Trackable RESources (TRES) Billing Weights¶
The above policy is in practice implemented through the Slurm Trackable RESources (TRES) and remains an important factor for the Fairsharing score calculation.
As explained in the ULHPC Usage Charging Policy, we set TRES for CPU, GPU, and Memory usage according to weights defined as follows:
| Weight | Description |
|---|---|
| \alpha_{cpu} | Normalized relative performance of CPU processor core (ref.: skylake 73.6 GFlops/core) |
| \alpha_{mem} | Inverse of the average available memory size per core |
| \alpha_{GPU} | Weight per GPU accelerator |
Each partition has its own weights
