Program restructuring for virtual memory

by D. J. Hatfield, J. Gerald
Program reference patterns can have a more profound effect on paging performance in a virtual memory system than page replacement algorithms. This paper describes experimental techniques that can significantly reduce paging exceptions in existing, frequently executed programs. Automated procedures reorder relocatable program sectors, and computer displays of memory usage facilitate further optimization of program structure.
