We've tested to date the following: 1) OpenPBS w/Maui 2) SGE (free edition) 3) Platform's LSF 4) Maui/ME The problems of each: 1) Hangs; has tendency to put a job in a wierd state, that sends thousands of email messages saying so; only way to clear is stop the master, and delete the job file by hand. 2) Scheduler doesn't work very well - wants to run all the small jobs first, priorities only apply after jobs are sorted by size. 3) Can be expensive. BUT, we got it perform just as well as OpenPBS w/Maui. Very configurable; even has a plugin scheduler with Maui scheduler support. 4) If you can get to even install and run correctly, please send me email - we'd like to know what you did. We also looked for other schedulers with MPI support - this is all we could find. Again, if you know of a scheduler not on this, please email us (with a pointer to the section of documentation that states this), and we will add it to the test.
