Jed, does the PETSc team have any experience with the NBC algorithm deadlocking with OpenMPI-1.7?
I know they don't officially advertise MPI_Ibarrier(), but it is there... See https://github.com/benkirk/mpi_playground.git - I've implemented the nonblocking consensus & it seems to work reliably with mpich-3 and mpt-2, but openmpi-1.7 randomly fails. Just curious if this is a known issue, although some quick searches do not reveal anything. -Ben ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
