Managing Computational Gateway Resources with XDMoD

The U.S. National Science Foundation (NSF) has invested heavily in
research computing, funding XSEDE to integrate supercomputers with
science gateways and datasets for researchers in the U.S. and around the
world. It is important to understand how these tools contribute to
knowledge, plan wisely for future resource investments, and enable end
users to make better use of these resources. Enter XDMoD (XD Metrics on
Demand), a comprehensive tool that collects and presents detailed data
about resource usage, for program managers, developers, support staff,
and end users alike. As XSEDE adds non-traditional resources and
diversifies its computational resources, the considerable capabilities
offered by XDMoD must keep pace. In this short paper, we introduce
XDMoD's current capabilities, describe the state of its support for
gateway resources, and outline our plans to further enhance these
offerings.
