[Condor-users] Core detection - AMD 6180 SE

[Brian Candler <B.Candler@xxxxxxxxx>]

[Ubuntu 12.04, condor 7.8.1]

I am using some boxes with four AMD 6180 SE processors. Everything I can
find on the web describes these as "12 core" processors, which suggests I
have 48 real cores available.

I have configured condor with:

COUNT_HYPERTHREAD_CPUS = False
SLOT_TYPE_1 = cpus=100%, ram=95%, swap=100%, disk=100%
SLOT_TYPE_1_PARTITIONABLE = True
NUM_SLOTS_TYPE_1 = 1

and it tells me that there are only 24 cores ("DetectedCPUs" is 48, but
"TotalCPUs" is 24). That is, Condor says there is hyperthreading.

I think I'm not the first to come across this:
https://www-auth.cs.wisc.edu/lists/condor-users/2011-August/msg00005.shtml

/proc/cpuinfo shows core id 0..5 and 0..5 for the 12 cores on one physical
processor, and
_CONDOR_ALL_DEBUG=D_ALL condor_config_val -debug NUM_CPUS
shows these are considered by condor to be the same core.

If there hasn't been any progress on this, could it be added to "known bugs"
at http://research.cs.wisc.edu/condor/manual/v7.8/9_3Stable_Release.html
?

Thanks,

Brian.
