You'll want something like this:

require_gpus = GlobalMemoryMb >= 2048

To request a GPU with at least 2GB of GPU memory. The gpus_minimum_discovery is only in the 23.x feature branch I believe, not the 23.0 LTS or 10.9.

This seems to work on the 23 nodes:

Universe = vanilla
gpus_minimum_memory = 1MB
request_gpus = 1
Executable   = /usr/bin/echo
Arguments = hello compute
output           = h100.txt
error            = h100.err
Log          = h100.log


however, thereâs a warning

WARNING: the line 'gpus_minimum_memory = 1MB' was unused by condor_submit. Is it a typo?

Is that just a condor_submit bug?
