  • Recent offerings from NVIDA show that small companies or even individuals can now afford and own Super Computers.Just what is a Super Computer?

  • A supercomputer is a computer that is at the frontline of current processing capacity, particularly speed of calculation. wikipediaThe term supercomputer itself is rather fluid, and today's supercomputer tends to become tomorrow's ordinary computer.

  • In computing, FLOPS (or flops or flop/s) is an acronym meaning FLoating point Operations Per SecondTodays two fastest Super Computers operate at > 1 petaflop/s (represents one quadrillion floating point operations per second. )

  • Most applications use double precision math for the following reasons:To minimize the accumulation of round-off error, For ill-conditioned problems that require higher precisionThe 8 bit exponent defined by the IEEE floating point standard for 32-bit arithmetic will not accommodate the calculation, orThere are critical sections in the code which require higher precision.

  • Some of the latest GPUs and CPUs have LARGE differences in flops for single vs double precisionResearchers are recognizing this trend and re-examining their algorithms to take advantage of single precision whenever possible
