Please see "Using the SLAC Cluster" on the U.S. ATLAS Center at SLAC web page.
By default you get a fairly small AFS quota on your home directory. You can use the AFS Quota Self-service Form to increase your total AFS quota up to 10GB. If you run into questions, please contact the unix-admin
NFS filesystems
Dedicated ATLAS NFS spaces are available. NFS are good for log file, batch job input and output, and scratch. These NFS spaces are not backed up. So code are recommended to remain on AFS space.
- /afs/slac.stanford.edu/g/atlas/work/<firstLetterOfUsername>/<username>. (It is actually an NFS disk space)
- /nfs/slac/g/atlas/u01
- /nfs/slac/g/atlas/u02
These spaces are not automatically cleaned up.
Xrootd spaces
There are two high performance xrootd spaces - The Tier 2 space and the Tier 3 space. These space are primarily for storing ROOT files and ATLAS datasets. Creating a new file or directory on a Xrootd space takes at least 5 seconds. So they are not good for large number of small files such as logs, codes, and small text files.
