Ha - I'm not the only one doing libMesh stuff on a Friday night, huh? Any thoughts on our default and overridden threading grainsizes? I'm playing with them on MIC, and even for a 2D problem with Q2/Q1 Navier-Stokes, I can go from 1000 all the way down to 100 with no performance penalty. Even going down to 10 elements in the smallest range only adds about 10% overhead worst case.
I'm wondering if I ought to just check n_local_elem() each time we build a range and pick a grain size of n_local_elem()/n_threads()/N for some small integer N. --- Roy ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Libmesh-devel mailing list Libmesh-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-devel
