UNIVERSITY OF HERTFORDSHIRE COMPUTER SCIENCE RESEARCH COLLOQUIUM presents "The Power of Structured Data in the Message-Passing Interace" Prof. Jesper Larsson Traeff (Research Group Parallel Computing, Institute for Information Systems Vienna University of Technology, Austria) 29 October 2014 (Wednesday) 11 am - 12 noon Hatfield, College Lane Campus Seminar Room 1A159 Everyone is Welcome to Attend Refreshments will be available Abstract: The ability to communicate arbitrarily (statically) structured data via the derived datatype mechanism is a unique feature of MPI (the Message-Passing Interface). We believe that the power of derived datatypes, in particular in combination with the collective communication operations is still not fully explored, neither with respect to descriptive advantages nor their potential for improved performance. This talk will describe recent applications of MPI derived datatypes to improve complex algorithms for collective communication operations, and discuss open issues in the specification and implementation of efficient, derived datatype mechanisms. Short bio: Jesper Larsson Traeff is professor for Parallel Computing at the Vienna University of Technology (TU Wien) since August 2011. Before then he was professor for Scientific Computing at the University of Vienna. From 1998 until late 2009 he was working at the NEC Laboratories Europe in Sankt Augustin, Germany on efficient implementations of MPI for NEC vector supercomputers; this work led to a doctorate (Dr. Scient.) from the University of Copenhagen in 2009. From 1995 to 1998 he spent four years as PostDoc/Research Associate in the Algorithms Group of the Max-Planck Institute for Computer Science in Saarbruecken, and the Efficient Algorithms Group at the Technical University of Munich. He received an M.Sc. in computer science in 1989, and, after two interim years at the industrial research center ECRC in Munich, a Ph.D. in 1995, both from the University of Copenhagen.
