I've tried my application with MPICH2 and OpenMPI only. The readline stuff works in OpenMPI as long as I don't start my application with mpirun. It does not work in MPICH2 irrespective of whether I start my application with mpirun or not.

My application starts on a workstation and spawns slave processes on cluster nodes. The application provides an interactive command shell and provides some GUI functionality using X.

It is likely that Open MPI won't work properly in this situation -- Open MPI provides basic I/O forwarding. I don't know if curses-based or readline-based applications will work through our forwarding.

Do you know if this application works with other MPI implementations?

Subject: [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.
