If users have attended previous workshops, this will be review.

ARCC HPC: FileSystem
Type | Location | Description |
home | /home/<username> | Space for configuration files and software installations. |
project | /project/<project-name>/[username] | Space to collaborate among project members. Data here is persistent and is exempt from purge policy. |
gscratch | /gscratch/<username> | Space to perform computing for individual users. Data here is subject to a purge policy defined below. |
node local scratch | /lscratch | Only on compute. |
memory filesystem | /dev/shm | RAM-based tmpfs available as part of RAM for very rapid I/O operations; small capacity. |
