Hi folks, Is MPI suitable for running jobs on large clusters?? Is it best suited only for SMP ? I used MPI on relatively small cluster. But now i have to recommend MPI for a relatively large 600 node cluster. Shall I ?? The nature of jobs is well, processing tera bytes of data. Th

Re: [OMPI users] Perl and MPI

y supports SGE, so all you have to do is "mpirun" like usual and we take care of the rest. You may have to check your version of Open MPI as this capability was added in the more recent releases. Ralph On 9/13/06 8:52 AM, "Renato Golin" wrote: > On 9/13/06, imran shaik

[OMPI users] Why does openMPI abort processes?

Hi, I some times get this error message. " 2 addtional processes aborted, possibly by openMPI" Some times 2 processes, sometimes even more. Is it due to over load or program error? Why does openMPI actually abort few processes? Can anyone explain? Imran _
