Hi,<br>
<br>
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&nbsp; which a job becomes a problem".<br>


<br>
Does it work for non-NUMA setup as well? I mean, if I configure it with --enable-cpusets only, but --disable-numa-support ?<br>
<br></blockquote><div><br></div><div>Grigory,</div><div><br></div><div>As long as you set your cpuset up correctly (<a rel="nofollow" target="_blank" href="http://www.adaptivecomputing.com/resources/docs/torque/3-0-3/a.cmomconfig.php">http://www.adaptivecomputing.com/resources/docs/torque/3-0-3/a.cmomconfig.php</a>) it will work with or without numa support.</div>
