           Summary: PBS job submission when maxnodes greater than queue
                    limit
           Product: Swift
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Specific site issues
        AssignedTo: dk0966 at cs.ship.edu
        ReportedBy: wilde at mcs.anl.gov


Swift scripts will fail in the PADS "fast" queue as soon as the swift script
generates more jobs than "workersPerNode" because the fast queue is limited to
one node.

Trapping the pbs submit script (I think debug=true in the 

login1$ qsub PBS5612813565711306842.submit

which has:
#PBS -l nodes=2
#PBS -q fast

Gives:

qsub: Job exceeds queue resource limits MSG=cannot satisfy queue max nodect
requirement

We (swift developers) need to find out why the error message wasn't made
prominent.

We need to both document this limitation, make sure the error message gets to
the user, and document procedures for finding and debugging Swift's generated
.submit files.
