Tour of an ARCC HPC
- Lisa Stafford
Goals: Walk through accessing an ARCC HPC and navigating directories
If users have attended previous workshops, this will be review.
Opening Screen:
Shows message of the day
Lists storage usage - across project spaces
You can see this again by calling: arccquota
Also shows directories specific to arcc HPCs
General Format:[<username>@<server/node-name> <folder>]$
[arcc-t30@mblog2 ~]$ arccquota

ARCC HPC: FileSystem
Type | Location | Description | Notes |
home | /home/<username> | Personal storage space associated with user’s account. For configuration files and smaller software installations. | Smaller allocation |
project | /project/<project-name>/ | Space to collaborate among project members. Data here is persistent and is exempt from purge policy. | All project members have read/write at this level. |
project-user | /project/<project-name>/[username] | Storage specific to username within project space. Project members can read but only you may write. |
|
project-software | /project/<project-name>/software | Storage space to install software to be shared among project group members. | Only on MedicineBow |
gscratch | /gscratch/<username> | Scratch space to perform computing for individual users. | Data here is subject to a purge policy. |
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. |
