Subject: [OMPI users] prepend the standard output with rank of the process
From: Kamaraju Kusumanchi (kamaraju_at_[hidden])

When I use mpiexec from mpich2 1.05.p4, there is an option called -l.
Using this option with mpiexec prepends each line of the standard
output with the rank of the process. I am a big fan of this feature
and it helps in debugging. Is there any such simple trick to prepend
the standard output with the rank of the process? I am using openmpi
1.0.6 at the moment and can upgrade if 1.0.7 has this feature.

thanks
