Dr. Arnold’s research interests fall under the broad areas of high performance computing and large scale distributed systems. In particular, he is interested in abstractions, mechanisms and tools that allow system non-experts to harness the power of high-performance systems in scalable, efficient, reliable ways. Arnold’s research group maintains strong collaborations with the Los Alamos, Livermore, and Sandia National Laboratories -- lending them the privilege to work with world-class scientists on world-class computing systems. In part due to such collaborations, Arnold’s research projects were selected as Top 100 R&D technologies in 1999 and 2011.
