A no-line-search parallel nonlinear conjugate gradient method(NLS-PNCG) for unconstrained optimization is proposed. In this method the step length is evaluated by a fixed formula. It is shown that the NLS-PNCG requires less computation and its performance is superior to those with line search on Deep Comp 6800.
