Convergent iterative schemes for time parallelization [PDF]
Mathematics of Computation, 2006 Summary: Parallel methods are usually not applied to the time domain because of the inherit sequentialness of time evolution. But for many evolutionary problems, computer simulation can benefit substantially from time parallelization methods. In this paper, we present several such algorithms that actually exploit the sequential nature of time evolution
