Using the provided picture:
Assume that the processes have the following page referencing trace
Pr has P P P allocated to RAM Pg Pg P; and Pg Pg on Disk
Pr reference trace:: P P P P P P P P
Pr: Has PP allocated to memory pages PgPg and Pages Pg and on Disk
Pr page reference trace: p p p p p p p p p p p
Pr has P allocated to RAM Pg and Pg on Disk
Pr reference trace:: P P P P P
Pr: has P allocated to P
Assume that the time required to reference a page in RAM millisecondsl
And the transfer time disk to memory milliseconds.
When you need to replace a page for a particular process, always use the first page in memory which belongs to the same process; for example for Pr always replace pg; for Pr always replace pg and so on
Question:
For each process find the total execution time;
Show the final memory allocation schema.
