Indirect equation solvers such as the conjugate gradient method have been successfully vectorized and are capable of efficiently solving very large three-dimensional nonlinear static problems. A further reduction in job turn around time may be accomplished with concurrent vector processing computers. The nonlinear conjugate gradient algorithm is adapted to concurrent vector processing computers while striving to preserve the vector processing speed of the algorithm. It is critical that the nonlinear capabilities of the code are still efficiently processed under the concurrent algorithm. The algorithmic performance for two highly nonlinear three-dimensional problems is discussed. 7 refs., 4 figs.
