Abstract

Scientific and engienering applications often involve structured meshes. These meshes may be nested (for multigrid or adaptive codes) and/or irregularly coupled (called Irregularly Coupled Regular Meshes). We have designed and implemented a runtime library for parallelizing this general class of applications on distributed memory parallel machines in an efficient and machine independent manner. In this paper we present how this runtime library can be integrated with compilers for High Performance Fortran (HPF) style parallel programming language. We discuss how we have integrated this runtime library with the Fortran 90D compiler being developed at Syracuse Universisty and provide experimental data on a block structured Navier-Stokes solver template and a small multigrid example parallelized using this compiler and run on an Intel iPSC/860. We show that the compiler parallelized code perrforms within 20% of the code parallelized by inserting calls to the runtime library manually.
