CISL recommends running small jobs that use only CPUs on the Casper cluster’s high-throughput computing (HTC) nodes. Casper has 64 HTC nodes specifically for running small batch jobs.

It also has:

  • More shared resources than the Cheyenne share queue
  • A far higher concurrent-use limit for CPU cores than Cheyenne: 468 vs. 36.
  • More available memory, plus NVMe swap for overflow.

Here’s an example script for running an HTC job on Casper.
