Performance Tuning of Vlasov Code for Space Plasma on the K Computer

  • Conference paper

Part of the book series: Communications in Computer and Information Science ((CCIS,volume 474))

Abstract

Space plasma is a collisionless, multi-scale, and highly nonlinear medium. Thus computer simulations are essential for full understanding of space plasma. In the present study, we develop a high-performance parallel Vlasov (collisionless Boltzmann) simulation code which is the first-principle method for collisionless space plasma. The performance tuning of the code has been made on various supercomputer systems such as the K computer, FX10 and CX400 supercomputer systems. The performance efficiency of more than 15% is achieved on these systems.
