Virtual Memory Management in the VAX/VMS OS Henry Levy and
One-line summary: This paper presents a virtual memory system intended
to run with low overhead and I/O on a wide variety of hardware configurations.
RelevanceThis paper presented a virtual memory system with three
important mechanisms that improved performance:
- Caching of pages to reduce disk I/Os for pages recently removed from a
process's resident set.
- Clustering (simulates the efficientcy of larger page transfers).
- Process-local replacement, to reduce the effect of process' paging
activities on each other.
- Lack of statistics/numbers. More info on how the system performed under
different loads and resident set sizes would have been useful.
