Hello, I'm solving MPIBAIJI matrices using KSPCR preconditioned by a PCBJACOBI between sub domains and PCILU with a fill ratio of 1 on each sub domain.
Solving exactly the same linear systems, I notice that the solution is slower using v2.3.3p8 than with v2.3.0. The behavior is not very clear: v2.3.3p8 is generally slower (10 % or more) but on some systems it happen to be really faster (may be 40 %). Unhappily in my case at the end I'm always slower ... Did somebody noticed such behavior? Is there changes if I upgrade to current 2.3.3p13 version (I've seen a fix:" fix error with using mpirowbs & icc & ksp_view") ? Thanks, Etienne Perchat
