Dear David,

Thanks a lot for your  answer! 
What would be a good starting value for the memory pressure threshold, to configure it right?

Hi,



The Torque 3 changelog says " when cpusets are configured and memory pressure enabled, add the ability to check memory pressure for a job. Using $memory_pressure_threshold and $memory_pressure_duration in the mom's config, the admin sets a threshold at  which a job becomes a problem".




Does it work for non-NUMA setup as well? I mean, if I configure it with --enable-cpusets only, but --disable-numa-support ?



Grigory,
As long as you set your cpuset up correctly (http://www.adaptivecomputing.com/resources/docs/torque/3-0-3/a.cmomconfig.php) it will work with or without numa support.
