Journal ArticleDOI
Role of electron physics in the development of turbulent magnetic reconnection in collisionless plasmas
William Daughton,Vadim Roytershteyn,Homa Karimabadi,Lin Yin,Brian J. Albright,B. Bergen,Kevin J. Bowers +6 more
TL;DR: In this article, Petaflop-scale simulations of the evolution of turbulent magnetic reconnection in a three-dimensional plasma indicate that it proceeds in a way that is dramatically different from classical theory.
Journal ArticleDOI
Ultrahigh performance three-dimensional electromagnetic relativistic kinetic plasma simulationa)
TL;DR: VPIC has enabled previously intractable simulations in numerous areas of plasma physics, including magnetic reconnection and laser plasma interactions; next generation supercomputers like Roadrunner will enable further advances.
Journal ArticleDOI
Advances in petascale kinetic plasma simulation with VPIC and Roadrunner
Kevin J. Bowers,Brian J. Albright,Lin Yin,William Daughton,Vadim Roytershteyn,B. Bergen,Thomas J. T. Kwan +6 more
TL;DR: In this paper, a 3D electromagnetic charge-conserving relativistic kinetic particle-in-cell code was adapted to run on Los Alamos's Roadrunner, the first supercomputer to break a petaflop (1015 floating point operations per second) in the TOP500 supercomputer performance rankings.
Proceedings ArticleDOI
0.374 Pflop/s trillion-particle kinetic modeling of laser plasma interaction on Roadrunner
TL;DR: The outstanding performance and scalability of the VPIC kinetic plasma modeling code on the heterogeneous IBM Roadrunner supercomputer at Los Alamos National Laboratory is demonstrated and opens up the exciting possibility of using VPIC to model, from first-principles, an issue critical to the success of the multi-billion dollar DOE/NNSA National Ignition Facility.
Journal ArticleDOI
Onset and saturation of backward stimulated Raman scattering of laser in trapping regime in three spatial dimensions
Lin Yin,Brian J. Albright,H. A. Rose,Kevin J. Bowers,B. Bergen,D. S. Montgomery,John Kline,Juan C. Fernandez +7 more
TL;DR: Yin et al. as discussed by the authors presented a suite of three-dimensional (3D) VPIC simulations of backward stimulated Raman scattering (SRS) in inertial confinement fusion hohlraum plasma.
