Optimal replacement policy, Operating System

Assignment Help:

The optimal replacement policy, called OPT, is to evict the page which will be accessed farthest into the future. Since we can't predict the future precisely, we can't implement OPT in any real system. We can, however, run OPT on a saved trace of memory accesses, to measure how our real algorithm compares with OPT for a given trace.
