“…This sheath is formed by hot electrons accelerated to relativistic energies by laser field at front surface of the target. One of the main problems of the scheme is its low efficiency [5]. Recently, it has been suggested to use surface grating on the irradiated size of the target to increase laser-electron coupling and therefore increase amount of energy transferred from laser radiation to ions [28].…”

“…This is valuable for both fundamental research on physics of matter in extreme conditions and various applications. The notable directions are: laser-driven electron acceleration to the ultrarelativistic energies [3], acceleration of ion beams to tens and hundreds MeV / nucleon [4,5], generation of X-ray and gamma ray radiation including pulses of atto-and zeptosecond duration [6], and QED effects in ultrahigh intensity field, namely electron-positron pair production and nonlinear optics of vacuum [7,8]. The applications are fast ignition of inertial confinement fusion targets [9], hadron therapy for cancer treatment [10], protonography, xray imaging [11], etc.…”

a b s t r a c tThis paper concerns the development of a high-performance implementation of the Particle-in-Cell method for plasma simulation on Intel Xeon Phi coprocessors. We discuss the suitability of the method for Xeon Phi architecture and present our experience in the porting and optimization of the existing parallel Particle-in-Cell code PICADOR. Direct porting without code modification gives performance on Xeon Phi close to that of an 8-core CPU on a benchmark problem with 50 particles per cell. We demonstrate step-by-step optimization techniques, such as improving data locality, enhancing parallelization efficiency and vectorization leading to an overall 4.2× speedup on CPU and 7.5× on Xeon Phi compared to the baseline version. The optimized version achieves 16.9 ns per particle update on an Intel Xeon E5-2660 CPU and 9.3 ns per particle update on an Intel Xeon Phi 5110P. For a real problem of laser ion acceleration in targets with surface grating, where a large number of macroparticles per cell is required, the speedup of Xeon Phi compared to CPU is 1.6×.

This paper presents experimental results of Particle-in-Cell plasma simulation on a hybrid system with CPUs and Intel Xeon Phi coprocessors. We consider simulation of two relevant laserdriven particle acceleration regimes using the Particle-in-Cell code PICADOR. On a node of a cluster with 2 CPUs and 2 Xeon Phi coprocessors the hybrid CPU + Xeon Phi configuration allows to fully utilize the computational resources of the node. It outperforms both CPU-only and Xeon Phi-only configurations with the speedups between 1.36 x and 1.68 x.
