DSI Cluster Impact

The University of Chicago Data Science Institute operates a shared GPU cluster for research and teaching across the University. This site reports what that machine actually delivers — updated nightly, computed from Slurm accounting records, and published with its methodology attached.

How busy is the cluster?

GPU-hours per day

Allocated, idle, and unavailable GPU-hours, stacked to total installed capacity. Drag the slider to change the range; hover for exact figures.

Utilization and availability

Utilization is allocated GPU-hours divided by the GPU-hours the scheduler could actually offer. Availability is the share of installed capacity that was up and schedulable.

Who uses it?

GPU-hours by research group

Most recent full year. Groups below the anonymity threshold are combined into “Other”; their usage still counts toward every total on this page.

When the cluster is busy

Mean GPU-hours allocated by hour of day and day of week, over the last 90 days.
