I am using a tool called starcluster http://star.mit.edu/cluster to boot up an SGE configured cluster in the amazon cloud. The problem is that it doesn't seem to be configured with any pre-set consumable resources, excepts for SLOTS, which I don't seem to be able to request directly with a qsub -l slots=X
. Each time I boot up a cluster, I may ask for a different type of EC2 node, so the fact that this slot resource is preconfigured is really nice. I can request a certain number of slots using a pre-configured parallel environment, but the problem is that it was set up for MPI, so requesting slots using that parallel environment sometimes grants the job slots spread out across several compute nodes.
Is there a way to either 1) make a parallel environment that takes advantage of the existing pre-configured HOST=X slots settings that starcluster sets up where you are requesting slots on a single node, or 2) uses some kind of resource that SGE is automatically aware of? Running qhost
makes me think that even though the NCPU
and MEMTOT
are not defined anywhere I can see, that SGE is somehow aware of those resources, are there settings where I can make those resources requestable without explicitely defining how much of each are available?
Thanks for your time!
