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 raju
