If you have a system with multiple disk drives, is it better to keep all the paging on one disk (e.g., the disk holding the OS), or spread the paging over multiple drives? Please explain your answer.
Homework Answers
The paging should be distributed over multiple disk drives. It will help in improving the performance since the entire paging is not stored at a single location, the lookup in the table during demand loading reduces which in turn increases the performance.

21. A system has the following characteristics: Memory Access (read/write) : 50ns disk access : 20ms TLB access : 10ns TLB hit ratio : 90% page fault ratio : 5% You may assume that all page faults require a block to be written. For this system, calculate effective memory access time assuming that 2level paging is used. Show your work.

You have been tasked with a implementing a system to operate one of the first nuclear fusion power stations - a system with thousands time sensitive inputs to be monitored and act on. You are being pressured by management to adapt a single, common OS to be used throughout, e.g.. windows or linux based solely on your understanding on virtual memory what do you recommend?

Consider a demand-paging system with a paging disk that has an average access and transfer time of 20 milliseconds. Addresses are translated through a page table in main memory, with an access time of 1 microsecond per memory access. Thus, each memory reference through the page table takes two accesses. To improve this time, we have added an associative memory that reduces access time to one memory reference, if the page-table entry is in the associative memory. Assume that 80...
