Abstract: The combined RK-Rosenbrock(CRKR) methods are presented for a partitioned systems of stiffly large differential equations.Nonstiff and stiff subsystems are integrated in parallel on two processors by an explicit RK method and a Rosenbrock method respectively.Their construction,convergence and numerical stability are studied,and the numerical simulation experiments are conducted on a personal computer and a parallel computer.

Key words: multicomputer system, stiffly large system, combined methods
