We're using PBS as queueing system, which works fine as long as we consider the cluster as 30 virtual processors (and use mpi to run md on 2,4,6,8 processors). Has anyone worked out how to configure pbs so you can submit jobs to a single processor without making the second processor in the node unusable? Best regards, Peter -- Dr. D.P.
