I’d like to create python programs that use mpi4py and thus I’d like to run them using the following command:

mpirun -np 4 python script.py

I tried to create a shell script which does this and use it as a python interpreter but eclipse rejects the shell script. I tried to redirect the output (so that it doesen’t show the mpi-stuff but soley prints the python-output of the first node).

If I run the script in the console using the interpreterinfo.py script to test the interpreter it gives exactly the same output as if I run it only through python.

It somehow seems that the script isn’t executed properly by eclipse or that the output is not going into stdout.

Can anyone help?

    I don’t think you should try to configure mpirun as the python interpreter… Instead, configure the python interpreter as usual and just create a python module that’ll do the launching for you and launch that module instead… (or create an external launch in run > external tools)

    It’d be strange that mpirun is the actual python interpreter, because that way when requesting a code completion for builtins, pydev would launch the mpirun and it’d create 4 processes for code-completion? The same would apply to other things such as debug, coverage, etc…
