Response to: an important piece is missing.....

There is now way that a external software can always find a intermittent memory fault.
You can do some things that is acceptable on a workstation that do graphics but if you do science or manufacturing work were every result is important you basically have to recalculate everything twice on different nodes, this will lower the peak performance with 50% but is the only way to know that the result is the right one.


This is a fantastic system but for organization were the result has to be correct they better look at a system with ECC.

    Wow, anonymous, it's too bad all of those supercomputing guys didn't ask you! You could have set them straight before they wasted all that time and money. I guess you'd better let the folks at top500.com know, quick - they must have missed it before now.

    OR, just MAYBE, you have no idea what you're talking about. It's a relatively simple exercise in software development to identify spurious results via multipl iterations. ECC memory won't protect you from processor faults and other glitches anyway, so the software has to be robust enough to allow for bad results even with expensive memory.

    But thanks for playing.

      Thank you to
      You even prove me right what do this mean:
      It's a relatively simple exercise in software development to identify spurious results via multipl iterations.

      This mean that you have to do everything multile times to prove your result.

      But it look nice to have the peek performance to put you on the TOP500 list.

        both Apple and Dr. Varadarajan seem to be clear about what they are doing and it certainly seems like a success story for both.

        SO ALL YOU GUYS CAN SHUT THE HELL UP AND GET BACK TO WORK!!

                Think of managing other $5.2M software engineering
                projects ...

                mmm peanuts
                mmm single precision Altivec objects

                What brand of peanuts could sell good?
