New GPU syntax and software environment on Derecho and Casper

November 6, 2025

As previously announced, the GPU specification syntax for PBS jobs has changed as of the Nov 4-5 maintenance. The gpu_type resource is no longer specified on the job, but rather on chunks within a PBS select statement. For example, here is how you would now ask for 1 node of 4 A100s on Casper: #PBS -l select=1:ncpus=128:mpiprocs=4:ngpus=4:gpu_type=a100 Additionally, we have expanded the gpu_...
