How is the disk space organised on ARCHER?

There are currently two disk space areas on ARCHER.

  • HOME space
       /home/n02/n02/<userid>
    

This disk space is backed up by ARCHER so NCAS has limited space, an NCAS user allocation is therefore relatively small.

  • WORK space
       /work/n02/n02/<userid>
    

This disk space is NOT backed up and is the only disk space accessible by ARCHER batch jobs. NCAS has a large allocation and so an NCAS user allocation can be relatively large, up to a few Tbytes.

Important:
There is no specific scratch filesystem, and /tmp is not accessible by users from jobs running on the compute nodes. Thus users who desire a temporary scratch directory should set the environment variable $TMPDIR to point to a valid directory within their account on the work filesystem.
