cannot set TRESBillingWeights to partitions

[metelkin]

Good day!
I could not find any reference in the CycleCloud or azslurm documentation that explains how to set the TRESBillingWeights parameter for individual partitions. My goal is to charge a fractional CPU cost for an HTC queue. In a classic on-prem slurm.conf I would simply write:
PartitionName=htc Nodes=ccw-htc-[1-16] DefMemPerCPU=3840 TRESBillingWeights="CPU=0.0003" MaxTime=INFINITE State=UP
Is there a recommended way to pass TRESBillingWeights through CycleCloud templating?

Hello there,

We try to setup the most basic slurm config, without too many specific customizations. In your case, this can easily be added in slurm.conf through the UI and it will append it in addition to our slurm.conf

Thank you for your reply.
The option (Slurm Configuration in Advances Settings) really helpful for slurm configuration updates sometimes.

But unfortunately it seems it cannot set up or update partitions configuration.

1. The partitions are initialized in azure.conf and there is no mechanism to update partitions by extra lines
2. I attempted to use the default option PartitionName=DEFAULT TRESBillingWeights="CPU=0.0003", but it still didn’t work because the "Slurm Configuration" placed the directive at the end of the slurm.conf file after azure.conf part. So DEFAULT options are ignored.

As for me the best solution would be to have a special key in NodeArrays to add extra settings like you did for dynamic partition settings.
