OMPI 1.4.3 Valgrind 3.5.0 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 \ valgrind \ --leak-check=full \ --suppressions=/opt/ompi143/share/openmpi/openmpi-valgrind.supp \ hmmfetch \ --mpisplit \ /usr/common/BLASTDB/PFAMDIR3/Pfam-A.hmm CagE_TrbE_VirB 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 --leak-check=full reduces the count to 4 (as well as the usefulness of valgrind for finding memory leaks!) Those counts are unchanged when --suppressions=/opt/ompi143/share/openmpi/openmpi-valgrind.supp 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 being tested???
