A Network Memory Architecture Model and Performance Analysis

Free registration required

Executive Summary

High-speed electrical circuit and optical interconnection technique bring one high-bandwidth and low-delay network. It is possible to use network memory to satisfy the memory bandwidth and capacity requirements in multiprocessor system. Previous researches have proposed that the optical interconnection technology can innovate memory architecture. This paper presents the performance study of a network memory architecture based on the idea of Dynamic Self-organized Architecture based on Grid-component (DSAG). But the long latency caused by remote memory access makes the imbalance between CPU and memory even harder, which will incur system slow-down. Most software based network memory systems were only used as network block devices and large amount of local memory were still needed.
