Perhaps there are naming issues here, or there are too many terms defined here. JSDL is only concerned with specifying the resource requirements for the allocation request, not with how those resources end up being used (i.e. using threads or processes). So the TileSize indicates how many cpus need to be allocated as a unit within one OS image (i.e. a group of cpus), and the CPUCount would tell you how many cpus are needed in total. I don't believe you need any more. If the job chooses to use processes or threads is independent of the allocation. So given this example:
tasks per job=3 threads per task=4 processors per task=4
TileSize = 4 CPUCount = 12 This can translate to the PBS syntax "nodes=3:ppn=4" or the LSF syntax "-n 12 -R 'span[ptile=4]'", and I'm sure others as well. To the entity making the allocation, processes or threads doesn't matter. -- Chris
