Information on running parallel jobs on an Elan interconnect is now

in elan.runtime.requirements.txt.  I think most of this functionality belongs
in the partition manager and job manager.

The switch manager should monitor the health of interconnect resources,
so switch.manager.design.txt is pretty much empty, awaiting a generic
description of how we will do this for any interconnect.  The Elan specific
bits of this would go in elan.runtime.requirements.txt.

Hope that makes sense.
