[Mauiusers] Patch for nodeaccespolicy SINGLEJOB and MAXPS for SMPmachines

[Bas van der Vlies]

I have just installed maui 3.2.6p16 and i have still have the same
problem. I could apply the patch without any problems ;-)

My question is will the patch be applied, changed or rejected? See 
explanation below

Regards and Thanks

At our side we run one job per nodes and have an MAXPS setting of 600
hours and max walltime 120 hours. Our nodes have 2 processors. When the
user submits
an job for eg:
     1) qsub -I -lnodes=60:ppn=1 -lwalltime=10:00:00 ( will run )
     2) qsub -I -lnodes=60:ppn=2 -lwalltime=10:00:00 ( wil not run MAXPS
                                                       violation)

Now when job 1 runs is allocates the whole node and maui sees that it
oocupies 4 task ( 2 nodes and each node two cpu's = 4 tasks). So the
used tme will becalculated as 60 * 2 * 10 = 1200 hours. What is far more
then allowed!

The next example will only run one job instead of 2:
     qsub -I -lnodes=30:ppn=1 -lwalltime=10:00:00 ( will run )
     qsub -I -lnodes=30:ppn=1 -lwalltime=10:00:00 ( will not  run MAXPS
                                                    violation )

I have an patch that checks if NODEACCESSPOLICY SINGLEJOB is set. If so
then it forgets the cpu's per node.
