# Torque Resource Manager (`torque`)
<a name="schedulers.torque"></a>

**Note**  
Starting with version 2.11.5, Amazon ParallelCluster doesn't support the use of SGE or Torque schedulers. You can continue using them in versions up to and including 2.11.4, but they aren't eligible for future updates or troubleshooting support from the Amazon service and Amazon Support teams.

Amazon ParallelCluster versions 2.11.4 and earlier use Torque Resource Manager 6.1.2.
