Hi everybody! I have two issues with our maui installation (maui-3.2.6p21 and torque-2.1.11, both compiled from scratch running on an Ubuntu system).
We have a setup where all available machines are in the queueing system but only dedicated computer-servers are running calculations all the time. Desktop machines (with users in front of them) are available for calculations only after-hours and on weekends (with the exception of jobs run by the user of the desktop). I implemented this setup through statements like: NODECFG[machine1] MAXLOAD=1.8 SRCFG[machine1] USERLIST=user1 SRCFG[machine1] OWNER=USER:user1 SRCFG[machine1] HOSTLIST=boron SRCFG[machine1] PERIOD=DAY DAYS=MON,TUE,WED,THU,FRI SRCFG[machine1] STARTTIME=9:00:00 ENDTIME=18:00:00 SRCFG[machine1] ACCESS=shared in maui.cfg. This works very well - in principle. However there are two situations where maui doesn't get it right. 1) The maui process is restarted. When I restart maui for some reason it completely ignores all reservations right after startup, only after some time has passed the configuration works as expected. This often causes desktop machines to start calculations even though they should be kept available for the user actually sitting in front of it. At the moment my work around id to disable the queue in torque and re-enabling it after maui has run for a couple of minutes - works fine but is not very convenient. 2) Weekends. Sometimes maui will start jobs on Friday evenings (Fri, 6pm - see configuration above) that actually run longer than Monday 9am. This, of course, causes users to find a job running on 'their' machine when they return after the weekend. I have not yet found a way to fix this. I suspect it might be a problem of maui's 'horizon' - It might not know on a Friday night what is supposed to happen on the next Monday morning. Any suggestions?
