Fine-grained parallelism on modern computing architectures

Main informationBy: Olivier Aumage (INRIA, Bordeaux, France)

Date: Monday, 10th of November 2008, 14h00

Location: FCT/UNL, Seminar Room (Ed. II)
AbstractParallel computing architectures have undergone several deep transformations over the last ten years or so, with the spreading of multi-processors followed by multi-cores processors and now followed by the many-cores processors, the introduction of non-uniformity in processor-memory accesses, and more recently the introduction of non-uniformity among the processors and cores themselves as with the IBM Cell or the general purpose GPUs. This talk will present some background, as well as current and future works of the INRIA Runtime team on providing efficient, portable runtime systems and software environments to help programming such architectures and keep-up with the evolution.
Short-bioOlivier Aumage got his PhD at LIP, École normale supérieure de Lyon, France in 2002, on the subject of high performance communication support. He then made a PostDoc at Vrije Universiteit, Amsterdam, NL, in the team of Andrew Tanenbaum and Henri Bal during the 2002-2003 academic year, where he designed the communication subsystem of the Ibis programming environment for Grid computing. Since 2003, he holds a full-time researcher position at INRIA in Bordeaux. He worked several years in the field of high performance networking. He designed the Madeleine communication library and initiated the work on the NewMadeleine library. He is now in charge of the development of the multithreading software in the Runtime team. He is also the coordinator of an upcoming 3-years french collaboration project on the theme of programming hetereogeneous multicores in the field of scientific computing.
