Neil J. Gunther

from Wikipedia, the free encyclopedia

Neil J. Gunther (born August 15, 1950 in Melbourne ) is an Australian scientist specializing in Computational Information Systems ( classical and quantum systems ), physicist , teacher , musician and author , internationally known for the development of open source queuing analysis Tools "PDQ" ( Pretty Damn Quick ). He was also cited for his contribution on the theory of large transients in computer systems and network packets, as well as his universal law of computational scalability . He is currently focusing on the development of quantum information technologies .

biography

Neil Gunther was born on August 15, 1950 in Preston , Victoria , Australia . He studied chemistry , physics and applied mathematics (1976) at La Trobe University, Australia, and received his PhD in theoretical physics (1980) from the University of Southampton , England. As a research student of Prof. CJ Eliezer (one of Paul Dirac's few research students ), Gunther has Dirac number 2.

In 1980 he settled in Silicon Valley . In the following years he taught physics at San José State University (1980–1981). While he worked on the new PC technology, he worked for the Jet Propulsion Laboratory of NASA , and developed thermoelectric materials in the Voyager - and Galileo were used -space.

From 1982 Gunther worked eight years in research for Xerox PARC . There he developed the PARC bench multiprocessor - Benchmark (an early SPEC benchmark) and wrote his dissertation on Feynman's path integral . This research formed the basis of Part III of his first book The Practical Performance Analyst . Other duties at PARC included VLSI design and testing for the Dragon multiprocessor workstation ; later the SPARC center 2000 multiprocessor from Sun Microsystems emerged. In 1990 Gunther worked as a Senior Scientist and Manager for Pyramid Technology (now Fujitsu Siemens Computers ). In 1994 he founded the Performance Dynamics Company, whose clients include such well-known companies as AT&T Wireless , eBay , FedEx and Sun Microsystems . Gunther teaches worldwide (including courses at Stanford University and the University of California, Los Angeles ) and has written a variety of articles and books on performance analysis . In 1996 he was honored for the Best Technical Paper of the Computer Measurement Group and is the recipient of the AA Michelson Award 2008.

Gunther is a member of the American Mathematical Society (AMS), the American Physical Society (APS), the Association for Computing Machinery (ACM), the Computer Measurement Group (CMG), the Institute of Electrical and Electronics Engineers (IEEE), and the Institute for Operations Research and the Management Sciences (INFORMS).

Current research interests

Since 2004 Gunther has been researching quantum information systems based on photonics . During his research in this area, he developed a theory of photon bifurcation , which is currently being tested experimentally at the École polytechnique fédérale de Lausanne (EPFL).
