A parallel virtual machine for efficient scheme compilation

Abstract

Programs compiled by Gambit, our Scheme compiler, achieve performance as much as twice that of the fastest available Scheme compilers. Gambit is easily ported, while retaining its high performance, through the use of a simple virtual machine (PVM). PVM allows a wide variety of machine-independent optimizations and it supports parallel computation based on the future construct. PVM conveys high-level information bidirectionally between the machine-independent front end of the compiler and the machine-dependent back end, making it easy to implement a number of common back end optimizations that are difficult to achieve for other virtual machines.
