Hi! Thanks for the reply. So: should I be passing this along to Wolfram in hopes that they do something on the Mathematica side? It would be nice if I could pass a timeout as an option to the SGE function, but I'm guessing that's no simple task (a change in Mathematica).
Can I be doing something on the SGE side? I'd love it to just ALWAYS do DRMAA_TIMEOUT_WAIT_FOREVER. :) Any further clarification would be much appreciated.
