Q. Consider the two-dimensional array A:
int A[][] = new int[100][100];
Whereas A [0][0] is at location 200 in a paged memory system with pages of size 200. A little process is in page 0 (locations 0 to 199) for manipulating the matrix thus every instruction fetch will be from page 0.
For three page frames how various page faults are generated by the following array-initialization loops using LRU replacement and assuming page frame 1 has the process in it and the other two are initially empty?
a.
for (int j = 0; j < 100; j++)
for (int i = 0; i < 100; i++)
A[i][j] = 0;
b.
Answer:
a. 50
b. 5,000
