ACCRE personnel have developed two sets of utilization graphs as a way for users to see overall cluster usage.
The first set gives an overview of cluster utilization. It consists of three graphs showing the percentage of nodes and processors in use, the number of nodes and processors in use, and the number of active, eligible, and blocked jobs.
The second set gives more detailed information broken down by CPU architecture and Myrinet activity. On these pages, the left graphs show the number of PowerPC, Opteron, and P4 CPUs in use. The right graphs show the subset of PowerPCs and Opterons using Myrinet.
Both sets of graphs allow users to view activity over the last hour, 24 hours, week, month, and quarter. In this way users can determine both short term node availability and long term trends. The last hour and 24-hour graphs auto-refresh every 5 minutes with new data.
