| Outline of Final Research Achievements |
Methods of Auto-tuning (AT) with run-time optimization for sparse iterative library towards to exa-scale environment are developed.
(1) pXabclib, which is an MPI parallelized version of sparse iterative library Xabclib, is developed. The code is open to public. (2) Code of Sparse Matrix-vector Multiplications for GPU is implemented and evaluated with many-core CPU. Effectiveness of AT is verified by adapting Xabclib to OpenFOAM.(3) Method of 3D FDTD for electromagnetic field analysis with high frequency is studied to optimize cache access with time-space tiling without redundant computations.
