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
/freezer/username
/scratch/goblin/username
/scratch/monk/username
/scratch/bul/username
/scratch/nar/username
/scratch/brown/username
/scratch/orca/scratch/username
/scratch/saw/scratch/username
/scratch/angel/scratch/username

We are working to bring requin's scratch online as well. Unlike the login nodes, file transfer apps are not limited by cpu time limits. To encourage higher throughput beyond normal scp/sftp, the following file transfer tools are available:

  1. 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 client side to make use of its extended features.
  2. Gridftp
  3. BBCP client
    • high throughput transfer tool from Stanford.

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