Abstract: This paper introduces a prototype of a multiprocessor system based on NUMA and analyzes its physical memory management in operating system. A global shared memory system is implemented based on the system, and it can allow operating system to use system-wide memory to decrease the execution time of the application. Results show that the system supports memory-intensive applications better.

Key words: cluster, loosely coupled memory management, global shared memory system
