Holger,
PBS as installed by OSCAR does not use one of its own schedulers, it uses maui instead. To configure maui to allow concurrent access by two jobs to a single node:
/op/maui/bin/changeparam NODEACCESSPOLICY SHARED
to reverse that decision:
/opt/maui/bin/changeparam NODEACCESSPOLICY DEDICATED
It becomes effective immediately, w/o restarting the scheduler. You might also want to change the maui.cfg file somewhere under /opt/maui to make the change permanent.
hope this helps,
Mike

Hello, I've insatlled OSCAR 2.0 on cluster of several machines with two Pentium 4 CPUs, but I am not able to run 2 jobs on each node thru PBS.I submit the jobs using "qsub -l nodes=1:ppn=1 job" This does use 2 CPUs on an other cluster with OpenPBS without Maui qstat -f gives the following information: exec_host = n14.ctlp/0 ... Rerunable = True Resource_List.cput = 01:00:00 Resource_List.ncpus = 1 Resource_List.nodect = 1 Resource_List.nodes = 1:ppn=1 what is exactly the same than under OpenPBS. I suppose that the probleme comes from Maui and/or the definition of the standard queue "workq" that does not allow to run two jobs on a machine with 2 CPU. file /var/spool/pbs/server_priv/nodes n14.ctlp np=2 all n15.ctlp np=2 all n16.ctlp np=2 all n17.ctlp np=2 all n18.ctlp np=2 all n19.ctlp np=2 all n12.ctlp np=2 all n13.ctlp np=2 all master.ctlp np=2 Thanks for your help Holger Schwenk ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Oscar-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/oscar-users
