In the get_page() function, how do we know how many pages or frames a process need?
|
| prepage

How many times should a process be prepaged? 0 ?
This is from a run on the prof's OSP.demo
Total num of pages swapped out = 532 due to page faults = 391 due to page locks set by I/O = 99 due to prepaging = 42
and this is mine: Total num of pages swapped out = 248 due to page faults = 189 due to page locks set by I/O = 59 due to prepaging = 0
If we aren't doing prepaging.. how come the .demo swaps pages due to prepaging?

no... because it could be locked more than once, so you just decrese it

does anyone's program do this? (like demo) after dispatch(pcb 0) prepageing and before dispatch(pcb 0) process dispatched, Simcore swaps in page o & 1 of pcb 0 by calling siodrum. Mine doesn't swap in anything here.

Hi prof. reed, I was wondering if you are going to post some review topics and some practice questions for the final exam. I believe u said in class that once you make the exam you will post some info regarding final exam topics and format of the exam. Thanks for your time
