This Perl program uses the "hsi" command line tool to synchronize files at NERSC between local disks and the long term storage facility (HPSS).
I have installed and support a large number of software packages on a small cluster at NERSC. If you have access to this machine, you might be interested in the documentation that I have written.
My environment modules allow users to access dozens of consistently-compiled software packages on the machines at NERSC and other institutions. Many of these are CMB-specific, but there are also some tools that are useful to a more general audience.
