sc09-larrabee-sgemmAt the recent Supercomputing2009 Conference in Portland, OR, Intel’s Justin Rattner talked about the Rise of the 3D Internet as a tool for collaboration and presentation of HPC resources in a friendly way to users.  Disguised in the middle of his talk was a few slides about the upcoming Larrabee chipset with a live on-stage demo. He showed the chipset and ran a few demo’s with some help from Pradeep Dubey, and from my notes:

  • SGEMM – Using only half the cores of larrabee, 380GFlops.  With all cores enabled:700Gflops
  • SPMVM Sparse Matrices – QCD – FEM_CANT – About 8GFlops

In addition, he discusses the “MYO” (Mine-Yours-Ours) memory architecture where there is not the usual separation between CPU Memory & GPU Memory.  Another interesting tidbit was that not once during the entire hour-plus presentation did he refer to Larrabee as a Graphics Chip or GPU, but rather as a Compute Accelerator.  An interesting change in terminology for a company that previously wanted to wipe out NVidia in the graphics space.

The entire talk is now available on Youtube, and I’ve embedded it after the break.
