• Partition Charge Rate is a constant value associated with each Slurm partition,
• Core proportion is the number of CPU cores per node requested divided by the total number of CPU cores per node,
• Memory proportion is the amount of memory per node requested divided by the total amount of memory available per node,

For Setonix CPU nodes, the charge rate is 128 SU per node hour, as each CPU node has 128 cores.

For Setonix GPU nodes, the charge rate is 512 SU per node hour, based on the difference in energy consumption between the CPU and GPU node architectures. Since there are fewer GPU nodes than CPU nodes, these GPU nodes are to be used solely for GPU-enabled codes. Thus, resource requests on GPU nodes are slightly different to CPU nodes as all requests are in units of GCDs, with 1 GCD = 1 Slurm GPU. Requests cannot be made based on memory but must be based on the number of GPUs to be used. 

Maintenance

Due to the cutting-edge nature of Setonix, regular and frequent updates of the software stack is expected during the first year of Setonix's operation as further optimisations and improvements are made available.
