KAROLINA GPU CAPACITY REDUCED

2026-08-30 21:13:51

Outdoor temperatures currently exceed our cooling capacity. To protect the hardware, most GPU nodes on Karolina are placed under a SLURM reservation daily from 11:00 to 16:00 CEST (no jobs will run during this window). GPU jobs requesting more than 19 hours of walltime might not start while the reservation is in effect — please size your walltime carefully. We apologize for the inconvenience.
