[Opengeoscience-developers] Websockets and MPI

[Ben Burnett]

The Pi example came from http://mpi4py.scipy.org/docs/usrman/tutorial.html,
I just modified it to run in a websocket handler on cherrypy.

It looks like it's failing to spawn the processes using MPI. Do you get any
exceptions in the log?

You could try first running the Pi example from the above website in python
to make sure MPI is working on your machine.
