[mpich-discuss] linux shell calls and mpi

[Pavan Balaji]

You should be able to reproduce the problem you are getting without MPI 
by doing:

% ssh <some_remote_host> python home/user/.../script.py

This is because ssh does not create a terminal for remote launches. You 
can force ssh to create a pseudo-terminal by passing -t. If you want to 
pass this option to mpiexec, you can set the environment variable 
HYDRA_LAUNCHER_EXTRA_ARGS=-t before calling mpiexec.
