On Design and Implementation of NET-RAM

  • A NVM(Network Virtual Memory) system treats all the memories distributed on the network as the memory of a single node so that an application can take the advantage of much larger memory resources on the network. This is especially suitable for such applications which are not time-sensitive but need a large amount of memories. A method of implementing a NVM system by simplifying the distributed shared memory management, which is used in our SNOW clustering system, is introduced. After giving the concept of network virtual memory, we describe the architecture of a network virtual system-NET-RAM and expatiate the structure of soft-cache. The prototype of NET-RAM is tested and the result is analyzed. Finally, we discuss our feature work to improve the NET-RAM system.
