Description
When transferring data in the memory between nodes using a message transfer protocol, the data copy overhead limits the data transfer bandwidth. We have implemented a user level memory to memory zero-copy data transfer protocol to avoid the data copy overhead and to increase the data transfer bandwidth. We have also employed a pin-down cache method which reuses pinned-down area to decrease the overhead of pinning-down pages to physical memory. We adapted our memory to memory zero-copy data transfer and pin-down cache method to MPI and the prototype of software distributed shared memory, and obtained a high data transfer bandwidth and a low page transfer time.
