Those double speed ALU's were the dumbest CPU idea I have heard of yet, and were conceived by someone lacking a basic understanding of CPU performance.

I wonder if they had to use all low Vt devices in this ALU in order to achieve the doubled speed. That would certainly produce a localized hot spot. Typically low Vt devices in use that I have seen can have 20% higher drive currents but easily 10x more off current. Intel's implementation might have gone beyond even that. Their use must be limited. I know this is the first generation in which Intel starting using low Vt devices and maybe they got carried away. Also, these devices are much more susceptible to process variations resulting in more chip/chip wafer/wafer and lot/lot variations. That might also explain the variability of the effect seen from processor to processor. Do you know how much real estate (how many devices) would be involved in these double speed ALUs?

AMD Athlon Processor Gaining Global Recognition as Supercomputing Superstar
NASA, National Science Foundation-funded university research programs in the U.S., universities in Hong Kong and Japan employ AMD Athlon(TM) processor-based supercomputers
SUNNYVALE, Calif.--(BUSINESS WIRE)--May 17, 2001-- AMD today announced that five more academic institutions have each installed new supercomputers using the award-winning AMD Athlon(TM) processor. Cited for their powerful performance, scalability, and flexibility to expand in a cluster environment, a series of AMD Athlon processor-based supercomputers have been employed for research programs at the Hong Kong University of Science & Technology, the Tokyo Institute of Technology, a National Aeronautics and Space Administration (NASA) funded program at the University of California at Santa Cruz (UCSC), as well as National Science Foundation (NSF) funded programs at Western Michigan University and Calvin College. These wins demonstrate how the AMD Athlon processor is continuing to expand its reputation as a powerful, innovative and reliable solution for supercomputing platforms used for scientific research.
``This once again proves our AMD Athlon processor is a great choice for cutting-edge computer platforms targeted for computation-intensive applications created by academic researchers,'' said Ed Ellett, vice-president of Workstation and Server Marketing for AMD. ``As the need for increased performance and bandwidth continues, we are committed to developing more powerful processors to meet that challenge. We eagerly look forward to supporting critical research projects with leading academic institutions around the world.''

The Hong Kong University of Science & Technology, one of the most prestigious higher education institutions in Hong Kong, has developed a supercomputer featuring 80 AMD Athlon processors.

``This AMD processor-based cluster provides a powerful tool for the advancement of scientific research,'' says Associate Professor P W Leung of HKUST's Physics Department. ``We can perform realistic simulations, design advanced composite materials through accurate modeling, and also tackle the most challenging problems in modern material physics involving complex materials where the electronic states are strongly correlated.''

The Tokyo Institute of Technology, one of the most prestigious higher education institutions in Japan, has built the PRESTO III, a 78 AMD Athlon processor-based cluster that will be employed at the Matsuoka Laboratory of the Global Scientific Information and Computing Center & Department of Mathematical and Computing Sciences.

``The objective of the PRESTO series of Grid clusters project is to enable cost-effective solutions to empower the computational Grid, investigate effective software used for commodity clustering, and conduct simulation and application studies on the Grid for various scientific applications such as operations research, high energy physics, and neuroscience,'' said Professor Satoshi Matsuoka of the Tokyo Institute of Technology. ``We want to thank the sponsors of Japan's national PRESTO program of the Japan Science and Technology Corporation (JST), and AMD for its processor technology.''

The National Aeronautics and Space Administration (NASA) has helped fund a 32 AMD Athlon processor-based cluster node supercomputer located at UCSC. The UCSC supercomputer, developed and built by Racksaver, Inc. through the assistance of Dolphin Interconnect, will be used to study collisional processes in the solar system, and run simulations of planetary dynamos, such as the one responsible for Earth's magnetic field.

``The university's Earth Sciences, Astronomy and Physics departments now have the ability to solve complex research problems 24 hours a day, seven days a week on our own local research cluster,'' said Erik Asphaug, UCSC principal investigator of the new 32-node research supercomputer. ``Also, we can now create, archive, and visualize our data locally, and this removes the data bottlenecks and enhances our student's educational environment.''

Another 32-node supercomputer has been installed at the ParInt Research Group at Western Michigan University under an NSF-funded grant. ``Very early on in our purchasing decision process we decided to go with AMD Athlon processors, for their performance and pricing, and we have not been disappointed,'' said Elise de Doncker, Professor in the Computer Science department at Western Michigan University. ``The cluster has been very reliable and invaluable to our research efforts in parallel numerical integration, and for class projects in various advanced computer science courses.''

``The Department of Computer Science at Calvin College is committed to providing its students with hands-on experience using cutting-edge technologies, including high performance computing,'' said Joel Adams, Professor of Computer Science, Calvin College in Grand Rapids, Michigan, the location of an 18 AMD Athlon processor-based cluster. ``The cluster will also greatly benefit our faculty researchers in their individual research programs. We are grateful to the National Science Foundation, NFP Enterprises, and AMD for their help in making this a successful project.''

This trend follows AMD Athlon processor-based supercomputers already installed in the University of Delaware, the University of Kentucky, and the University of Utah, and reflects a growing number of universities obtaining and benefiting from the use of powerful supercomputer systems based on AMD processor technology. Each of these systems employ the Beowulf Cluster design architecture, which involves connecting each processor in parallel to maximize speed and processing power while providing inter-communications between the processors and compute nodes, and use a Linux-based operating system.
