[LA-SiGMA-TESC] Technologies for Extreme Scale Computing seminar on Thursday (9/4)

[Wei P Feinstein]

Hi all,

We will continue our weekly seminar this Thursday (9/4) at 12:00pm-1:00pm in 1034 Digital Media Center.

Dr. Hartmut Kaiser, a senior research scientist at CCT and a member of the faculty at the CS department, will give a presentation titled " Asynchronous Computing in C++".

Abstract:
With the adoption of the new C++11 Standard the community sees a
revival of interest in the language. This interest is also driven by the
demands that new computer architectures and technologies are exerting on
application developers and domain scientists. Especially the need for highly
runtime adaptive algorithms and applications puts a great strain on our
ability to efficiently write code which performs well and which scales
satisfactory, as multi-core and multi-threading is the new modality of
computation. We argue that new programming models have to be developed if we
are to gain continued scalability of computations as we increase the size of
our systems. These are programming models which work equally well for
inter-node as well for intra-node use. With the degree of complexity and
size increasing in new hardware architectures, applications are more and
more hindered by the main bottlenecks in computation, namely starvation,
latency, overheads, and waiting for contention resolution. We present HPX,
which is a general purpose parallel C++ runtime system implementing a new
model of computation - ParalleX, that attempts to address those challenges.
We show results from using HPX for leveraging and managing asynchrony,
overlapping different phases of computation and communication, suggesting
ways to seamlessly expose it to programmers in an easy to use way.

Bio:
Hartmut is a member of the faculty at the CS department at Louisiana
State University (LSU) and a senior research scientist at LSU's Center for
Computation and Technology (CCT). He received his doctorate from the
Technical University of Chemnitz (Germany) in 1988. He is probably best
known through his involvement in open source software projects, mainly as
the author of several C++ libraries he has contributed to Boost, which are
in use by thousands of developers worldwide. His current research is focused
on leading the STE||AR group at CCT working on the practical design and
implementation of future execution models and programming methods. His
research interests are focused on the complex interaction of compiler
technologies, runtime systems, active libraries, and modern system's
architectures. His goal is to enable the creation of a new generation of
scientific applications in powerful, though complex environments, such as
high performance computing, distributed and grid computing, spatial
information systems, and compiler technologies.
