what does running

 

   condor_gpu_discovery  -properties -extra

 

show on that node?  what about

 

   condor_gpu_discovery  -properties -extra -not-nested

 

 

I notice you are using the -not-nested argument,  the new submit keywords for GPU matchmaking like  gpus_minimum_memory = 0.1 require that the GPU properties be nested.  Although those new submit keywords have a known bug with the version of HTCondor you are using, and should not be used before 23.7

Our system does not seem to pick up GPU memory. e.g.

condor_status --gpus

Name                        ST User                GPUs GPU-Memory GPU-Name            

 

slot1@xxxxxxxxxxxxxxxxxxx   Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxx      Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxxxx    Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxxxx    Ui _                      4            NVIDIA A100-SXM4-40GB

slot1@xxxxxxxxxxxxxxxxxxxx  Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxxxx    Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxxxxx   Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxxxxx   Ui _                      1            Tesla T4            

slot1@xxxxxxxxxxxxxxxxx     Ui _                      1            Tesla T4         

 

and adding a gpus_minimum_memory = 0.1 results in no matches.

Weâre using use feature :GPUs and config_config_val -dump |grep GPU shows
