I requested a change to the queueing systems for our machines in part based on the experience we had with temporary overloading of the queue. It is certainly possible to expand on this as more experienced is gained. The changes are summarized below. The main change is really that they are fairshare while it was setup as first-come first serve. The will prevent quees from being monopolized by a single user. For the purpose of production analysis the bramreco user will have a priority 3* that of others (this works well for start). The short high prio queue is intended for calibration runs, dst generations etc while the regular cas should be used for longer running jobs (acceptance maps, monte carlo). Flemming "The Brahms LSF queues have been reconfigured as requested by Flemming and their CRS nodes have been included in a new, separate queue. The queues are summarized as follows: brahms_cas prio=30 standard fairshare queue brahms_cas_short prio=50 like brahms_cas with 1hr cpu time limit brahms_crs prio=30 like brahms_cas, but on CRS nodes with different load scheduling requirement I (opfer Rind) will be turning the LSF daemons on for the CRS nodes, but the queue is currently closed. Flemming can activate the queue at his discretion." ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory tlf: 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov
