An Integer Arithmetic-Based Sparse Linear Solver Using a GMRES Method and Iterative Refinement

Takeshi Iwashita, Kengo Suzuki, Takeshi Fukaya

In this paper, we develop a (preconditioned) GMRES solver based on integer arithmetic, and introduce an iterative refinement framework for the solver. We describe the data format f…
