[Swift-user] Can swift run multiple MPI jobs on a Cray XE6 node?

[Justin M Wozniak]

The best way to do this on the Cray is still to use aprun directly from 
Swift in the local provider (although I heard you were having problems 
with the current aprun installation on Beagle).  The new MPICH/Coasters 
features do not provide much to help with this but I am currently working 
on relevant improvements, and this is a use case that we would like to 
cover.
