Hi Ed, I tried a couple Bcast unittest with the same MPICH and valgrind version. I could not reproduce the problem on our side. Can you provide an example code that has this problem?

When I run valgrind on one of my MPI programs, I get a large number of reported leaks for PMPI_Bcast(). Am I doing something wrong? I thought that this version of MPICH, when used with configure flag --enable-g=mem,dbg,meminit, would allow valgrind to work on MPI programs without false positives. Any suggestion would be helpful. _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
