[Condor-users] How to allocate sequential slots for an MPI job

Subject: [Condor-users] How to allocate sequential slots for an MPI job

Our cluster of 8-core nodes is configured for dedicated jobs using MPI in the parallel universe.  Slots are assigned more or less randomly, so that if one looks at the "machine" file generated by mp1script it might look like this:

node1
node2
node6
node6
node7
node4
node6
node5
node7
node5
node8
node6
node7
node8
node5
node6

There is now a requirement for the slots to be assigned in sequence, so that all 8 cores are used in one node, etc.  Is this possible?

Thanks,
