[yt-users] Problem in running parallel yt on stampede

[Greg Meece]

Are you running on the login node?

I've seen this too when I try to use mpi4py in a script on the Stampede
login ode. Specifically, it fails in the 'from mpi4py import MPI' step.
This happens even if I am not using yt or not running in parallel.

mpi4py works fine (for me at least) in an interactive compute node. I
wonder if they have the login nodes set up  to discourage parallel jobs.
