Does anyone have any experience using Valgrind in the context of MPI runs or know if this is possible? I didn't find anything in the Valgrind-users archives, and found only a comment in the survey results that Valgrind has trouble with MPI command line arguments.

I believe people have used it successfully. In response to the comment about difficulty with command-line arguments, one user told me of how he does things: This of course is a problem of the MPI-implementation, in case it's no problem for You... I solved this problem putting valgrind as debugger into the MPIch-startup file (in this case starting with line 24 in mpirun.ch_shmem or similar for p4-device) -- therefore, my MPI programs are valgrind'able, easily I don't understand that, but I hope it helps you.
