Dear Open-MPI users, I am new to MPI in general and also specifically to open-MPI. I am using an MPI ready tool (meep) for computations. Now I have installed meep-mpi compiled with latest version of open-mpi which I downloaded and installed locally (there is also a system wide open-mpi version available in my system) on a quad-processor PC. Now I have a, probably trivial, problem when trying to run meep-mpi with /local/bin/mpirun -np 4 /local/bin/meep-mpi
And that is that this command seems to spawn four copies of meep that does not collaborate, they run the same thing all of them some how. I have searched both the opmi and meep mail archives without finding anything about this and would very much appreciate any input available!
