Decommissioning of the HPC cluster
Since January 15th 2025, the historical CNAF HPC cluster has been decommissioned. This section of the guide is kept for some time for reference and will be heavily modified as the HPC bubbles will be installed and made available to users of projects that requested their usage through a formal request to ICSC via the PICA portal.
If your use case has needs related to parallel computing, i.e. multinode-MPI or needs special computing resources such as Intel Manycore or NVIDIA GPUs, probably you need to access the CNAF HPC cluster, which is a small cluster (about 100TFLOPS) but with special HW available [9].
This cluster is accessible via the LSF batch system for which you can find instructions here [10] and Slurm Workload Manager which will be introduced hereafter.
In the following pages, few details on the account request and first access are given.
