We usually use Gaussian elimination algorithm to solve a dense matrix. In this method the number of operations to solve the matrix is proportional to a cube of the matrix size. Therefore, we require a large amount of computational power for large-scale problems. However, the calculations are dominated by sum-of-products operations in the forward eliminations. In the paper, we propose a system the consists of a special-purpose computer and a host computer. The special-purpose computer does only sum-of-products operations, and the host computer does all the other operations. We are developing an experimental machine of GENERAL-1 (Gaussian ElimiNation mEthod paRALlel machine).
