Using partitions

Using partitions

Kurzinformation

In general, you do not need to explicitly request a partition in your job script, since this is done automatically for you by depending on the project and resources you already requested in your job batch script.

Every project has a default partition and (eventually) additional partitions that jobs can be submitted to.


Detailinformation

In general it is not required to submit your job to a specific partition, since the selection is automated by the project and/or the specified job requirements. However, in some cases (e.g., performance analysis of specific hardware) it might be relevant.

Explanation of the billing values of the table:

Each job that runs on the HPC cluster consumes core-hours (cpu-hours); cpu, mem and gpu are billed as corehours.

cpu is the basic reference resource and has a value of 1 billing cost. Using all 48 cores in a c18m node is equal to a cpu billing value of 48. 
mem is billed as cores per gigabyte. Consider a c18m node with 48 cores and 192GB memory: 1 GB requested memory equals to 0.25 cores (billing), and 4 GB equal to 1 core (billing).
gpu: each c18g node has 2 gpus, thus 1 gpu equals to a half node, or 24 cores (billing)
