Performance portable sparse approximate inverse preconditioner for EFIE equations

Proceedings of the 2017 19th International Conference on Electromagnetics in Advanced Applications, ICEAA 2017

Bettencourt, Matthew T.; Zinser, Brian; Jorgenson, Roy E.; Kotulski, J.D.

A block base sparse approximate inverse preconditioner for the electric field integral equations is documented and tested. It utilized the Kokkos library for performance portability and shows superior performance when compared to a direct method, 36x faster for a 112K DOF problem. Furthermore, due to the abstractions available in the Kokkos library it allows one to migrate from CPU to GPU in a trivial way.
