Determines
when a page should be brought into
|
|
|
main memory.
Two common policies:
|
|
|
|
u |
Demand
paging only brings pages
into main
|
|
|
memory when a
reference is made to a location on
|
|
the page (ie:
paging on demand only)
|
|
|
|
F |
many page faults
when process first started but
|
|
|
should decrease
as more pages are brought in
|
|
|
|
u |
Prepaging
brings in more pages than
needed
|
|
|
|
F |
locality of
references suggest that it is more
|
|
|
efficient to
bring in pages that reside
|
|
|
contiguously on
the disk
|
|
|
|
F |
efficiency not
definitely established: the extra
|
|
|
pages brought in
