Abstract :
We outline an algorithm for block-sparse GPU accelerated out-of-core solver. The algorithm takes advantage of the block-sparsity that exists in method of moment analysis of composite electromagnetic systems with multiple materials. The efficiently of the proposed algorithm is demonstrated on the example of Luneburg lenses up to 40 wavelengths diameter. The approach yields speedup of up to 8 times, compared to general-purpose GPU accelerated out-of-core solver.
