Research and Implementation of Single Memory Space under Clusters

In order to simplify the complexity of management and programming of clusters, this article provides a method of implementing single memory space under the clusters. It adopts hardware assisted virtualization technology of the modern mainstream processors, and combines with distributed shared memory algorithms to integrate multi-machine resources. It implements a single physical address space of COMA structure under hardware assisted strategy and unified management as well as utilization of multi-machine memory. And also the system design and implementation are described.
