Thanks for the message! Actually, I only have two client nodes. One have 4 dual-core AMD CPUs (total 8 logic CPUs). The other host has 2 dual-core CPUs (total 4 logic CPUs).
I use "qsub ./script.sh" to submit jobs. All the jobs use the same script. If I submit 12 jobs, only 6 jobs runs (4 on the first node and 2 on the other node) at the same time. Here is what I get if I do "print server" from qmgr.
