Abstract

To date, page management in shared virtual memory (SVM) systems has been primarily the responsibility of the run time system. However, there are some problems that are difficult to resolve efficiently at run time. Chief among these is false sharing. In this paper, a loop transformation theory is developed for identifying and eliminating page-level sharing between processors at compile-time. Loop nests of one and two dimensions (before blocking) with single-level doall style parallelism are discussed.
