Files on Bigben
File Systems
File systems are file storage spaces directly connected to a system. There are currently three such areas available to you on bigben.
- /usr/users/n/username
-
This is your home directory. The numeral 'n' will be replaced by an integer and 'username' will be replaced by your userid. You can also refer to this directory as $HOME. Your $HOME directory has a 5-Gbyte quota. $HOME is visible to all the compute nodes and all the front end nodes. $HOME is backed up daily, although it is still a good idea to store your important $HOME files to golem. Golem, PSC's file archival system, is discussed below.
You can also refer to your home directory as $TG_CLUSTER_HOME.
golem
Golem runs Cray's DMF file archival system. It is a combination tape-and-disk archival system.
The far program can be used to transfer files between golem and bigben.
You should transfer your files between golem and bigben outside of your batch jobs. Otherwise your jobs will be holding compute nodes while your files are being transferred.
If you need to store a file to golem that is 2 Tbytes or larger first contact User Services so that special arrangements can be made to store your file.
File Repositories
File repositories are file storage spaces which are not directly connected to a front end node or compute nodes. You cannot, for example, in a program open a file that resides in a file repository. You must use explicit file copy commands to move files to and from the repository. You currently have one file repository available to you on bigben: golem, PSC's file archiver.
Transferring Files
You can use kftp or scp to transfer files between bigben and your local machine. For performance reasons kftp is the preferred method. As was mentioned above, far should be used for file transfers between bigben and golem. Golem is on the TeraGrid so you can also use TeraGrid methods of file transfer between golem and your local machine. The TeraGrid is discussed below.
You can also use DMOVER to transfer your files. DMOVER is a set of programs used to schedule and execute bulk, parallel transfers of files. Extensive information about how to use DMOVER is available online. If you have questions about the use of DMOVER send email to remarks@psc.edu.-
