TORQUE also requires that all node names be resolved to an IP address, so use the IPMIs of the nodes as dummy execution nodes, as shown in Listing 27.
Neither the scheduling node nor the execution node discard the job information until it is passed on to, and accepted by, the other node.
Both the scheduling node and the execution nodes maintain persistent information about the state of their jobs.
This ensures that the state can be recovered from either the scheduling node or the execution node in event of failure.
