| Outline of Final Research Achievements |
We develop an efficient lattice QCD simulation algorithm on exa scale supercomputers. We have implemented quark solver for multiple sifts of Wilson Dirac operator with multiple right hand sides. By using this solver, we could
stably solve Wilson Dirac equations with physical quark masses. We have optimized quark solver for Xeon Phi cards and confirmed reasonable strong scaling up to 16 cards.
