Architecture and realization of the modular expandable multiprocessor system MEMSY

The experimental multiprocessor system MEMSY is described. This system was built to validate the concept of a scalable multiprocessor architecture based on local shared-memory. Main application areas are scientific computations with high demand for processing power and memory capacity. In designing the hardware architecture the extensive use of standard components and fault tolerance were prerequisites. The programming model of MEMSY is custom made reflecting its true hardware structure whereas the operating system is a Unix extension.<
