Host Resolution
The TORQUE server host must be able to perform both forward and reverse name lookup on itself and on all compute nodes. Likewise, each compute node must be able to perform forward and reverse name lookup on itself, the TORQUE server host, and all other compute nodes. In many cases, name resolution is handled by configuring the node's /etc/hosts file although DNS and NIS services may also be used. Commands such as nslookup or dig can be used to verify proper host resolution.
Invalid host resolution may exhibit itself with compute nodes reporting as down within the output of pbsnodes-a and with failure of the momctl -d3 command.
