The error in that ticket is about uninitialised reads which do happen and are semi-expected with socket programming. The error in this email is about a crash (segfault) in the open mpi library, I doubt the two are related. > 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. I wasn't aware that OpenMPI now ships with a suppression file, if it does I'd suggest using it, it'll help separate out the errors from the noise. Ashley, -- Ashley Pittman, Bath, UK.
