We are now developing a manycore-aware implementation of multiprocessed PIC (particle-in-cell) simulation code with automatic load balancing. A key issue of the implementation is how to exploit the wide SIMD mechanism of manycore processors such as Intel Xeon Phi. Our solution is "particle binning" to rank all particles in a cell (voxel) in a chunk of SOA (structure-of-arrays) type one-dimensional...
This paper investigates the scalability of a parallel fast multipole accelerated boundary integral equation method in electrostatic field analyses. A load balancing technique suitable for highly parallel computation with 100 or more processes is also proposed. Numerical results clarify the effectiveness of the developed method in practical models with complicated geometry.
