Partitions & SLURM

To view information of the available nodes and partitions use the following commands

sinfo

For more detailed information for a specific partition

scontrol show partition <partition-name>

The login and control nodes of Elja host two compute clusters: HPC-Elja and HTC-Mimir. Partitions and groups are used to separate the two.

HPC-Elja : Available Partitions / Compute Nodes

5gpu-2xA10064 (2x32)192 (188)Dual Nvidia A100 Tesla GPU

Core to true (memory) ratio equates to 3.9Gb per core.

HPC-Elja : Job Limits

Each partition has a max seven (7) day timelimit. Additionally, the queues any_cpu and long are provided:

  • any_cpu, all cpu nodes, one (1) day timelimit
  • long, ten 48cpu and ten 64cpu nodes, fourteen (14) day timelimit

HTC-Mimir : Available Partitions / Compute Nodes

CountNameCores/NodeMemory/Node (Gib)Features
9mimir64 (2x32)256 (252)
1mimir-himem64 (2x32)2048 (2044)

Core to true (memory) ratio equates to 3.9Gb per core on the mimir partition, and 31Gb on the mimir-himem partition.

HTC-Mimir : Job Limits

Either partition has a fourteen (14) day timelimit.

SLURM Configuration

SLURM is configured such that 3.94GB of memory is allocated per core.

Available Memory

On each node 2-4 Gib RAM are reserved for the operating system images (hence the true value is in the paranthesis).
