Home Directories
Each user is provided a home directory to store frequently used items such as source code, binaries, and scripts. Please see the home directories page in the general support section for more details.
Project Directories
Each project is provided a directory to share project common files. Please see the project directories page in the general support section for more details.
Work Directories
A large work area is available on each Verne node for temporary files and for staging large files from and to the High Performance Storage System (HPSS). This temporary space is not backed up. Thus, it is critical to archive files from the scratch area as soon as possible. Also note that Verne is to be used for analysis (post-processing and visualization). Batch jobs cannot run across nodes on Verne.
Each user’s work space can be accessed through the following environment variable:
$TG_NODE_SCRATCH
In a batch job context, this directory is only guaranteed to exist for the duration of the job, so it is important that jobs be configured to stage any results out to either HPSS or the user's home directory.
Work is currently in progress to add a shared work area to Verne.
There is more detailed information regarding preferred methods for transferring files” from kraken to verne in the Data Transfer section.
Further description of $TG_NODE_SCRATCH and other standard Teragrid environment variables can be found at http://www.teragrid.org/userinfo/jobs/variables.php.
HPSS
The HPSS provides archival storage for NICS users. Please see the HPSS section for more details.
