Proceeding under the assumption that condor does not directly support
fractional GPUs, I am trying what I read here:
https://www-auth.cs.wisc.edu/lists/htcondor-users/2020-December/msg00018.shtml:
You can get HTCondor to do this just by having the same device show up more than once in the device enumeration.
For instance, if you have two GPUs and your configuration is
MACHINE_RESOURCE_GPUS = CUDA0, CUDA1
You can run two jobs on each GPU by configuring
MACHINE_RESOURCE_GPUS = CUDA0, CUDA1, CUDA0, CUDA1
I have 1 GPU and this is what I have in my config file:
#use feature:GPUs
#GPU_DISCOVERY_EXTRA = -extra
MACHINE_RESOURCE_GPUs = CUDA0, CUDA0, CUDA0, CUDA0
and this env setting: CUDA_VISIBLE_DEVICES="0"
But when I run multiple jobs requesting a GPU they run serially, not
in parallel.
Has anyone been able to get something like this working?

and it is matching (I can see that with -better-analyze and in the
StartLog) but the job never runs, it stays in idle state.
