The overall Cluster Load is computed from the 1-minute load averages (as reported by ruptime) for all processing nodes. Administrative server load averages (file, database, login, and batch servers) are not included in the Cluster Load calculation.

Allocated Resources indicate the percent of the computational nodes (again, excluding the servers) that are allocated as "busy" by the Batch Queue System.

The tan shaded region (if present) indicates nodes that are reserved for interactive programs and are excluded from the batch system. A separate load indicator shows the load for the interactive nodes.

The gray shaded regions (if present) indicate offline nodes. The cluster loads can not enter the grey regions; however, due to a quirk in the batch scheduler accounting, the allocated resources may sometimes extend into either the grey region or the tan (interactive) region.

The ambient room temperature is monitored as a precaution. Under normal conditions, the room temperature should stay below 70°F. The Cluster begins to take preventative action if the measured temperature rises above 74°F.
