File Systems & Software

https://www.nas.nasa.gov/hecc/support/kb/filesystems-software-99/

The quota for the home directory at NAS is usually quite small. Indeed, it may not even hold a build of GEOSgcm. So, we recommend building doing most work in nobackup or other project directories. This page details how to see your current quota
