Parallel programming using the MMX operating system and its processor

MMX (multiprocessor multitasking executive) is a small yet powerful operating system for shared memory multiprocessors. The MMX parallel processor is a small shared bus multiprocessor assembled from several commercial processor boards. Together, MMX and its parallel processor provide a flexible and powerful testbed for parallel software development. The author describes MMX design principles, its structure and services. Parallel programming techniques with MMX are demonstrated with special emphasis on work distribution. The author concludes with some MMX timing and speedup measurements of several parallel programs.<>
