## Numerical experiments with parallel two-step W-methods for DAEs We study the numerical behavior of parallel two-step W-methods (PTSW methods) applied to index 2 and index 3 DAE test-problems. In this experiments we do not observe an order reduction in the differential components of the solution

โฆ Synopsis
In this paper, we discuss the parallel computation of the sensitivity analysis of systems of differential-algebraic equations (DAEs) with a moderate number of state variables and a large number of sensitivity parameters. Several parallel implementations based on DASSLSO are explored and their performance when using the Message Passing Interface (MPI) on an SGI Origin 2000 is compared.
