Funding a faster supercomputer.Getting a group of people to work together efficiently is a demanding task that often requires a skilled manager. Computer designers and programmers are now looking for Looking for In the context of general equities, this describing a buy interest in which a dealer is asked to offer stock, often involving a capital commitment. Antithesis of in touch with. the electronic equivalent of such a manager to cope with "multiprocessor" computers. Each of the many processors built into this type of computer can independently retrieve data from memory locations, do arithmetic operations like addition or perform other simple operations. Yet the computer must quickly come up with a "consensus"--a single, correct answer. Last week, the Department of Energy (DOE) and the National Science Foundation awarded grants totaling $9 million to the University of Illinois at Urbana-Champaign Early years: 1867-1880 The Morrill Act of 1862 granted each state in the United States a portion of land on which to establish a major public state university, one which could teach agriculture, mechanic arts, and military training, "without excluding other scientific to pursue this problem. David Kuck Professor David J. Kuck, while at the University of Illinois at Urbana-Champaign, is a computer scientist who led the CEDAR project, a hierarchical shared-memory a 32-processor SMP supercomputer completed in 1988. , director of the university's new Center for Super-computing Research, and his colleagues plan to build an experimental supercomputer, called the "Cedar" system, to test their ideas. The problem is to connect the computer hardware and software in such a way that all the multiprocessing occurs in an organized, productive and fast way, says Kuck. This project is unusual because, to achieve high speeds, it relies on clever ways of linking the processors and then writing computer programs that take advantage of these arrangements rather than on advances in computer chip technology. DOE also helps fund two other large supercomputing research programs. At the California Institute of Technology California Institute of Technology, at Pasadena, Calif.; originally for men, became coeducational in 1970; founded 1891 as Throop Polytechnic Institute; called Throop College of Technology, 1913–20. in Pasadena, Charles L. Seitz, Geoffrey Fox and their colleagues aim to build a computer that fits on a desktop but still has 50 times the power of a Cray-1 supercomputer at a fraction of the Cray's current price. The researchers already have one experimental machine, completed last October and dubbed "The Cosmic Cube," in which 64 identical microprocessors are connected in a communications network based on a six-dimensional cube. At New York New York, state, United States New York, Middle Atlantic state of the United States. It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of University's Courant Institute of Mathematical Sciences The Courant Institute of Mathematical Sciences (CIMS) is a division of New York University (NYU) and serves as a center for research and advanced training in computer science and mathematics. in New York City New York City: see New York, city. New York City City (pop., 2000: 8,008,278), southeastern New York, at the mouth of the Hudson River. The largest city in the U.S. , researchers are working on the "ULTRAcomputer" project. In this "dataflow" computer, hundreds of thousands of processors share one massive memory, communicating with it through a switching network that keeps the processors synchronized. Instead of searching the memory for the data needed to do a certain computation, each processor patiently waits until the essential bits of data arrive so that it can do its job (SN: 6/16/84, p. 378). |
