[OMPI users] MPI_Comm_spawn

What configuration do I need to run child/slave MPI processes created via MPI_Comm_spawn on another machine. Thanks. Saadat.

[OMPI users] MPI_Comm_spawn error messages

Good Day: I am getting the following error messages every time I run a very simple program that spawns child processes: [turkana:27949] [0,0,0] ORTE_ERROR_LOG: Not found in file base/soh_base_get_proc_soh.c at line 80 [turkana:27949] [0,0,0] ORTE_ERROR_LOG: Not found in file

unning this application? We have a known problem with comm_spawn from a singleton (i.e., if you just did a.outinstead of mpirun —np 1 a.out) - the errors look somewhat like what you are showing here, hence our curiousity. Thanks Ralph On 7/6/06 3:12 PM, "s anwar" <san...@gmail.com> wrot

[OMPI users] readline and mpirun

When I run my MPI enabled application via mpirun, my application command-prompt looses its readline editing capability. I was wondering if there is workaround. Thanks. Saadat.

[OMPI users] Why should the attached code wait on MPI_Bcast

Please see attached source file. According to my understanding of MPI_Comm_spawn(), the intercommunicator returned is the same as it is returned by MPI_Comm_get_parent() in the spawned processes. I am assuming that there is one intercommunicator which contains all the (spawned) child processes
