Einstein@Home passes 1 Petaflop of computing power!

Submitted on 6 Jan 2013 20:52:14 UTC

Congratulations and thank you to all Einstein@Home volunteers: sometime shortly after January 1st 2013, Einstein@Home passed the 1 Petaflop computing-power barrier. To put this in context, according to the current (November 2012) Top-500 computing list, there are only 23 computers on our planet that deliver this much computing power.

(One Petaflop is 1,000,000,000,000,000 floating point operations per second.)

Congratulations and thank you again, and keep on crunching!

Bruce Allen
Director, Einstein@Home

    This

    With unlimited computing power, we could search any parameter
    space, no matter how large. In practice, the finite computing
    power of Einstein@Home dictates that we only search
    some part of the parameter space.

    is from page 5 of the paper.
    How much computing power is necessary to compute 'any parameter space'?

      it says it in the quote... Unlimited

          Now we hit the Peta Flops

            Now we hit the Peta Flops again. With regular estimation of gamma ray cedits/Tflops.

            Good to see

              That may have been partly influenced by a brief outage at SETI on Tuesday night, while Campus upgraded network infrastructure.

              They have another planned outage coming up, for three days starting Monday 1st. April, while their servers are moved to a new facility. That will put extra pressure on the servers here until SETI is back online.

                  Hiya - you're probably better off posting this in the Problems and bug reports forum. The host log for your computer it says "[send] work_req_seconds: 0.00 secs" but I don't know what that means - someone probably will over in the 'problems' forum. Perhaps check to see if the project needs to be 'resumed'? (if the button on the project list says "Resume", click this once).

                    It means that the Client doesn't request any work when it contacts the server - for whatever reason.
