Numerical Experiments with Some Explicit Pseudo Two-step Rk Methods on a Shared Memory Computer
This paper investigates the performance of two explicit pseudo two-step Runge-Kutta methods of order 5 and 8 for rst-order nonstii ODEs on a parallel shared memory computer. For expensive right hand sides the parallel implementation gives a speedup of 3{4 with respect to the sequential one. Furthermore we compare the codes with the two eecient nonstii codes DOPRI5 and DOP853. For problems, wher...
متن کاملPerformance of explicit pseudo two - step RKNmethods on a shared memory computer
The aim of this paper is to investigate the performance of two explicit pseudo two-step RKN methods (EPTRKN methods) of order 6 and 10 for nonstii problems y 00 (t) = f(t;y(t)), y(t 0) = y 0 , y 0 (t 0) = y 0 0. For expensive problems, the parallel implementation on a shared memory computer gives a good speed-up with respect to the sequential one. Furthermore, for numerical comparisons, we solv...
متن کاملExplicit parallel two-step peer methods
The construction of s-stage explicit parallel two-step peer methods for the solution of non-stiff initial value problems with optimal zero stability and order p = s is considered. By an additional condition superconvergence of order p = s + 1 can be achieved. Further criteria for good methods are large stability regions and small error constants. Corresponding parameter sets have been obtained ...
متن کاملA NEW TWO STEP CLASS OF METHODS WITH MEMORY FOR SOLVING NONLINEAR EQUATIONS WITH HIGH EFFICIENCY INDEX
It is attempted to extend a two-step without memory method to it's with memory. Then, a new two-step derivative free class of without memory methods, requiring three function evaluations per step, is suggested by using a convenient weight function for solving nonlinear equations. Eventually, we obtain a new class of methods by employing a self-accelerating parameter calculated in each iterative...
متن کاملA Class Of Implicit-Explicit Two-Step Runge-Kutta Methods
This work develops implicit-explicit time integrators based on two-step Runge-Kutta methods. The class of schemes of interest is characterized by linear invariant preservation and high stage orders. Theoretical consistency and stability analyses are performed to reveal the properties of these methods. The new framework offers extreme flexibility in the construction of partitioned integrators, s...
