Network Memory

This project deals with exploting the idle main memory of all workstations in a LAN. Such uses of that available main memory include, remote memory paging, network RAM disk, (remote) main memory database systems, etc. Fast interconnection networks enable fast memory-to-memory transfers, thus making paging to remote memory more promising than paging to disk.
