Dynamic iterations for the solution of ordinary differential equations on multicore processors
In the past few years, there has been a trend of providing increased computing power through greater number of cores on a chip, rather than through higher clock speeds. In order to exploit the available computing power, applications need to be parallelized efficiently. We consider the solution of Ordinary Differential Equations (ODE) on multicore processors. Conventional parallelization strategies distribute the state space amongst the processors, and are efficient only when the state space of the ODE system is large. However, users of a desktop system with multicore processors may wish to solve small ODE systems. Dynamic iterations, parallelized along the time domain, appear promising for such applications. However, they have been of limited usefulness because of their slow convergence. They also have a high memory requirement when the number of time steps is large. We propose a hybrid method that combines conventional sequential ODE solvers with dynamic iterations. We show that it...
