For the pbs_server to communicate with each of the moms, it needs to know which machines to contact. Each node that is to be a part of the batch system must be specified on a line in the server nodes file. This file is located at TORQUE_HOME/server_priv/nodes. In most cases, it is sufficient to specify just the node name on a line as in the following example:
server_priv/nodes:
node001
node002
node003
node004
