Hello, Sorry if this questions its not appropiate for the petsc-list, but I really want to known what happen when I'm getting differente KSP time results. For example, allocating two process in the same node I get 6.24 sec, and when allocating two process in two nodes (1 process per node) I get 4.7sec. Is there a memory contention problem in my node?? The problem get worst when increase the number of process. I send attached a snapshot of the results. I really appreciate any clue.
Thanks in advance. -- Pedro Torres GESAR/UERJ Rua Fonseca Teles 121, S?o Crist?v?o Rio de Janeiro - Brasil -------------- next part -------------- An HTML attachment was scrubbed...
