GPUs? We don’t need no stinkin GPUs.
In May, Intel announced the Many Integrated Core (MIC) architecture, with a development kit codenamed Knights Ferry. NVIDIA has announced and started to deliver its next-generation architecture, Fermi. PGI’s Michael Wolfe presents an in-depth comparison of the two designs.
Chipmaker Intel is reviving the Larrabee technology for the HPC market, with plans to bring a manycore coprocessor to market in the next few years. During the ISC’10 opening keynote, Kirk Skaugen, vice president of Intel’s Architecture Group and general manager of the Data Center Group, announced the chipmaker is developing what they’re calling a “Many Integrated Core” (MIC) architecture, which will be the basis of a new line of processors aimed squarely at high performance technical computing applications.
Larrabee technology may find a home in high performance computing.
Intel’s GPU work stoppage gets scrutinized.
While Intel prides itself on maintaining a breakneck speed for processor development, the company’s Larrabee GPU effort just couldn’t keep pace with graphics technology development at NVIDIA and AMD. Intel revealed late last Friday that the company would not be delivering a Larrabee-based discrete graphics product next year, and has instead decided to use the work as the basis for a software development platform.
First version will be used as a “software development platform.”
The opening address of the Supercomputing Conference had a surreal quality to it in more ways than one. Between talking avatars, physics-simulated sound, and a Larrabee demo running HPC-type codes, it was hard to separate reality from fantasy.
One man’s attempt to to do regular-expression matching with the Larrabee instruction set.
Larrabee looks an awful lot like an x86 cluster node; anyone who has experience building HPC clusters has pretty good intuition about the design tradeoffs that make for a balanced and effective system. So it can be interesting to explore the Larrabee architecture, to look at the design choices Intel made, and what alternatives they might have considered or might consider in the future.
