DAWRS: A Differential - Algebraic System Solver by the Waveform Relaxation Method
We investigate the concurrent solution of low-index
differential-algebraic equations (DAE’s) by the waveform
relaxation (WR) method, an iterative method for system
integration. We present our new simulation code, DAWRS
(Differential - Algebraic - Waveform Relaxation Solver), to
solve DAE’s on parallel machines using the WR methods, and
describe new techniques to improve the convergence of
such methods. As experimental results, we demonstrate the achievable concurrent performance to solve DAE’s for
a class of applications in chemical engineering.
