Barney Maccabe currently serves as the Director for the Computer Science and Mathematics Division at Oak Ridge National Laboratory (ORNL). The division has over 100 technical staff conducting research in a wide range of areas, including computational and applied mathematics; discrete systems; data analysis, visualization, management, and engineering; programming models, and tools; performance modeling, measurement, and analysis; system software; and emerging technologies. Prior to joining ORNL in January of 2009, Dr. Maccabe served on the Computer Science faculty at the University of New Mexico where he also served as director of the UNM Center for High Performance Computing and the CIO for the university. As a professor, he graduated 11 PhDs and 9 Masters working in the general area of computing systems. Much of his work has focused on the research related to lightweight approaches in HPC systems. Working in collaboration with staff at Sandia National Laboratories, he was involved in the design and development of a series of lightweight operating systems, starting with SUNMOS (Sandia-UNM OS) for the Intel Paragon back in 1990. This collaboration has grown over the years to include a large collection collaborators with a current emphasis on lightweight virtualization technologies aimed at supporting application composition in HPC system.
Barney earned his BS in Mathematics from the University of Arizona in 1977 and his MS and PhD in Information and Computer Sciences from the Georgia Institute of Technology in 1980 and 1982, respectively.
