This looks (very) familiar to an issue I brought up with the OpenMPI folks earlier this year. See ticket 1942: https://svn.open-mpi.org/trac/ompi/ticket/1942 As a 5 second summary, the ticket is closed, there is a FAQ for this, and at least the trunk versions of OpenMPI have a valgrind suppression file that you'll want to use. -tom ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
