TITLE: "MPI on a million processors - and less"

TIME: Donnerstag 15.10.2009, 14:00 st.

LOCATION: Nordbergstraße 15/C316, 1090 Wien

SPEAKER: Jesper Larsson Träff
NEC Laboratories Europe, St. Augustin Germany

ABSTRACT:
This talk will explore some of the obstacles (and promises) of scaling
MPI, the Message-Passing Interface, to massively parallel systems with
millions of processors.  The exploration will consider both the MPI
interface itself, discussing improvements and changes for better
supporting massive scaling that are being addressed in the currently
active MPI Forum, as well as new issues related to the efficient
implementation of MPI on such systems. Some of the issues are also
relevant for implementing MPI on emerging, memory- and bandwidth
constrained multi-core systems.

The talk is based on joint work with Pavan Balaji, Darius Buntinas,
David Goodell, William Gropp, Sameer Kumar, Ewing Lusk, and Rajeev Thakur.

SPEAKER BIOGRAPHY:
Dr. Jesper Larsson Träff, who is currently chief researcher at the
NEC Laboratories Europe in St. Augustin (Germany), has been active
in parallel processing research and development since the early 90ties.
In the past decade he was with NEC where he has mostly been involved
in research and implementation of message-passing interfaces.
He collaborates actively with research groups in Europe and the
United States (Argonne National Laboratories), and has been involved
in numerous European Commission funded projects (Compulog, ALCOM,
SEPTOOLS, APART). He is actively representing NEC in the MPI Forum
which is currently active in designing extensions to MPI (MPI-3).
He holds a PhD and a Doctoral Degree (Habilitation-like) from the
University of Copenhagen, from 1995 and 2009, respectively. He is
a frequent member of program committees for relevant conferences
and workshops in parallel and high-performance computing, e.g.
Supercomputing (2008, 2009), IPDPS (2008, 2009), EuroPVM/MPI
(from 2002), HiPS (2007, 2008, 2009), and many others. He recently
co-edited a Special Issue of Scientific Programming on software
development for multi-core systems. He (co)organized the EuroPVM/MPI
2006 conference in Bonn, Germany, with around 130 participants.
He has (co)initiated the Euro-Par Workshop on Highly Parallel Processing
on a Chip (HPPC ), now in its third incarnation.
