A program's working set is the collection of segments recently referenced. This concept has led to efficient methods for measuring a program's intrinsic memory demand. It has assisted in understanding and modeling program behavior, and it has been used as the basis of optimal multiprogrammed memory management. The total cost of a working set dispatcher is no larger than the total cost of other common dispatchers. It is unlikely that anyone will find a cheaper nonlookahead memory policy that delivers significantly better *** with real programs revealed that the working set policy is the most likely to generate minimum space-time for any given program, and that one properly chosen control parameter value is normally sufficient to cause any program's working-set space-time to be within 10% of the minimum possible for that program. Working set dispatchers automatically control the level of multiprogramming while maintaining near-minimum space-time for each program.
