Performance analysis of two address space allocation schemes for an optically interconnected distributed shared memory system

An Optically Interconnected Distributed Shared Memory (OIDSM) system is introduced and analyzed. Distributed shared memory systems place a heavy traffic requirement on the interconnection network. Complex memory allocation schemes have been introduced to reduce the network load. The photonic network of the system introduced in this paper alleviates the traffic load concern, and enables the development of a fixed memory allocation scheme with a significant reduction in complexity. The photonic network employs wavelength division multiple access (WDMA), creating multiple channels on a single optical fiber. This paper analyzes the performance of two memory allocation schemes through mean value analysis of a closed queueing network. The performance model is validated through simulation.<>
