Hi all, Use sdiag to see if the backfilling is too slow. If it is, tune the scheduler parameters. There is a bf_max_jobs or something like this that will limit the number of jobs evaluated and will decrease considerably the scheduling time Regards, Carles Fenoy Barcelona Supercomputing Center El 21/05/2013 23:15, "Bjørn-Helge Mevik" <[email protected]> escribió:
