Yah, about that patch... it didn't work so well. I found out later that in some cases Maui allocated 1 CPU to jobs. I think it happened when resources weren't available when the job was first submitted; subsequent attempts to run the job only got 1 CPU. > PS: why did nobody reply you? *shrug* because I hardly ever get replies when I ask people to test stuff. -- Garrick Staples, Linux/HPCC Administrator University of Southern California
