Historical Scheduling and Usage Breakdowns

On this page we present historical information of the scheduling coefficient (which indicates queue time) and usage broken down by quarter.

Scheduling Coefficient by Quarter

The heatmaps below provide information on the mean queue times on ARCHER over pst periods for different job sizes/lengths. The colour in the heatmap indicates the mean queue time as measured by scheduling coefficient for each class and the number in the box is the number of jobs of that class.

The scheduling coefficient is the ratio of run time to run time plus queue time and, as such, represents the fraction of the time in the queue that was spent running. A value of 1 indicates that the job started instantaneously and a value of 0.5 indicates that the job queued for the same amount of time that it ran for.
