  The Gauge Connection at qcd.nersc.gov is one of the most popular repositories
of QCD lattice ensembles. It is used to access 16TB of archived QCD data from
the High Performance Storage System (HPSS) at the National Energy Research
Scientific Computing Center (NERSC). Here, we present a new web interface for
qcd.nersc.gov which allows physicists to browse and search the data, as well as
download individual files or entire ensembles in batch. Our system
distinguishes itself from others because of its ease of use and web based
workflow.
