Porting and Verification of ExaFMM Library in MIC Architecture

ExaFMM is a highly scalable implementation of the Fast Multipole Method (FMM) – an O(N) algorithm for solving N-body interaction with applications in gravitational and electrostatic simulations. The authors report scaling on large systems with O(100k) cores with support for MPI, OpenMP and SIMD vectorization. The library also includes GPU kernels capable of running on a multi-GPU system. The objective of the project is to enable the use of the ExaFMM solver in the MIC architecture by performing porting, verification, scalability testing and providing configuration suggestions to its potential users
