To aid users in the transfer of files between the Tri-Lab sites, there are tools available on each site's data transfer cluster (LLNL's cslic cluster, LANL's redcap cluster and SNL's lynxs cluster. The tools provide access to a remote site's HPSS (for file system to archive transfers) or to a remote site's data transfer cluster (for file system to file system transfers).

The diagram below lists the names of the tools available and illustrates the target connection.
