Scratch Space

Although each user's AFS home directory is available, AFS is not optimal for large volumes of file write activity. If your simulation requires / results in the generation of large data / log files, please consider using the node local temporary scratch space.

Node Local Scratch Space

As is typical for Unix systems, the /tmp area is available for node local temporary files. These files are only available on the particular node. Generally the cluster nodes have 40G or more of /tmp space available.


Any cluster user can store files in the /tmp area. Please create a subdirectory for your files to keep the top-level directory uncluttered.


The scratch space areas are for temporary file storage only. Any files stored in these areas will generally not survive a system reboot. Periodic cleaning will also be performed on older files.

Once your simulation has completed, please copy any important results back to your home directory (AFS).
