Partitions

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:

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.

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.
