TRANSFERRING FILES TO WESTGRID FROM TRIUMF

To copy large files between tw00 and the nunataks and to copy large
files between the nunataks and the compute nodes, please use the
~e614/bin/wgcp.perl wrapper for bbftp.

The wrapper is necessary because native bbftp commands are not user
friendly and are hard to use.

The wrapper knows about the special location of the remote bbftpd
server: ~e614/bin/bbftpd on e614db and on nunatak1.

The wrapper is tuned for high-speed data transfers over the WestGrid
gigabit networks. It tells bbftp to use 4 data streams with 1 Mbyte
data buffers.

The wrapper uses "ssh" to start the remote bbftpd server. When you use
it, ssh will ask for your WestGrid password, unless you have setup a
password-less ssh login.

The wrapper command is similar to "scp".  Example:

tw00% ~e614/bin/wgcp.perl run08168.ybs
nunatak1.westgrid.ca:/global/scratch/twist/olchansk/run08168.ybs 

(Note: because of a bbftp limitation, both the local and the remote
file names have to be specified. "wgcp nunatak1:file ." will not
work. You have to say "wgcp nunatak1:file file").
