Pointer target tracking---an empirical study

Abstract

CONVEX ComputerCorp. has developed a language-independent interprocedural optimizer that is now available to users of its C-series supercomputers. This paper documents the benefits of one particular feature of that optiwu"zer, pointer target tracking. This paper surveys the structure of the interprocedural optimizer and the goals of pointer target tracking. It describes the realities of scientific codes that had to be handled, and gives an overview of the algorithms used. It also provides detailed statistics on the opportunities for pointer tracking, the characteristics of pointer ranges, and the bene)ts to optimization of pointer tracking.

Interprocedural Compilation of Fortran D

“…It has fostered research on aggressive optimization of scientific codes for both scalar and shared-memory machines [7]. Its pioneering work on incorporating interprocedural optimization in an efficient compilation system has also contributed the development of the Convex Applications compiler [26].…”

Interprocedural compilation of Fortran D for MIMD distributed-memory machines

“…It has fostered research on aggressive optimization of scientific codes for both scalar and sharedmemory machines [6]. Its pioneering work on incorporating interprocedural optimization in an efficient compilation system has also contributed the development of the Convex Applications compiler [26]. Through careful design, the compilation process in Parascope preserves separate compilation of procedures to a large extent.…”
