File storage for computation
PDC has two file systems available for storing files for calculations that are being performed on PDC's systems:
- AFS, which is based on the Andrew File System, and
- Lustre, a parallel file system that satisfies the requirements for leadership class high performance computing (HPC) simulations.
Which system you should use to store your files depends on
- the amount of data you need to store, and
- how you will be using or accessing the data.
Basically AFS storage is for home directories with small amounts of data and is always backed up. Lustre is for fast parallel access to large amounts of data for HPC simulations and is never backed up. For further information regarding file storage for computation at PDC, see the sections about storing data and about file systems in the Support area.
