Hello all I have an 8 node MPICH2 cluster that the basic tests ( mpiexec -n 8 hostname, mpiexec -n 8 cpi and mpiexec -n 8 hellow) all work normally I've installed pyMPI and it runs when called as $pyMPI on all 8 machines. However when I run $mpiexec -n 8 pyMPI or mpirun -np 8 pyMPI no prompt, '$' or '>>>', is returned. When I query each node '$ssh <node> ps -e | grep py' they all return pyMPI as an active process. I've let the command sit for the better part of an hour with no response. The same thing happens irrespective of values given to -n. The use of machinefile likewise has no impact. Any ideas?

You should be able to use pympi interactively, but it needs to be built properly. You should test the non-interactive method listed by Jairo. If that works, the most likely problem is that the build is missing some flags relating to enabling newline etc. There are some previous posts in pympi-users relating to this, but sourceforge isn't letting me look at them right now..

Assuming this compiles correctly, the required flags for interactive are per this example: $ CC=mpicc; ./configure -prefix=<inst path> --with-includes=-I<mpi path>/include --with-isatty --with-prompt-nl Jairo Serrano <jai...@gm...> wrote: Ben, use pyMPI with mpirun or mpiexec like this: $mpiexec -n 8 pyMPI <a_python_program.py> cordially, Jairo Serrano 2007/5/30, Ben Hitt < bh...@wj...>:Hello all I have an 8 node MPICH2 cluster that the basic tests ( mpiexec -n 8 hostname, mpiexec -n 8 cpi and mpiexec -n 8 hellow) all work normally I've installed pyMPI and it runs when called as $pyMPI on all 8 machines.
