An efficient application of computational systems equipped with Intel Xeon Phi
coprocessors for the laser-plasma simulation is considered. The features of
Xeon Phi architecture that influence the performance of Particle-in-Cell plasma
simulation are analyzed. The PICADOR parallel plasma simulation code previously
optimized for Xeon Phi is described. Its performance on Xeon Phi compared to CPU
is studied on three computationally intensive plasma simulation problems. The ratio
of computational time on Xeon Phi to CPU is discussed for the main stages of the
Particle-in-Cell method. It is shown that, depending on the features of a physical
problem, the use of Xeon Phi can be both advantageous and disadvantageous compared
to CPU.
Keywords: plasma physics, particle-in-cell method, high-performance computing,
Xeon Phi, performance optimization.
