Cluster Usage Data
Starting in 1992, usage data was collected Athena-wide. The larvnet server snapshots cview data on an hourly basis throughout the day, and then averages those snapshots to create the average number of machines free per day. The minimum and maximum total number of machines are also recorded. (The total number of machines can decrease if a machine breaks or is taken out of service).
Starting in December 1998, usage data was broken down by cluster.
