[OMPI users] starting open-mpi

Hi all. I'm a new open-mpi user. I've downloaded the OpenMPI_v1.5.5-1_win32.exe file to install open-mpi on my dual-core windows 7 machine. I installed the file but now i can't compile my mpi programs. I use command below (in command prompt window) to compile my 'test.cpp' program: >> mpic++ -o te

Re: [OMPI users] MPI-IO puzzlement

what is the communicator that you used to open the file? I am wondering whether it differs from the communicator used in MPI_Barrier, and some processes do not enter the Barrier at all... Thanks Edgar world, I only use one comm on this code. world = MPI_COMM_WORLD CALL MPI_file_open(wo

[OMPI users] MPI-IO puzzlement

Hi all I'm trying to run my code in a cluster here with infiniband. It is in Fortran 95/2003 and uses MPI-IO for output. I'm using openmpi 1.5.5. It runs has been running fine but for a particular configuration, using all of the cluster cores (128, divided in 4 boxes with 4 Octo-core Optero

Re: [OMPI users] call to fork() error

I'm afraid I don't know the inner workings of R at all. They must have changed something between 2.13 and 2.15 such that they're now calling fork() after MPI_Init()... The problem is that OpenFabrics-based networks do things that make fork()... unstable (for lack of a longer description). Tha

[OMPI users] call to fork() error

I'm getting the following error when running an open-mpi job on a LSF cluster using a new version of R 2.15. I didn't get the error message when running previously using R 2.13. Could anyone point me to the possible cause, or how to find the offending code? I'm not a sysop, just a user. Th
