Abstract :
In this paper, we are concerned with a parallel iterative method for nonlinear least-squares problems, which can be viewed as an alterative ordering of the variables in the Jacobian method, the variables are divided into non-disjoint groups. Furthermore, a parallel algorithm is proposed and performed on HP-SPP1600. The numerical results show that the algorithm has nice speedup and parallel efficiency.
