Computer Science as visiting scientist, with the Architecture Group of Carlstedt Elektronik (Gothenburg, Sweden), and with Acorn Networks, Inc., as Chief Scientist. A great part of Dennis' career has been devoted to non-von Neumann models of computation, architecture, and languages, where programs are not attached to a program counter. Along with his students, Dennis adopted the concepts of single assignment and dataflow, in which instructions are executed as soon as data are available (this specific model is called "static" in contrast to Arvind's "dynamic"). In 2009, Dennis was elected a member of the National Academy of Engineering for contributions to sharing and protection in computer systems and parallel architectures based on data flow principles.

Dennis home page Biography Photograph of Jack B. Dennis Oral history interview with Jack B. Dennis at the Charles Babbage Institute, University of Minnesota. Dennis describes his educational background and work in time-sharing computer systems at the Massachusetts Institute of Technology (MIT), including the TX-0 computer, the work of John McCarthy on time-sharing, and the influence of the Information Processing Techniques Office of the Advanced Research Projects Agency. Dennis also recalls the competition between Digital Equipment Corporation, General Electric, Burroughs, and International Business Machines, to manufacture time-sharing systems. He describes the development of MULTICS at General Electric. Toward the Computer Utility: A Career in Computer System Architecture — Jack B. Dennis Parallel Computing Pioneers — Jack B.
