Jana, I just performed the exact same test on my system - running the same versions of Maui and Torque. It responded the same way as yours. The first two nodes were listed as job exclusive, while the third node was not. The third node that was chosen by maui actually already had some of the processors in use. It should be noted that I really did get a total of 10 cpus available (3+3+4).
A further item to add to this discussion, is that the number of dedicated cpus on the system, actually exceeds the number of cpus available for the ppn=4 system in this case. Here are the three lines from "checknode" Dedicated Resources: PROCS: 16 Dedicated Resources: PROCS: 16 Dedicated Resources: PROCS: 24 Each of those nodes has 16 procs. This looks like a bug. Craig.
