On page blocks in distributed virtual memory systems

We introduce the concept of working set-based page block in distributed virtual memory systems. We show that hit ratio is significantly better than that of conventional systems, where page blocks are formed from neighboring contiguous pages on the disk. Moreover, the choice of some relevant virtual memory parameters, which is usually made by the system manager and is riskier and may affect the efficiency of the system. We show that such choice becomes more reliable by using page blocks.
