    The project is running again, total credits are fixed, but validation is currently disabled.

      We’re slowly working our way towards a solution to the whole credit/scheduling issue we’ve experienced over the past week. Today we took the project offline in order to restore host, user and team credits from our backups (the situation last Friday). We then went through all the valid results that we received in this period, and worked out the correct amount of credit to be granted. Based on that we then updated the credit records to today’s total.

      A few comments:

      -We did not recalculate recent average credit scores; this will happen automatically, but take some time to adjust.
      -Validation is currently disabled. We plan to re-enable this on Monday, in the mean time your results will be left unvalidated with credit pending.

      Sorry again for the rather chaotic week. Those of you that have been with us for some time know that this is quite exceptional.

      Thanks for bearing with us.
      Nick

        A massive thank you to all of the project team for the work they've done to resolve this week's problems. Leaving the validator disabled until Monday when it can be closely monitored is a good call.

            Some of us received credits that were substantially lower than what we should have received. Have those been corrected as well?

              The only credits that count are the number of scientific papers presented and the number of lives saved.

                Thank you for the hard work and the updates on the stats. Robert Johnson is correct, however as I noted recently, we participants like to see that our efforts are contributing to malaria research and saving lives. I contribute to the Computing for Fresh water project on the World Community Grid in the hope of saving lives.

                  The credit issue may or may not be fixed, I am still down somewhat, but not hugely, and it is of little consequence. The run time estimates can still be way out, that DOES have impact for me. On my server I have a unit that has, allegedly, 110 hours still to run, deadline in 4 days - it is in high priority now.

                    According to BOINstats your total credit has increased by 803 since the problem started (from 231,880 to 232,683).

                    The run time estimates can still be way out, that DOES have impact for me. On my server I have a unit that has, allegedly, 110 hours still to run, deadline in 4 days - it is in high priority now.

                    It sounds like you need to reduce your DCF as described here.

                      I said it was of little consequence, but as you seem to doubt what I said, I will say on 21st Nov I got 37532.1, this appeared due to a humungous credit on a single wu, this has been altered now so I cannot refer to it. On 24th I got -32286.4 and then on 26th -5947.9. The two negatives together are -38234.3 which MORE than compensates for the 37532.1.

                      It is hardly suprising that my overall stats have increased in the meantime because the other wu's I have completed in the meantime will have done that. You would deny this?

                          Are we close to having a validater?

                            I am awaiting validation of over 50 tasks @ 04h00 UT, Tuesday 30 Nov. I have stopped processing malaria tasks and am concentrating on Computing for Clean Water and Clean Energy 2......I will check later on Tuesday.

                              I've just enabled the validator. Current credits granted look promising (no one should get miniscule amounts of credit now).

                                I suppose it will take some time to validate the backlog of workunits..
                                On the status page we see 131,316 wu waiting for validation, and it is not going down quick.

                                Nevermind as long as credits end up in my pockets..

                                Ive got something like 600 workunits in that queue :)

                                  Hopefully all will be going well in due time: I reinitiated processing malaria about 24 hours ago and now have 400 plus units pending and ONE (only) validated.

                                  Team Boinc Synergy has designated malaria as Project of the Month (Dec.) so we should add a few work-unit completions to the effort in short order.

                                    The Validator has been restarted this morning. We are currently monitoring the credit granting and until now no gigantic credits or too little credits have been observed.

                                      This morning the validator had a backlog of 131,316 wu.
                                      Now, 7h30 later, backlog is 131,830 wu.

                                      I hope the validator is going to eat vitamins now :)

                                        It's got the backlog down to 122,000 now, so making some progress. If performance doesn't improve now, we may have to make further measures.

                                              Why did I have 21,500 on 24 November, 20,000 on 26 November and am now at 20,764???

                                              Although the most obvious over crediting was on tasks which were granted >40k, a much greater number of tasks were being granted >100 credits.

                                              The correction on 24th November sorted out the first group, with the second group (plus tasks which had been under credited) being corrected in the full recalculation on 26th November.

                                              The over crediting started on 20th November, the day after the project was upgraded to use the new BOINC credit system. Your account history on BOINCstats shows that your credits increased by 1,760 (from 19,739 to 21,499) before the second correction, when your total decreased by 1,499. That means you had a net increase of 261 for that week.

                                              Your increase since then is due to the server working off the backlog of tasks which hadn't been validated while the project team were investigating the problem. Some workunits which included at least one task run with openMalariaA v6.51 have received >100 credits since validation was re-enabled. I've no idea if this over crediting will be allowed to stand (the distribution between users is probably much more even than it was first time round).
