Usable Hardware
The HPC JupyterHub service allows users to use the same hardware (Slurm partitions, nodes, Filesystems, etc.) that they can already use in the existing RWTH High Performance Computing through the Slurm Workload Manager.
Usable partitions
All hardware within these partitions can be used in the HPC JupyterHub c18m and c18m .
Requesting resources
Just like normal Slurm batch jobs, the HPC JupyterHub users need to specify the amount of hardware they want to use.
It is recommended to select their requirements: memory (max 187GB per Node), cores (48 max per Node), GPU( max 2 per Node) and runtime!
Waiting for resources
Because the HPC JupyterHub uses Slurm to allocate HPC hardware, users that require GPUs or above 8 cores, need to wait for their request to be processed in the Slurm queue.
Queuing is inherent to HPC hardware and HPC workflow.
To quickly get access to a JupyterLab instance users must request 8 or less cores.
Limitations
Hardware that is not available through Slurm cannot be currently used by the HPC JupyterHub.
