Claim 15:
16. The computer program product of claim 11, wherein the program instructions to execute the process further comprise program instructions to perform at least a second iteration which comprises:
inputting the second residual vector to the array of cells;
utilizing the resistive processing unit to perform a third matrix-vector multiplication operation by multiplying the second residual vector with the preconditioning matrix in the array of cells to generate a second output vector of the plurality of output vectors;
combining the first augmented matrix with the second output vector to generate a second augmented matrix which is output from the array of cells;
performing a fourth matrix-vector multiplication operation by multiplying the second augmented matrix with a second weight vector; and
computing a third residual vector of the plurality of residual vectors based at least in part on the product of the fourth matrix-vector multiplication operation.
