2481	 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 of a program between the buffer and primary memory is studied using the program s lifetime function. Expressions 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. cache virtual memory lifetime function cost-time integral fast buffer
