James H. Laros III is a Distinguished Member of Technical staff at Sandia National Laboratories. Over his more than 30-year career to date, James has served the United States of America in a number of capacities beginning with four years active duty in the United States Air Force followed by a year in the Air National Guard. James continued his service as a civilian as part of the Strategic Defense Initiative program in Colorado working as a Systems Analyst. James began working at Sandia in 1995 where he has focused on various technical disciplines related to High Performance Computing (HPC) including Hierarchical Mass Storage, file-systems, systems management and systems software, Reliability Availability and Serviceability (RAS) systems and light-weight kernel operating systems. Over the past ten years James has focused on technical leadership in the area of HPC platform architecture. James currently leads many programs including: Vanguard Advanced Architecture Prototype program, Astra Chief Architect and project lead, the Alliance for Extreme Scale Computing (ACES) Crossroads lead architect and deputy program manager, and the Advanced Architecture Testbed program lead. James has won numerous awards including three R&D100 awards.
