      • data while consuming a fraction of the power and floor space required by today's fastest systems.
      • to analyze scientific and biological problems
      • (protein folding).

      • March 2005 – IBM started renting the machine for about $10,000 per week to use one-eighth of a Blue Gene/L rack.
    • 11.
      • In computer science, the kernel is the fundamental part of an operating system.
      • It is a piece of software responsible for providing secure access to the machine's hardware to various computer programs.
      • Since there are many programs, and access to the hardware is limited, the kernel is also responsible for deciding when and how long a program should be able to make use of a piece of hardware, which is called multiplexing.
      • Accessing the hardware directly can be very complex, so kernels usually implement some hardware abstractions to hide complexity and provide a clean and uniform interface to the underlying hardware, which helps application programmers.
