Dear Andr? I'm embarrassed, it was always my mistake. I have scripts that generate these pbs and the option was always bad allocated for openmpi. I was using -np instead of -npool.
I will try again, in order to check the performance Thank you so much Joaquin On Sat, Aug 28, 2010 at 8:42 AM, Andre Martinotto <almartinotto at gmail.com> wrote: > Dear Joaquin, > > In principle the process of compilation appears to be correct. > > What is your execution command?
