Monty Denneau

Monty M. Denneau ( Montague Denneau ) is a computer architect working at IBM supercomputers.

Denneau his doctorate in 1978 at the University of Illinois at Urbana -Champaign in mathematics ( about decidability in Hilbert spaces ). He developed in the early 1980s at IBM at the Thomas J. Watson Research Center ( where he has been since 1978) a special parallel computer for simulating digital computer circuits ( Yorktown Simulation Engine). Denneau remains (2013 ) on the Watson Research Center. He is the main architect of the Cyclops64 project (formerly Blue Gene / C), a parallel computer of the next generation of IBM, with a power in the petaflop range.

Cyclops should be about 1000 times faster than Deep Blue and will consist of hundreds of processors, whose 64- bit RISC instruction set has been completely rewritten. It is water cooled. An innovation is that many computing units are integrated on a chip, the operating system automatically shuts down defective units. Since therefore in the case of defects not the whole chip must always be sorted out, the Committee has been greatly reduced. The Cyclops64 chip contains 80 processors that are clocked at 500 Mhz, and each should reach 80 gigaflops. 13824 Cyclops64 such chips are connected together in parallel to the intended computer.

2002 Denneau the Seymour Cray Award received for ongoing innovative contributions to designs and implementations at the forefront of high-performance computing, which led to widely used industrial products. 2013, he was IBM Fellow.
