Fijany, Amir, 1993, "Fast Time and Space Parallel Algorithms for Solution of Parabolic Partial Differential Equations", https://hdl.handle.net/2014/34955, USA, JPL Open Repository
In this paper, fast time- and Space -Parallel agorithms for solution of linear parabolic PDEs are developed. It is shown that the seemingly strictly serial iterations of the time-stepping procedure for solution of the problem can be completed decoupled. |
