Design and implementation of a distributed system for transparent remote memory accessing

In order to improve the system memory utilization ratio and the I/O performance, we should implement distributed system of initiative to access remote memory by ways of extending swap´s capacity and improving paging speed because of the transmission characteristics of high bandwidth and low latency in high-speed LAN. In this paper, we put forward the client-the server conversion strategy which makes each node´s load balance through role judgment and service´s switching in this system. The realization of the system for applications does not require any particular API and function library. Experiments show that, for a large disk access and the application of the page exchange, the system can effectively improve overall performance.
