GP5: A Software Layer for Portable Parallel Program Development

摘要

The technical memorandum describes a strategy for developing portable parallelprograms to dramatically reduce the costs of moving these programs among massively parallel processor (MPP) systems. The central component of the strategy is a software layer (GP5) now under development. This layer is designed to insulate the parallel program developer from vendor-specific issues, allowing uniform expression of parallel constructs on all target machines. The layer will be portable to a wide range of MPP and UNIX platforms with minimal effort. Programs written using the layer will run on any target machine without modification of source code.
