Wait times for jobs in the default queues may be affected by reservations on Polaris and the ALCF AI Testbed (Cerebras, SambaNova, and Graphcore systems) during the 2024 Argonne Training Program on Extreme-Scale Computing (ATPESC). Please note that nodes in these reservations may sit idle as ATPESC participants prepare jobs for submission. These queues are for use by registered participants during the event and will be monitored. Please contact support@alcf.anl.gov with any questions or concerns.
