Interaction Between Compilers And Computer Architectures

Effective compilers allow for a more efficient execution of application programs for a given computer architecture, while well-conceived architectural features can support more effective compiler optimization techniques. A well thought-out strategy of trade-offs between compilers and computer architectures is the key to the successful designing of highly efficient and effective computer systems. From embedded micro-controllers to large-scale multiprocessor systems, it is important to understand the interaction between compilers and computer architectures. The goal of the Annual Workshop on Interaction between Compilers and Computer Architectures (INTERACT) is to promote new ideas and to present recent developments in compiler techniques and computer architectures that enhance each other's capabilities and performance. Interaction Between Compilers and Computer Architectures is an updated and revised volume consisting of seven papers originally presented at the Fifth Workshop on Interaction between Compilers and Computer Architectures (INTERACT-5), which was held in conjunction with the IEEE HPCA-7 in Monterrey, Mexico in 2001. This volume explores recent developments and ideas for better integration of the interaction between compilers and computer architectures in designing modern processors and computer systems. Interaction Between Compilers and Computer Architectures is suitable as a secondary text for a graduate level course, and as a reference for researchers and practitioners in industry.

This text presents information on architecture and parallel and high-performance computing presented at the 6th Workshop on Interaction between Compilers and Computer Architecture (INTERACT 2002).

In brief summary, the following results were presented in this work: • A linear time approach was developed to find register requirements for any specified CS schedule or filled MRT. • An algorithm was developed for finding register requirements for any kernel that has a dependence graph that is acyclic and has no data reuse on machines with depth independent instruction templates. • We presented an efficient method of estimating register requirements as a function of pipeline depth. • We developed a technique for efficiently finding bounds on register require ments as a function of pipeline depth. • Presented experimental data to verify these new techniques. • discussed some interesting design points for register file size on a number of different architectures.

INTERACT 2004 presents new ideas and explores recent developments in compiler techniques and computer architectures that enhance each other's capabilities and performance. Its papers cover various aspects of interaction between compilers and architectures in the design of high-performance microprocessors, embedded controllers, multiprocessors, and other parallel computer systems.
