Cell Processor
  • Co-developed by Sony, Toshiba and IBM
  • 9 Processor Cores in a chip
    • 1 Power Processor Element (PPE) – 64-bit PowerPC two-way multithreaded processor @3.2GHz
    • 8 Synergistic Processing Elements (SPE) – 128-bit SIMD RISC processors
    • Only 7 out of the 8 SPE are being used
  • An enhanced version, PowerXCell 8i, is used to power the world fastest super computer
  • Most powerful processor among PS3,Xbox 360 and Wii(Warning: personal bias)

  • To study the process of protein folding using computers all around the world.
    • Works on PCs and PS3s around the world
    • To better understand diseases such as BSE (Mad Cow), Alzheimer's, Huntington's
  • Need massive computing power:
    • about a day to simulate a nanosecond (1/1,000,000,000 of a second) of protein folding
    • 30 CPU years for 1 protein fold
  • In Sept, 2007, awarded Guinness World Records as the “most powerful distributed computing network.”
    • > 1 petaFLOPS
