BBH benchmark results
by Erik Schnetter 29 Apr '18

29 Apr '18

I ran benchmarks on Graham for Ian's BBH benchmark parameter files. Since this measures OpenMP performance, I used a single node with 32 cores, varying the number of OpenMP threads. The results are in the repo next to the benchmark parameter files in a CSV file. The result is: With a single OpenMP thread, as expected no difference. For many (16) OpenMP threads, the new code is twice as fast. For intermediate cases, the new code is up to 10x faster. This is clearly because the old code behaves badly. -erik -- Erik Schnetter <schnetter(a)gmail.com> http://www.perimeterinstitute.ca/personal/eschnetter/

We should meet again to check off our TODO items: https://docs.einsteintoolkit.org/et-docs/Working_Group_on_Performance_Optim… Should we meet on Friday next week (last week Friday of the month) at 12:00 pm (noon) CDT / 17:00 CEST? This is the same time (in the US) as the kick-off call but one hour different in the EU due to summer time having kicked in there as well. Yours, Roland -- My email is as private as my paper mail.
