Casper changes coming to improve throughput, simplify job scheduling

February 22, 2021 Updated: March 2, 2021

Two major changes to improve job throughput and simplify job scheduling will be made to the Casper cluster during the system maintenance downtime scheduled for March 9-10. As announced late last year, 64 nodes will be added to the system and configured similarly to Casper’s existing non-GPU nodes. This expansion will enable high-throughput computing (HTC) on Casper for batch jobs and tasks that...
