[petsc-users] Identifying processes

[Bartłomiej W]

Hello,

I was wondering if anyone could help me to identify processes in parallel execution. I run my app with mpiexec -n 2 and would like to be able to pick a single core to perform a task and be the only one to print instead of having n cores repeat the same thing.

PETSC_COMM_WORLD and PETSC_COMM_SELF both cause all processes to print for me, like there is no difference.

Thank you
Bartholomew
