The Earth Simulator (ES) is a parallel-vector supercomputer that was developed for making precise and sound predictions of global climate and tectonic changes, and for contributing to the security and welfare of human beings. The research and development for the ES started in 1997 and was completed at the end of February, 2002. The ES consists of 640 processor nodes connected by a single-stage crossbar network, with a data transfer rate of 15 GB/s. Each node (consisting of 8 PEs) has a performance of 64 GFlops and contains 16 GB of memory. The total performance is 40 TFlops and the total memory is 10 TB.

In the middle of March the ES achieved 14.5 TFlops for an atmospheric global circulation simulation, using half of the nodes of the total system (320 nodes), which is 72.5% of the theoretical peak speed. Furthermore, in the middle of April, 35.61 TFlops was achieved for LINPACK, which corresponds to about 87% of the theoretical speed. This achievement is surprising even to us, the persons involved in the project.

The Earth Simulator is a powerful and useful asset for predicting the highly complex evolution of nature. It is indeed a magical tool that can directly contribute to the welfare of human beings. In addition, the emergence of this giant machine suggests a possible change in the thinking of us human beings, from reductionism to a new paradigm, or from ideal to real, or from simple to complex.

The presentation will include animated demonstrations of global atmospheric circulation and ocean circulation simulations obtained by the ES.

Bio: Dr. Tetsuya Sato is the Director-General of the Earth Simulator Center, Japan Marine Science and Technology Center (JAMSTEC).

The Earth Simulator Project aims to create a "virtual planet earth" on a very high performance computer, through its capability of processing a vast volume of data sent from satellites, buoys and other worldwide observation points. The system will contribute to analyze and predict environmental changes on the earth through the simulation of various global scale environmental phenomena such as global warming, El Nino effect, atmospheric and marine pollution, torrential rainfall and other complicated environmental effects. It will also provide an outstanding research tool in explaining terrestrial phenomena such as tectonics and earthquakes.

Dr. Sato has also held the positions of Professor and Director at the Theory and Computer Simulation Center, National Institute for Fusion Science, and Professor at the Graduate University for Advanced Studies.

Dr. Sato received his B.Sci., M.Sci., and Ph.D in Electronics from Kyoto University. He has a number of awards, including the Excellent JIP Award of Nikkei Science and the Tanakadate Memorial Award.

Challenges and Opportunities in Autonomic Computing

Vice President, Services and Software

IBM Research Division

Abstract: Significant advances are required to make systems more adaptive to the growing range of impulses affecting them and to reduce their total cost of management. Progress seems to require significant innovation in adaptive techniques, systems architecture, software engineering, and standards. In this presentation, I will survey the space of the requirements and draw example problems from real systems. I'll then discuss the space of our research at IBM and highlight some of the more compelling research projects we are doing in the area. I'll conclude with a summary of some key challenges for the broader community as they relate to autonomic computing.

Bio: Dr. Alfred Z. Spector is Vice President of Services and Software in IBM Research responsible for setting IBM's worldwide services and software research strategy. Recently, Dr. Spector was an Adjunct Professor at Columbia University's Computer Science Department and Senior Technical Strategist in IBM's Application and Integration Middleware (AIM) business, which has responsibility for a number of IBM software product families including CICS, WebSphere, MQSeries, and Visual Age. Previously, Dr. Spector was the General Manager of Marketing and Strategy for IBM's AIM business, and the General Manager of IBM's Transaction Systems business. Dr. Spector was also founder and CEO of Transarc Corporation, a pioneer in distributed transaction processing and wide area file systems, and a computer science professor at Carnegie Mellon University.

Dr. Spector received his Ph.D. in Computer Science from Stanford University and his A.B. in Applied Mathematics from Harvard University. Married and a father of three young children, Dr. Spector is an avid runner.

Abstract: Building HPC systems from small, cost/effective production nodes has been a favored engineering approach for many years. Technology has driven a variety of solutions over time. Today, commodity SMP nodes and interconnection networks, together with highly evolved programming models and parallel software engineering tools make a compelling combination. An overview of these topics will be presented, together with some specific solution examples. Open problems and issues will be discussed.
