    Hi,

    I have a WU submitted the 13th of this month that is still pending:

    http://szdg.lpds.sztaki.hu/szdg/result.php?resultid=1506169

    I have since submitted other WU that have been validated...

    Something wrong with it ?

    Thanks

      Nothing is wrong.
      On this project, the minimum quorum = 3 (initial replication = 3).
      The third result (1506168) has been sent and is \'in Progress\'.
      The 2 others result will stay \'pending\' until the third result is come back \'at home\'.

        Thanks.

          All three results for the quorum have been in with outcome=\"success\" since 24 July for this WU, but it is still pending. Any reason for it being \'stuck\'?

            The word \"success\" means that a cruncher has crunched the WU and sent back a result file without problem. But the validator is still not happy with the outcome and wants a further result. The last crucher sent back the result on 24 July 2007 20:51:18 and the server created immediately a new WU on 24 July 2007 20:52:31. This hasn\'t yet been sent out because there is a long queue on the server. Look for instance at this WU that was sent out a few minutes ago after having waited for 76 days.

              In other words the turn around time for a WU to be validated is going to be longer than other BOINC project?

                In rare occasions, the WUs are short, the 3 crunchers start immediately and the validator agrees. Then this project is like any project with a quorum higher than 1.

                Usually, however, the whole process is much longer, due to 3 reasons:


                • The processing length of a WU is unpredictable at its start, and this means that Boinc is not very efficient in calculating the number of WUs that a cruncher should get, as Boinc considers the length of previously crunched WUs. In order to compensate for this, Sztaki has a 28 day limit. Sometimes, a WU needs only a few minutes to be processed, but if 1 cruncher doesn\'t send in the results, the 2 fellow crunchers must wait for 28 days until the server understands this.
                • This project doesn\'t require fast results in order to create new WUs, unlike projects like LHC or the (dying) Chess960 project which need fast results. A project gets the most of its limited resources in the long term if the number of initially created WUs is kept to the minimum, i.e. the quorum number.
                • This project has created many WUs at the same time (too many IMHO) and these fill the waiting queue on the server.


                Conclusion: in the long run, this project uses the resources in the most efficient way, but it is not attractive to crunchers who want validated results and/or credits immediately.
