• Reinstatement of file purging of personal /scratch files on Afton and Rivanna

    On Sep 1, 2024 RC system engineers will reinstate a file purging policy for personal /scratch folders on the Afton and Rivanna high-performance computing (HPC) systems. From Sep 1 forward, scratch files that have not been accessed for over 90 days will be permanently deleted on a daily rolling basis. This is not a new policy; it is a reactivation of an established policy that follows general HPC best practices.
    The /scratch filesystem is intended as a temporary work directory. It is not backed up and old files must be removed periodically to maintain a stable HPC environment.
    Key Points: Purging of personal scratch files will start on Sep 1, 2024.

  • Scratch Recovery with Globus

    Globus is a simple, reliable, and fast way to access and move your research data between systems. Researchers can transfer data from their old scratch directories to new scratch via a single web interface - no software download or installation is necessary.
  • Rivanna Storage

    There are a variety of options for storing large-scale research data at UVa. Public and Internal Use data storage systems can be accessed from the Rivanna and Afton high performance computing systems.

Slurm jobs run against /home will be slower than those run against /scratch. The /home directory is a personal storage space that is not shareable with other users.

  • `/scratch` Policy Enforcement

    Beginning 10/14/2019 RC system engineers will begin actively clearing /scratch files that have not been accessed for 90 days. /scratch is intended as a temporary work directory (90 days maximum).
    It is not backed up and needs to be purged periodically in order to maintain a stable HPC environment. We encourage users to back up their important data.
    RC offers several low-cost storage options to researchers.
