File Systems - Overview (and wquota command)

Blizzard users have access to different filesystems. Each filesystem has a special purpose and is configured to best suit this purpose.  In order to make efficient use of the resources PLEASE use the filesystems as advised below.

 

To check your quota we provide the command  "wquota".

wquota -j <project>    for project quota                  (e.g. wquota -j ab0123)
wquota -u <user>       for individual quota               (e.g. wquota -u a201123)

Filesystems  /work  and  /scratch   are optimized for fast transfer, usable for I/O intensive diagnostics and data analysis applications.
Filesystem /pf contains HOME directories.

All filesystems are  available on all nodes  (login and compute), so you can use them for inter-node communication and job chains.

 It is also possible to access your files via gridFTP.  You might like to look at our introduction to  gridFTP on blizzard.
