This paper is concerned with an accurate computation of matrix multiplication. Recently, an accurate summation algorithm was developed by Rump, Ogita and Oishi. One of the key techniques of their method is a new type of error-free splitting. To use this strategy, we investigate a method of obtaining an accurate result of matrix multiplication by mainly using Level 3 BLAS operation. Finally, we present numerical examples showing the e ectiveness of the proposal algorithm.
