Q. Where should I run small jobs that only use CPUs?

A. The Casper cluster’s high-throughput computing (HTC) nodes. Why? Take a look at the specs. You’ll see that 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. Additional examples will be available soon.
