Progress toward a parallel MAGIC

Summary form only given, as follows. MAGIC is an electromagnetic particle-in-cell code. MAGIC uses the finite-difference time-domain method to support simulations of both two- and three-dimensional geometries with a wide variety of diagnostics and models for outer boundaries, material properties and emission processes. The greater availability of parallel computing platforms has generated interest in a parallel version of MAGIC to enable larger simulations. We are proceeding with an incremental approach to parallelization of MAGIC. An incremental approach will gradually improve the efficiency of the parallel implementation while maintaining the full capability of the MAGIC code. We discuss the recent progress made in implementing loop-level parallelism in MAGIC using OpenMP. OpenMP has been chosen because it permits initial loop-level parallelism while also providing for task-level parallelism in the future. We also outline future plans for improved parallel execution using domain decomposition of the simulation grid and particles.
