Multigrid is widely used as an efficient solver for sparse linear systems arising from the discretization of elliptic boundary value problems. Linear relaxation methods like Gauss-Seidel and Red-Black Gauss-Seidel form the principal computational component of multigrid, and thus affect its efficiency. In the context of multigrid, these iterative solvers are(More)
In this paper, we explore some of the new opportunities for distributed collaborative applications that emerge from the use of XML as a data specification language. We present two different approaches: the first one transparently adds asynchronous collaboration to applications whose persistent state is in XML format, while the second one helps build(More)
