Abstract

The computing time for the numerical solution of initial-value problems is closely related to the number of evaluations of the right-hand side. In general this number can only be reduced slightly on parallel computers, even if simultaneous evaluations of right-hand side are counted as one evaluation.

For special problems, however, it is possible to construct special methods which show a remarkable speedup on parallel computers. Multiple shooting, a method for boundary-value problems with an inherent parallelism, can also be applied efficiently to linear initial-value problems and to non-linear initial-value problems if good approximations are available.

      Very early ideas go back to the 1960’s [2,3]. In the 1980’s and 1990’s, parabolic and space–time multigrid methods [4,5] and parallel multiple shooting for initial value problems [6] were studied. A more recent and today very widely studied method is Parareal [7], which is also the method this paper is concerned with.

      But the time dimension is much harder to deal with due to its inherently sequential nature. There have been several attempts at temporal parallelization in the last decades [1–3]. The parareal technique, a recently developed algorithm [4], has been shown to be a very promising option.
