Converting a swap-based system to do paging in an architecture lacking page-referenced bits
1981
ACM SIGOPS Operating Systems Review
This paper discusses the modifications made to the UNIX operating system for the VAX-11/780 to convert it from a swap-based segmented system to a paging-based virtual memory system. Of particular interest is that the host machine architecture does not include page-referenced bits. We discuss considerations in the design of pagereplacement and load-control policies for such an architecture, and outline current work in modeling the policies employed by the system. We describe our experience with
