Analyst uses the Torque command "pbsnodes" to determine the number of nodes, number of cores, and number of cores per node on your cluster. Some commercial clusters do not expose the functionality of "pbsnodes" to users. In that case, your .bashrc file should define the three environment variables NUM_NODES, NUM_TOTAL_CORES, and NUM_CORES_PER_NODE, with actual values as given by your cluster administrator.
To ensure that all processes running on your cluster post their messages to the Analyst job log in real time, you should edit the /var/spool/torque/mom_priv/config file to set the $spool_as_final_name flag to true as shown in the following figure:
Without this flag setting, the messages will not be displayed until the end of the simulation.
