Note - As of July 1st, 2016, files on scratch filesystems are subject to deletion 60 days after they were created.
User Scratch Space
Each compute node has its own local scratch filesystem. Users may read from and write to this using their own exclusive directory at /localscratch/Users/<HawkID>.
In addition to local storage, each HPC cluster has its own large, shared filesystem mounted across all its nodes via NFS. Analogously, users can read from and write to this using their own exclusive directory at /nfsscratch/Users/<HawkID>.

- change time (ctime): This is the time the metadata of the file was last changed. An example of this would be moving a file to a different directory. The change time can be seen with
ls -lc file
...
- access time (atime): This is the time the contents of the file were last accessed; for example, by viewing with 'less'. The access time can be seen with
ls -lu file
- creation time (crtime): This is the time the contents of the file were first written to the filesystem. This attribute is part of the underlying ZFS filesystem and is not accessible via NFS or standard Linux utilities.
