to work on but hard to prioritise based on what else needs to be considered
@Kanta to follow up with the toolchain team to scope and identify resourcing needs and risks
HPC Prioritisation heads up
All in agreement to get the ball rolling
Target to have all the prioritisation in before BUD17 face to face meeting so that we end the meeting with clear agreement on the engineering path.
@Kanta to email out.
