      One idea :

      %Efficiency for one computer = (Granted Credit/Claimed Credit)*100
      %Average Efficiency of computation=Sun of Efficiency for one Computer/Number of computer

      Repr?Šsentent on a diagram this Average Efficiency regarding to the time
      You could add analyse of the distribution on the same graph

      (Sorry for my bad english)

        Good idea.

        An additional column in the list of computers showing the recent percentage of error results would maybe help the PC owners look for those boxes that do not run so well.

        Above a certain error portion, an eye-catching alert color would add even more value to this feature.


        @Paulatreides : You should check the setting of \"Leave applications in memory while preempted?\" in your general preferences. It needs to be set to Yes here as SZTAKI results are currently not restartable, that\'s most likely the reason why your results often fail to validate.

        Look at \"stderr out\" of the invalid results, they all mention a \"Restarting from checkpoint\" which (nearly) always makes the results fail.

          Thank you very much for all that explanations :-)

              Yes, that\'s what I mean.

              Try leaving the application in memory while a different project is working and this problem will be reduced to those cases where you shutdown BOINC.

              It will not happen anymore when your BOINC is busy with a different project.


              It is a known problem btw. - and we all hope that Adam finds a way to fix it soon.

              Post to thread
