[OMPI users] Using dynamic process management without mpirun/mpiexec

Hi all, Does OpenMPI support dynamic process management without launching through mpirun or mpiexec? I need to use some MPI code in a shared-memory environment where I don't know the resources in advance. Damien

Yes, that's right. It will launch a singleton, and then add slaves as required. Thank you. Damien On 24/02/2010 6:17 PM, Ralph Castain wrote: Let me see if I understand your question. You want to launch an initial MPI code using mpirun or as a singleton. This code will then determine

slightly wrong for 32-bit Windows, there won't be a Win64 x64 prompt. There will be only one command prompt option on a 32-bit install (use that), and CMake will have set you up with a 32-bit build by default, so you'll be fine. Post back if you need help. Damien On 12/07/2010 5:47 PM, Alexand
