Thanks Barry,
I thought this worked at some point ... anyway I would like to get some
threaded examples of AMG.
I know that this applications solves will not run faster with threads, they
are latency bound, but I need to demonstrate this with data. I need to say
the solve is threaded on Titan. If I use CG + GAMG with threads:
-threadcomm_nthreads 8
-threadcomm_affinities 0 1 2 3 4 5 6 7 ?????
-threadcomm_type openmp
Then would I get threaded MatVec and other CG + MG stuff? I know this will
not be faster but I just need data to corroborate what we all know. And I
don't care about setup.
Mark
