Parallel solution of triangular systems of equationsThe solution on parallel computers of systems of equations Lx = b, where L is lower triangular, is considered. Some authors have suggested that it is difficult to solve such systems in parallel on message-passing, local-memory machines when L is stored by columns. It is shown here that this is not necessarily the case if the machine can accomplish fan-in communication with reasonable efficiency.
