Asher, this prof's jobs will likely be run by HIS grad students. Very few jobs are actually run by profs. 90+% are grad students. Also, I'm not sure how "nice" factors into it (if it's the Unix type of "nice" which assigns system resources). The cluster assigns the next job in line for which there are adequate resources. So if there's 300 processors free, one guy submits job A for 400 processors and then the next guy submits job B for 200 processors job B gets run immediately while job A goes on the queue. It's not usually an issue. Even the big jobs get run within a day or two.
