CE install notes
CE templates
for all nodes that have more than 2 slots per node calculated as WN_CPUS[n]*WN_CPU_SLOT (with default to 1 and 2 resp)
variable WN_CPUS = nlist( "node13-16.wn.begrid.be",2, "node13-17.wn.begrid.be",2, "node13-18.wn.begrid.be",2, );
so if you want to support 8 job slots on the dual quadcores, set variable WN_CPUS = nlist( 'machinename',4)
For partitions/logical volumes please use the following format:
disk = [ 'phy:/dev/lvm/CE,xvda,w' ]
Select WN by CPU speed
'GlueHostProcessorClockSpeed' defines CE_CPU_SPEED
== How to enforce using certain WN's? ==
- variables foreseen in the templates to make the SRs.
in glite/glite31/common/maui/server/config
- In the maui config:
> SRCFG[jens] > HOSTLIST=worker8.atlantis.ugent.be,worker13.atlantis.ugent.be,worker15.atlantis.ugent.be,worker21.atlantis.ugent.be,worker25.atlantis.ugent.be,worker26.atlantis.ugent.be,worker27.atlantis.ugent.be,worker28.atlantis.ugent.be,worker29.atlantis.ugent.be > SRCFG[jens] TASKCOUNT=9 RESOURCES=PROCS:-1 > SRCFG[jens] PERIOD=INFINITY > SRCFG[jens] STARTTIME=00:00:00 ENDTIME=24:00:00 > SRCFG[jens] GROUPLIST=betest > SRCFG[jens] ACCESS=DEDICATED > SRCFG[jens] PRIORITY=1000
- in site/torquemaui there's a variable CE_QEUES. These are grid queues (i.e published queues).
If you want to add queues to eg VO betest do the following: (eg put this after the first generic betest queue (warning: the queue names should contain no "-"):
>queues['vos']['betest']=nlist("betest","betestfirsthalf","betestotherhalf"); >queues['attlist']['betestfirsthalf'] = queues['attlist']['betest']; >queues['attlist']['betestotherhalf'] = queues['attlist']['betest'];
How can one enforce to use only the WN's in one list and not in the others in a jdl file?
>Assign them to different queues. >(e.g. you have 3 betest queues, one for each SR and one for all).
