Assume that there is a technique that would accelerate a linear solver and reduce the energy consumption by cutting the overall computation time. The performance of 32-bit operations is often at least twice as fast as the performance of 64-bit operations. By using a combination of 32-bit and 64-bit ﬂoating point arithmetic, the performance of many linear algebra algorithms can be signiﬁcantly enhanced while maintaining the 64-bit accuracy of the resulting solution. A code was designed and implemented for the mixed precision iterative refinement algorithm using the LU factorization with the use of the single precision and double precision. Single precision, double precision, and mixed precision iterative refinement were compared and analyzed.Not Submitted
