The login nodes (i.e., teton.arcc.uwyo.edu) support the use of SCP, SFTP, and Rsync. One may be interested in doing SSH multiplexing if often, small transfers are required when working with current SSH connections. For large files (>5GB), the Globus GridFTP software should be leveraged to move data. The Globus GridFTP software offers many advantages for transferring large data.

NFS access to the Teton cluster filesystem is available only to ARCC administered systems that reside within the data center. NFS is not provided to use computers or workstations which IT administers.

...
The ARCC Bighorn filesystem which has delivered the storage for Mount Moran for close to 5 years now is available on the Teton login nodes. The filesystem is mounted as read-only to avoid any pushing of data from Teton cluster filesystems to Bighorn. Once Mount Moran hardware is migrated to Teton, the Bighorn storage system will be repurposed, but all data will be removed from the system. It is recommended that any data that needs to be kept for extended periods of time or future computing, be migrated to the ARCC petaLibrary or into the Teton filesystems respectively.
Bighorn home
/bighorn/home
Bighorn project
/bighorn/project
Bighorn scratch
/bighorn/scratch
You can therefore use the standard "cp" command to move file from Bighorn to Teton, i.e.
cp /bighorn/home/<user id>/<some file> /home/>user id>
To move a directory and all sub-directories use:
cp -R /bighorn/home/<user id>/<some directory> /home/>user id>
As mentioned above, these filesystem are only available on the Teton login nodes and are read-only from Teton. These filesystems are not expected to be available beyond October 2018.
ARCC petaLibrary Filesystem
The ARCC petaLibrary is available from the Teton login nodes. The ARCC petaLibrary is a capacity designed system and preference is to not compute against that filesystem, but move data to the Teton cluster filesystem locations and compute, perform any data reductions and compressions, and transfer final results on the appropriate petaLibrary share. PetaLibrary allocations are by contracts only; a Teton storage space doesn't provide a petaLibrary allocation in either the homes space the homes space or the Commons space. Please see petaLibrary for more information.

Do not make symbolic links on the Teton storage to the petaLibrary or vice versa as they'll be invalid anywhere except on the Teton login nodes. |
There are two accessible points of the petaLibrary.
