Hi. I'm new to submitting jobs through Grid Engine, and have skimmed users guides, googled, etc., without figuring this out and could use some advice.
#1: I need to be able to submit jobs that will start up several distinct executables that need to run at the same time. If I was doing my work in an interactive shell, I'd just do something like this: $ foo & $ bar & $ baz & . . .and so they'd all start around the same time, run in the background, and complete around the same time. The executables talk to each other through the output files, and I don't need to do any more than that. But from what I've read in users guides, I shouldn't invoke processes in the background in jobs submitted to GE; and that makes sense to me, since then the interpreter would reach the bottom of the script while the executables are still running. But submitting a script with contents of: foo bar baz won't work, because those are run sequentially. The only thing I can think of to do is to separate each executable out into its own job submitted to the queue; but then I need to guarantee that they start executing at the same time, rather than two starting while one sits in a pending state. #2: Normally, when running these interactively, I'd set them up for Open MP use doing something like this: $ setenv OMP_NUM_THREADS 1 $ foo & $ setenv OMP_NUM_THREADS 2 $ bar & $ baz & etc. Will instructions like that be honored within a script submitted to the scheduler? Any advice on these would be very helpful. Thanks much. -c
