The IEEE Computer Society is your resource for information on computing. Celebrating its 55th anniversary in 2001, it is the oldest and largest association of computer professionals in the world. It offers over 100,000 members a comprehensive program of publications, meetings, and technical and educational activities, fostering an active exchange of information, ideas, and innovation. The society is the world's leading publisher of technical material in the computing field. Headquartered in Washington, DC, the society serves its members from offices in Los Alamitos, CA; Tokyo, Japan; and Brussels, Belgium. The society is the largest technical society within the Institute of Electrical and Electronics Engineers (IEEE). For more information, please contact: The Association for Computing Machinery (ACM), the First Society in Computing, is a major force in advancing the skills and knowledge of information technology professionals and students throughout the world. ACM serves as an umbrella organization offering its 90,000 members a variety of forums in order to fulfill its members' needs--the delivery of cutting-edge technical information, the transfer of ideas from theory to practice, and opportunities for information exchange. Providing high-quality products and services--world-class journals and magazines, dynamic special interest groups, numerous "main event" conferences, tutorials, workshops, local special interest groups and chapters, and electronic forums--ACM is the resource for lifelong learning in the rapidly changing field of information technology.

Special Interest Group on Computer Architecture (SIGARCH) serves a unique community of computer professionals working on the forefront of computer design in both industry and academia. It is ACM's primary forum for interchange of ideas about tomorrow's hardware and its interactions with compilers and operating systems. The SIG's focus area is the architecture of computer systems, including all aspects of their organization, structure, design, and engineering. Special interest areas include: physical structure of computer systems, organization of processors (superscalar, multithreaded), memory hierarchies, disks and I/O organizations, control and sequencing (dynamic and static scheduling, speculative execution), shared-memory multiprocessors, multicomputers, distributed shared memory systems.
