    page replacement algoithm

    just would like to know ur opinions on this issue
    Wat page replacemtn algorithm would be best effective for a process which randomly reads 10,000 locations in its address space?

    Im thinking assuming that it is not going to be repeating pages the FIFO.. or LRU if it is likely to repeat pages..

    any thoughts would be appreciated..

    cheers

    Must be some special kind of random then

    Seems like easy homework to me
    Why don't you simulate 10K accesses to random memory locations, mapped through a simulated cache and find out how many cache misses you get with each strategy.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Well, if you are truely random (yes I know computers aren't random), i.e. you seed your random number generator with the time or something, your algorithm shouldn't matter because it is random!
