		Abstract

We have developed software tools for composite-grid methods. The tools
facilitate the programming of PDE solvers on structured composite
grids. They raise the level of abstraction which makes the code easier
to read, modify and maintain. Moreover, the tools are
parallelized in SPMD-style. Code written with the
tools become portable over a wide range of computers. We have
implemented a Navier-Stokes solver and
executed the code on a SUN Sparc 10, IBM SP2, and Intel Paragon XP.
