Brian Scarbeau Insights from a seasoned Computer Science Trainer

A petaflop is a measure of a computer's processing speed and can be expressed as a thousand trillion floating point operations per second.

FLOPS are floating-point operations per second. Floating-point is considered to be a method of encoding real numbers within the limits of finite precision available on computers.

Using floating-point encoding, extremely long numbers can be handled relatively easily. A floating-point number is expressed as a basic number, an exponent, and a number base which is usually ten but may also be 2.

Now that you know this... would you believe IBM is developing a supercomputer which is super fast!

Seven months after IBM delivered the world's fastest supercomputer, it has announced an even speedier one with the computing power of 2 million laptops.

IBM said on Tuesday it is developing the technology for its new Sequoia computer, with delivery scheduled in 2011 to the Department of Energy for use at Lawrence Livermore National Laboratory.

Sequoia will chug along at 20 petaflops per second and is one order of magnitude quicker than its predecessor. The earlier machine, delivered in June to the Energy Department, broke the 1 petaflop barrier.

I need to add this word to my dictionary.
