Buttari et al. have proposed the mixed-precision iterative refinement method using the IEEE754 single- and double-precision arithmetic for solving linear systems of equations. Their benchmark tests show that their proposed method can obtain high performance on computation environment on which the performance of single-precision arithmetic can be higher than double-precison arithmetic. However, ...
Buttari et al. have proposed the mixed precision iterative refinement using the IEEE754 single and double precision arithmetic for solving linear systems of equations. We broaden the scope of applications of the mixed precision iterative refinement by using a combination of double precision arithmetic and multiple precision arithmetic, and show that the new method has higher performance and yie...
