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.
