Andrew runs the SciDAC Outreach Center website, which provides software development support (source code repositories, bug trackers, etc.) for a variety of projects in the DOE's SciDAC program. Andrew has a background in development and analysis of parallel file systems, and maintains extensive file system monitoring infrastructure on the flagship computing platforms at NERSC (LMT and YAMS). Prior to joining NERSC, Andrew worked at the Lawrence Livermore National Laboratory as a developer in the Production Linux Group in Livermore Computing. Andrew received a Masters in Computer Science from SUNY Stony Brook, and a Bachelors in Physics from the University of Texas, Austin. Andrew has been with NERSC since 2007.

The Department of Energy has identified the design, implementation, and usability of file systems and archives as key issues for current and future HPC systems. This workshop addresses current best practices for the procurement, operation, and usability of file systems and archives. Furthermore, the workshop addresses whether system challenges can be met by evolving current practices.
