Trying to use valgrind on a program and getting a ton of MPI related
noise, totally swamping the memory problems in the program itself.
Looked at the FAQ and used the suppression file referred to there:
mpirun -np 2 -host newsaf.cluster \
To count up all of these messages, piped with:
2>&1 | grep PMPI_Init | wc
which returned 92 for the command above. Leaving off the
reduces the count to 4 (as well as the usefulness of valgrind for
finding memory leaks!) Those counts are unchanged when
is omitted, suggesting that it is ineffective on this combination of
OMPI and Valgrind.
Is there a suppression file for these versions that will shut down all
messages under PMPI_INit but still allow the messages from the program
