***************************************
HPC Compute Nodes Migrated to Ceph
***************************************

The Department of Statistics HPC now uses `CephFS <https://ceph.io/en/discover/>`_ for shared storage across the compute nodes (see :ref:`Storage <storage>` for detail). The following HPC compute nodes have been migrated to Ceph:


Slurm login nodes
====================

* slurm-hn04 (Can run VSCode Server)
* slurm-hn05


Cluster: srf_cpu_01
===========================

* barbary
* garganey
* grey01
* muscovy
* saxony (incomplete migration: non-functioning /scratch areas)
* swan01
* swan02
* swan03
* swan11
* swan12
* swan21
* swan22


Cluster: srf_gpu_01
===========================

* gaussgpu01
* greyostrich
* swangpu24

Cluster: swan
===========================

* rainmlgpu01


Access
==============
**Access through slurm-hn04 login node:**

Eg:

.. code-block:: bash

   $ ssh your-Stats-IT-Account@slurm-hn04
   $ srun -p swan02-debug --clusters=srf_cpu_01 --pty --nodes=1 --ntasks-per-node=1 -t 00:30:00 --wait=0 /bin/bash -l


.. warning::
   The following storage areas are being wiped and decommissioned. If you wish to keep any of your data, please ensure you move them to another location (see above). If you need any help with this, please :ref:`contact Stats IT <contact-stats-it>`.

    Files on /data/localhost/not-backed-up will now only be accessible through an srun, until the areas are decommissioned and wiped.

.. code-block:: bash

   * /data/localhost/$USER/
   * /data/localhost/not-backed-up/$USER/
   * /data/localhost/not-backed-up/scratch/$USER/
