[Condor-users] OSX SMP Woes



Hi,

We recently installed condor on an SuSE Linux SMP x86_64 box (the master) and two dual OSX G5s. Jobs will execute on the G5's but the scheduler rarely uses both CPUs. It also seems to be confused about what portion of the load is attributable to Condor. For example, in the condor_status output snippet below Condor reports that the VMs running condor processes are generating no load at all while the non- condor load is quite high. Running top on these machines shows that the condor process is responsible for the reported load and the machines are otherwise idle.

vm1@xxxxxxxxx OSX PPC Owner Idle 0.670 4000 0 +00:10:07 vm2@xxxxxxxxx OSX PPC Claimed Busy 0.000 4000 0 +00:00:04 vm1@xxxxxxxxx OSX PPC Owner Idle 0.980 4000 0 +00:20:07 vm2@xxxxxxxxx OSX PPC Claimed Busy 0.000 4000 0 +00:00:09

We're running Condor 6.6.10 on the AMD and PPC boxes. The Macs run OSX 10.4.4 with all patches applied. The Linux box runs SuSE 9.3 with the 2.6.11.4-21.8-smp kernel.

Any ideas about how to get the Macs to use both CPUs?

Thanks,
	Chance
