This won't work, as the qsub command line parsing code always requires a PE name for -pe.
Ok. I was not sure if OGE had a default way of telling it the Parallel name
to use if none was given.
So it's the syntax which is difficult for us OGE beginners. I am trying
to have OGE choose a default pe name, but *NOT* the number of cores (slots).
Without modifying Grid Engine, you can use a JSV or a qsub wrapper.
Unless *every single job* in your cluster is a parallel job, adding
"-pe" in the default request file is likely not something you want.
yes, I don't think so. We have both parallel & serial, but most jobs are
parallel.
So really how many PEs you have in your cluster??
Too many. It's a research cluster and most use MPI, but others have their own communication configuration. From what I can tell so far with OGE (correct me if I am wrong) compared to Torque which
is where I am coming from, the Parallel Environment is just a tag to define some parallel configs such as how to allocate cores (slots), etc. With Torque you request both nodes & cores in your job
script, so you can slice and dice fairly easily.
If anyone has a links / references on tips for transitioning from Torque to
OGE, please post.
Best,
Joseph
