Accelerator-based Computing and Manycore
Manycore and Accelerator-based Computing for Physics and Astronomy Applications
SLAC National Accelerator Laboratory/ Lawrence Berkeley National Laboratory, Berkeley CA, USA
November 30 – December 2, 2009
SLAC, NERSC, LBNL and UC Berkeley hosted an international workshop on the role of emerging many-core architectures in science and technology. The focus of the workshop is to usher experts and enthusiasts from disparate backgrounds in academia and industry to introduce, explore and discuss the scope and challenges of harnessing the full potential of these novel architectures for high performance computing specially in Physics and Astronomy applications. The developed solutions will have broader impact across science and technology disciplines such as healthcare, energy, aerospace etc. The emerging new techniques open a route for future generations of hardware and software using silicon and electrical power much more efficiently, a necessity on the path to Exaflop/s.
Emerging many-core architectures – Graphics Processing Units (GPUs), Cell, many-core CPUs – offer unprecedented potential for energy efficient high performance computing (HPC) in science and technology. Limited early adoption of such architectures by a broad range of compute and data intensive applications has distinctly demonstrated unmatched gains in acceleration and power consumptions. This workshop strives to set the stage for academic and industry leaders to enable partnerships for growth of research and innovation in the broader community. Early adopting core science teams from Asia, Europe and America have an opportunity to get together to coordinate next steps and establish a regular transcontinental forum in the next years.
The very first confluence for such a group aims to achieve:
· A large footprint of international collaborations
· Educational and training prospects for future researchers, educators and students
· Leadership role for participating institutions and facilities in the cutting-edge technologies
· And Academia-industry partnerships with entrepreneurial opportunities
