Los Alamos Computer Science Symposium (LACSS) Los Alamos Computer Science Symposium (LACSS)

LANL is delighted to restart the Los Alamos Computer Science Symposium series after a 1 year interruption (following the passing of

  • Prof. Ken Kennedy who chaired the previous Symposia)

Motivation for the Symposium:

  • serve as a premier international event showcasing research and

development in high-performance computing

  • foster collaborations between national labs, academia and industry in the

HPC arena

  • promote computer science research that will advance HPC programs at

LANL and elsewhere

  • encourage a strong focus on HPC in the academic computer science

community

Symposium theme this year: hybrid and heterogeneous systems, including architecture and programming environments. LANL is delighted to restart the Los Alamos Computer Science Symposium series after a 1 year interruption (following the passing of

Roadrunner embodies many key architectural trends, each in moderation Roadrunner embodies many key architectural trends, each in moderation

Roadrunner has: multicore, short-vector SIMD, threads, heterogeneous instruction sets, local stores instead of caches, on-chip CPU/memory networks, remote accelerators and cluster computing. Any of these features can be used as needed, without requiring extremes in any one of them. Roadrunner’s scale and flexibility makes it an ideal base from which to explore the changing landscape of hybrid and heterogeneous architectures.

A LANL Update for LACSS A LANL Update for LACSS

To emphasize the importance of this area for LANL endeavors, we have established the Center for Advanced Architectures and Usable Supercomputing (CAAUS)

LACSS is organized under the auspices of CAAUS Some goals of CAAUS:

comprehensive focus on the design of new generations of high-productivity supercomputing systems grounded in applications of interest to LANL for the 21st century build a world-class computer science capability for HPC at Los Alamos attract staff at Los Alamos in computer science, and serve as a portal for staff integration into other technical activities at the laboratory build new programs to support LANL goals in HPC R&D
