           Summary: multi-node coasters?
           Product: Swift
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Specific site issues
        AssignedTo: benc at hawaga.org.uk
        ReportedBy: aespinosa at cs.uchicago.edu


In a 1 coaster per node configuration.  Sometimes site policies only allow you
to submit a maximum number of jobs in the queue (e.g. 50).  thus even though
the score can reach up to 102, the maximum number of active jobs in a site is
only 50.

this can be worked around by requesting 2 or more nodes in a single job
submission.  We can use pbsdsh or equivalent in the LRMs.  Using mpirun can
also be explored.
