I will admit I have never tried to bill on a mixed way like this for
gpu. I have you tried doing gres/gpu:nvidia-l40s=10.0 I think the extra
= is throwing things off.

Thanks a lot, but I am unable to set different weights for different
partitions.
I tried with:
PartitionName=DEFAULT
TRESBillingWeights="CPU=1.0,Mem=0.25G,gres/gpu=nvidia-h100=20.0,gres/gpu=nvidia-l40s=10.0"
but:
[2025-12-12T14:59:14.741] error: Invalid unit type 'n'. Possible
options are 'KMGTP'
[2025-12-12T14:59:14.741] fatal: failed to parse tres weights str
'CPU=1.0,Mem=0.25G,gres/gpu=nvidia-h100=20.0,gres/gpu=nvidia-l40s=10.0'
while:
PartitionName=DEFAULT TRESBillingWeights="CPU=1.0,Mem=0.25G,gres/gpu=20"
works (or at least it is accepted)
Thanks, Massimo

That is correct. You need to set the TRESBillingWeight to get billing
for gpus.
