The Distribution of a Program in Primary and Fast Buffer Storage.

A virtual memory computer system with a fast buffer (cache) memory between primary memory and the central processing unit is considered. The optimal distribution it a program between the buffer and primary memory is studied using the program's lifetime function. Expression for the distribution of a program which maximizes the useful fraction of the cost-time integral of primary and fast buffer storage are obtained for swapping and nonswapping buffer management policies.
