Allow user to specify parallel environment for SGE jobs #435

Open jpellman opened 9 years ago

jpellman commented 9 years ago

Currently, C-PAC generates SGE job files that presuppose the existence of a parallel environment named 'cpac' on the cluster. Users might use a parallel environment with a different name, and we should either allow them to specify this name or have a configuration script create the 'cpac' pe for them.

I would prefer the latter. CPAC requires that all of the processors that are made available to a job be on the same node, which requires a special settings in the parallel environment. Since this is not default behavior, and some systems may not be configured in this way, I would rather us use a "special" parallel environment that is configured specifically for CPACs use.

BTW danny should have something like this already that he uses for AWS.

I have the scripts to do this. It's relatively simple, and a good idea. The typical parallel environment we recommend for C-PAC users is set up, such that, any one SGE job is guaranteed to never be spread across multiple nodes (in our case, any subject is guaranteed to run all on a single node). That's not to say that the job is the only job running on that node - if the node has 8 cores and we allocate 4 cores per subject, the parallel environment will actually launch two jobs (subjects) to be run on that node.
