    This is presently Oak Ridge's fastest computer. I was computer operations supervisor in Oak Ridge's largest mainframe computing center for the last 25 of my 41 years with a prime contractor for the DOE. Our Center installed Oak Ridge's first supercomputer
    in 1985...the Cray XMP2 4

    This is the Jaguar...it is presently being upgraded:

    What it's like to play with the Jaguar supercomputer - Nov. 14, 2011

    I took a visitor's tour of ORNL in the early 80's.
    Don't remember a whole lot.

    A young employee from our old center set up a pass and visitor's information and spent four hours of his day touring me through the place. The technology has changed so much since I retired in 1993 that it's difficult to comprehend.

    hm. So you were working there when I had the tour? small world.
    There was a display with two mechanical arm things that you manipulated with your hands.
    Behind the glass was a bunch of toy wooden blocks. I started stacking them up when I noticed the tour guy quit talking. I looked over, and there was the guide and the tour group staring with their mouths open. I had about 12 of those blocks perfectly stacked LOL.
    Anyhow- just a fun memory.

    You're right about this being a small world.

    Actually you were at the National Laboratory. At that time there were three computing centers in Oak Ridge, (X-10) the national laboratory, (Y-12) the nuclear weapons facility and (K-25) the uranium processing facility and centrifuge development center. I was at K-25 for the entire 41 years of my career and in the computing center for 33 of those...computer operations supervisor for the final 25. I retired in 1993.

    The centrifuge development project financed Oak Ridge's first supercomputer, the CRAY XMP 24 and the capabilities it had in 1985 were trivial when compared to the super fast computers of today. The project took 14 months in planning and cost $11.8 million. That was a lot to pay for a processor in those days. It had two 250HP motor generator sets which did nothing but convert 60 cycle power to 120 cycle to provide a more stable DC voltage for the main processor. We had to install a special 13.8KV load center for the additional power requirement and about 40 tons of refrigeration for it's cooling demands.

    In 1991 we paid a salvage company $1,000 to load the thing on a truck and haul it away. Of course they were doing it to reclaim the precious metals from the circuit boards and cables.

    Click this address and it should show you a typical operations site of an installed XMP24. Of course one cannot see but a fraction of the total system, i.e. disk drives, tapes, plotters and other ancillaries such as power load center, cooling etc.

    Optical diode the wave of the future for computers?...
    :cool:
    More Powerful Supercomputers? New Device Could Bring Optical Information Processing
    Dec. 22, 2011 — Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
