    Well someone had to do it.

    I had a flick through the stats and noticed a bunch of computers that are truly awe inspiringly fast. Like Core 2 Quads that must be running at 6+ GHz to achieve the kind of benchmarks they're getting.

    Except, they are running 5.5.0 clients. You know, the unofficial one that was used to vastly, vastly overclaim credit. It was outright banned on some projects. Problem is, with a quorum of just one, people will get credit based on what they claim.

    And that's really unfair.

    For some comparison purposes, this host is overclocked and running at 3GHz. This host might well be overclocked, but it's benchmarks are 241% higher, which by my reckoning (bearing in mind the BOINC CPU benchmark is about single threaded performance) means it must be running at 7.23 GHz. Er, no, don't think so.

    So either ban it, and half the credit for anyone using it, or just give us the ok to claim however much credit we want.

    Can we have a statement from an admin please?

      Hi Biggles,

      we are working on a new credit system, which grants fixed credits per wu ...

      thx for crunching and best regards,

        Will this be implemented on the PS3 app as well?

          Hi Maxwell,

          this isn't a app-based change ...
          After that every host will get 200 credits per WU.

            This will be good. I was going to tell you I was detaching because the credits were just too low for me to continue supporting this project. I am dropping some other projects as well for the same reason. While I am not a credit hound, I do like getting a good return on for my time. The one thing that has kept me here is the smoothness of this project. I rarely have problems getting work or reporting work. That's a big plus in my book.

              That could be a problem with the length of a WU. Try to calculate around 40cr/h with a standard cpu, so you can define a value in shorter or longer runs in WU template but this isnt a good solution I think.

                Hi rebirther,

                what is "a standard cpu"? ;-)
                I talked to a lot of BOINC-users and they said, that 50 credits/hour would be ok ...

                a primaboinca WU needs at a single core Intel 2,0 GHz < 4 hours of computation, so that the credits granted "c" should be: 150 > c < 200 ...

                the main reasons for granting fixed credits are:
                - "real" PS3/CBE apps (like primaboinca) mostly crunch using the SPEs
                - hacking/manipulation

                Best regards,
                Fabio

                  A standard cpu I mean is what you have it. I really like fixed credits so find the best solution to set it up ;)

                    Your plan sounds fine. Run with it. Don't get sidetracked by "special interests".

                      I totally agree. This is great news. Thanks!

                          There are some more hosts with running 5.5.0. The best solution at first is to allow only hosts greater than 6.x. Check also the first top 20 in stats, you will surprised to find some of them there. To delete an account could get negative effects on db. Better to set it back to zero. As long as fixed credits are not set yet try out the first point.

                            BOINC version can be spoofed almost as easily as benchmarks.

                            Fixed credits will solve it all.
