Biographical Sketch

Richard Gerber is NERSC's Senior Science Advisor to Director Sudip Dosanjh and the NERSC User Services Group Lead. Richard has been involved with leading-edge High Performance Computing systems, starting with early Cray vector systems at the National Center for Supercomputing Applications (NCSA) while earning a Ph.D. in physics from the University of Illinois at Urbana-Champaign, the Connection Machine while a National Research Council Postdoctoral Fellow at NASA-Ames Research Center, and many generations of distributed-memory parallel computers as a staff member at NERSC since 1996.

Richard used N-body/Smooth Particle Hydrodynamics codes to study colliding galaxies and equilibrium models of galaxies before coming to NERSC. At NERSC he has been at the forefront at providing scalable HPC consulting services to NERSC's users and gathering HPC needs from scientific communities and getting them implemented at NERSC. He currently leads NERSC's User Services Group,  NERSC's Programmatic Requirements Review process, oversees the highly regarded NERSC web site, coordinates NERSC's training efforts, serves as the liason to the NERSC User Group (NUG), manages NERSC's trouble ticket system, and designs and implements NERSC's annual user survey.

Richard is keenly interested in automatic collection of HPC performance and runtime data and making it available on the web to help users monitor, debug, and optimize their applications.

Richard is an expert in understanding broad science communities' needs for high performance computing, storage, and services. He and Harvey Wasserman coordinate and facilitate the  HPC Requirements Reviews for Production Computing run by NERSC, the DOE Office of Advanced Scientific Computing Research, and the DOE Office of Science program offices.

Richard was the Deputy Project Lead on the "NERSC 7" procurement of the NERSC Edison Cray XC30 system.

Richard has a Ph.D. in physics, specializing in computational astrophysics, from the University of Illinois at Urbana-Champaign. He completed a National Research Council  postdoctoral fellowship at NASA Ames Research Center. His specialty is N-body and Smoothed Particle Hydrodynamics of colliding galaxies, "ring" galaxies in particular. He has a broad interest in science and particularly in the physical sciences.

The current high-performance computing revolution provides opportunity for major increases in computational power over the next several years, if it can be harnessed. This transition from simply increasing the single-processor and network performance to a different architectural paradigms forces application programmers to rethink the basic models of parallel programming from both the language and problem division standpoints. One of the major computing facilities available to researchers in fusion energy is the National Energy Research Scientific Computing Center. As the mission computing center for DOE, Office of Science, NERSC is tasked with helping users to overcome the challenges of this revolution both through the use of new parallel constructs and languages and also by enabling a broader user community to take advantage of multi-core performance. We discuss the programming model challenges facing researchers in fusion and plasma physics in for a variety of simulations ranging from particle-in-cell to fluid-gyrokinetic and MHD models.
