Re: [OMPI users] Inter vs Intracommunicator...Who is the best?

. It is currently better in Open MPI to do a merge and use intracommunications. Thanks, Graham. --- Dr Graham E. Fagg | Distributed, Parallel and Meta-Computing Innovative Computing Lab. PVM3.4, HARNESS, FT-MPI & Open MPI Comp

Re: [OMPI users] MPI_Bcast/MPI_Finalize hang with Open MPI 1.1

it hangs.. let you know as soon as I find anything but right now I am testing using TCP. Can you let me know the exact path and LD_LIBRARY_PATH your using on odin? Thanks, Graham. -- Dr Graham E. Fagg

Re: [OMPI users] MPI_Bcast/MPI_Finalize hang with Open MPI 1.1

different answers on any of the nodes (other than their rank) then we (I) have a problem! Thanks, Graham. -- Dr Graham E. Fagg | Distributed, Parallel and Meta-Computing Innovative Computing Lab. PVM3.4, HARNESS, FT-MPI
