Dear All, At QMUL we have a standing reservation to make sure that atlassgm,lhcbsgm,cmssgm are going to the same node. The problem is that altough there is a userlist some other jobs take the node when the farm is full. The atlassgm jobs then take a long time to get trough and the proxy expires. The corresponding sam tests then fail and the atlas vo is removed from the fcr. The question is: how do you make sure that a reservation is only used by a set of users or a set of group only ? I have copied the qmul maui configuration file below. ---- SYSCFG[base] PLIST=sl3,installs,athlon,sl4& #SYSCFG[base] PLIST=sl3:installs,athlon:sl4& GROUPCFG[lhcb] PLIST=sl3,installs& USERCFG[atlassgm] MAXJOB=1 PLIST=installs& USERCFG[cmssgm] MAXJOB=1 PLIST=installs& USERCFG[lhcbsgm] MAXJOB=1 PLIST=installs& SRCFG[installs] HOSTLIST=fe04 SRCFG[installs] PERIOD=INFINITY SRCFG[installs] USERLIST=atlassgm,cmssgm,lhcbsgm SRCFG[installs] TASKCOUNT=4 ------ Thanks for your help, Olivier. -- - O. van der Aa - Imperial College London - - LT2 Technical Coordinator - - tel: +442075947810, +442071005426 - - SIP: [log in to unmask] - - fax: +442078238830 - - http://surl.se/agtu -
