Revisiting the Gauss-Huard Algorithm for the Solution of Linear Systems on Graphics Accelerators
(Springer, 2016-04-02)
In 1979, P. Huard presented an efficient variant of the Gauss-Jordan elimination for the solution of linear systems. In particular, this alternative algorithm exhibits the same computational cost as the traditional LU-based ...
A Parallel Multi-threaded Solver for Symmetric Positive Definite Bordered-Band Linear Systems
(Springer, 2016-04)
We present a multi-threaded solver for symmetric positive definite linear systems where the coefficient matrix of the problem features a bordered-band non-zero pattern. The algorithms that implement this approach heavily ...
