This paper investigates the implementation of the page
fault frequency (PFF) replacement algorithm as the mechanism
for selecting and replacing pages of programs loaded into
the main memory of a multiprocessing, multiprogrammed
computer system. The frequency at which an executing
program requires a page of virtual memory, the PFF, provides
a basis for judging the real memory requirements of the
program. Operating difficulties of PFF that reduce its
usefulness in a time-shared computer system (Michigan
Terminal System) are discussed, and a means of implementing
the algorithm is proposed.http://archive.org/details/implementationof00lancCaptain, United States Marine CorpsApproved for public release; distribution is unlimited
