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.
