Available Partitions

Partitions in Slurm are sets of computing nodes with dedicated queues. Typically, it is not necessary to request a specific partition. Without any special requirements, jobs will be scheduled to the c23ms partition (see below). If you request GPU resources, your job will be scheduled to the c23g partition.

However, in some cases it may be necessary to specify the partition:

  1. Greater Memory Requirements on Claix-2023

    The nodes in the Claix-2023 cluster offer three memory configurations: small, medium and large. The c23ms partition includes all nodes, the c23mm partition includes nodes with medium and large memory configurations, and the c23ml partition includes only nodes with the large memory configuration.

    This setup allows you to select the partition that meets your memory requirements, while also ensuring that all nodes are utilized, even if the c23mm or c23ml queues are empty.

  2. Testing Applications

    The devel partition is designed for quick testing of computing jobs, offering short wait but limited run times. You can find more information here.

Partition Overview

The following table gives an overview of the currently available partitions.

Partition Nodes Cores per node Memory per core1 Billing Remarks
c23ms 625 96 2540 MiB2 Regular Claix-2023 (small memory), default partition
c23mm 166 96 5210 MiB Regular Claix-2023 (medium memory)
c23ml 2 96 10560 MiB Regular Claix-2023 (large memory)
c23g 50 96 5200 MiB Using one GPU for one hour is billed as 24 core-h Claix-2023 (each node has four H100 GPUs)

1 GPU is limited to 24 cores and 122 GB
devel 2 96 975 MiB Free Designated for testing purposes. Maximum runtime of 1 Hour. Only few simultaneous jobs. Please use without project

  1. This is the default value and the recommended maximum for #SBATCH --mem-per-cpu ↩

  2. 1 MiB = 2^20 Bytes = 1024 kiB = 1048576 Bytes = 1.048576 MB ↩
