Sometimes the language surprises even those of who try to keep up with technological innovation.

“An American military supercomputer, assembled from components originally designed for video game machines, has reached a long-sought-after computing milestone by processing more than 1.026 quadrillion calculations per second.

The high-performance computing goal, known as a petaflop — one thousand trillion calculations per second — has long been viewed as a crucial milestone by military, technical and scientific organizations in the United States.

“The next thousandfold goal is the exaflop, which is a quintillion calculations per second, followed by the zettaflop, the yottaflop and the xeraflop…”

  1. Although the term “xeraflop” appeared in a reputable online news article the prefix “xera-” is in fact a hoax.

    The term originated from a wikipedia article. The source was not checked and was used and then proliferated across the web.

    Currently the official SI prefixes only go up to 10^24 (yotta-). However there are many bogus prefixes that can be found online. The xera- is simply one of the lastest and perhaps most successful examples.

    I have a website on large numbers, and I go over the SI prefixes. I even have an entire article devoted to hoaxes and proposed extensions to the standard system. You can learn more about the xera- hoax, and many other prefixes at …

    This page includes several links leading to various articles on the SI prefixes. If anyone is interested check it out.

  2. I am an atomic scientist working on solutions for the three fully melted down Fukushima reactors.
    You are right on. Yottaflops is scientifically recognized, the rest are bullblank.
    You can’t get any better than scientist backing.
    Carry on. Peace.

    You like numbers, so off of the top of my head only as a scientist, speed of light: 186,282 miles per second. Speed of sound: 761.454 miles per hour at 59 degrees at sea level with a barometric pressure of 29.75.
    Take it easy, and have a good one.
