The SHARCNET data transfer node (dtn.sharcnet.ca) is designed for high throughput access to Sharcnet filesystems without having to use a cluster's login node. Currently, the dtn has direct access to the following sharcnet filesystems:

/home/username
/work/username
/archive/username
/scratch/orca/username
/scratch/saw/username
/scratch/goblin/username
/scratch/monk/username
/scratch/brown/username
/scratch/iqaluk/username (also used as wobbie:/scratch)

Unlike on login nodes, file transfer processes on dtn are not limited in their CPU usage, so large transfers are possible. To encourage higher throughput beyond normal scp/sftp, the following file transfer tools are available:

HPN-SSH: PSC's modified ssh server and client that will transfer files up to 1Gb/s. You must be running hpn-ssh on the cliet side to make use of its extended features.

Gridftp: If you have a GridCanada certificate from Westgrid, then dtn.sharcnet.ca can be used directly by as a file target, or by setting up an endpoint in your Globus online account.

BBCP client: high throughput transfer tool from Stanford.

Any question on the use of dtn.sharcnet.ca can be directed to help@sharcnet.ca.

All legacy SHARCNET storage systems (/home, /work and /global/freezer) as well as remaining legacy data transfer and visualization systems (dtn.sharcnet.ca, vdi*.sharcnet.ca) will be decommissioned on April 30 2019. If you have valuable data remaining on any of these storage systems you must copy it elsewhere before April 30.

If you have not already done so we strongly recommend that you move all of your computing to the new national systems Graham, Cedar and Niagara. See this URL for help: https://docs.computecanada.ca/wiki/Getting_Started
