Advances in Petascale Kinetic Plasma Simulation with VPIC and Roadrunner

Speaker: Dr. Kevin Bowers, LANL

VPIC -- a first-principles 3d electromagnetic charge-conserving relativistic kinetic particle-in-cell code, was recently adapted to run on Los Alamos's Roadrunner, the first super-computer to break a petaflop (quadrillion floating point operations per second) in the TOP500 super-computer performance rankings. We summarize VPIC's modeling capabilities, VPIC's optimization techniques and Roadrunner's computational characteristics. We then discuss three applications enabled by VPIC's unprecedented performance on Roadrunner: modeling laser plasma interaction in upcoming inertial confinement fusion experiments at the National Ignition Facility NIF), modeling short-pulse laser GeV ion acceleration, and modeling reconnection in space and laboratory plasmas
