That's not quite true. Provided there is a way of expressing it (JSDL
does not give us enough) coallocation can be supported by the EPS,
though it would just be returning possible coallocation plans and not
ones backed up by hard reservations. (As you said in text I elided, that
is stuff that is up to the job manager and reservation service). Just as
with the CSG, arranging for the EPS to return an ordered set of plans is
likely to be the right approach, especially as it allows the JM to
decide what to do if the first plan falls through (and different plans
might be needed depending on exactly what happened too).
