    This WU 238
    is working from 53 hours and is still at 9.1%.
    At this rate the finish prediction is of about 550 hours. The deadline has just passed. What may I do? Abort it or continue computation?
    Thanks.

        Sziasztok!
        Szia Ádám!
        Ez a munkacsomag is kb. 890-900 óra hosszú, ami 37,5 nap azaz több mit 5 hét.
        Ennyi id? csak akkor, ha folyamatosan megy, de ez itthoni gépem, napi 4-5 órát ha megy...
        Valóban nem számít a határid??
        Szép nyarat!

          I believe that I have the same, or a very similar problem. Any chance of a re-post in English?

              Seems I\'ve stumpled upon such a wu as well: 36180

              20 hours and 40 minutes processed, 0.200 percent done and 1 day 17 hours remaining ;) Or rather, according to my calculations, 10,333 hours remaining ;)

              [added]That would be more than 430 days :D[/added]

                I have now decided to cancel all the WUs that are expected to run for more than 672 hours = 4 weeks, either if boinc 4.45 says so or if I figure it out myself for WUs running under boinc 5.2.13.

                Even if the result is accepted by Adam, he will never get 3 valid results without exceeding the maximum number of total results (= 8). So my effort would be useless to science. Maybe I\'m mistaken, but I have never read a straightforward answer from Adam to a post asking about WUs exceeding 1000 hours.

                If these WUs are really necessary to crunch, they should be reissued with an appropriate deadline. CPDN gives a deadline of 19 months for WUs that need 3000 hours\' crunching time.

                  I turned one of my crunchers back onto SZTAKI today to see how things were going, and immediately got this monster. Immediately it said 999 hours to go, deadline 30 days. Since when have we had 33 hours a day?? So I had a look at it, and it had 1000 lines to process. So I let it run for quite a while. In 9 hours it had processed 2 lines and was showing 0.2%. If those are representative it will take 4500 hours to crunch, which even at 100% dedication I make 187.5 days, or a little over half a year. I can imagine that after 4 months it will fail with maximum output exceeded or some such. So it is aborted and this rig is again on other work. There\'s 9 hours crunch time down the pan.

                  I don\'t like enormous WUs anyway, as I\'ve said in other posts. I certainly have no interest in WUs that want to run for an absolute minimum of 6 times deadline, the devastation to other projects is terrible.

                  Adam please, give some user selection to the accepted WU size, and a better accuracy to the deadlines. Most hosts crunch for multiple projects, I would guess you can\'t budget for more than 25% perhaps.

                  I\'ll watch the status here for a while but no more crunching from me unless this sorts itself out. All the more for Malaria etc.

                  I also note from the front page there are 9299 active hosts, but only 261 WUs returned in 48 hours. That seems to make an average of 35 days per WU per host if my arithmetic is ok. So on average no WU is making deadline at the moment.

                  With deepest regrets. Mike

                    I have to admit that I\'m thinking about dropping this wu. It\'s still at 0.200% and I was already in earliest-deadline-first mode when BOINC got around to this wu. I have one other wu that can\'t take much delay (a QMC wu) - it\'s not urgent with the others as they are all cpdn+ wu\'s.

                      Ok, the forementioned wu has crunched for 1 day and 5 and a half hours, progress has increased to 0.400% (yeeeeiiii :D) and haha to completion has increased to 2 days 1 hour and 47 minutes. So I might let it run to finish - although temporarily suspended to let the QMC wu finish before it\'s deadline

                            I\'ve seen two sorts of WU recently, one with a single very lengthy sub-unit of work, the other with 1000 sub-units. If anyone has other sizes I would be interested, you can tell the size by looking in the szdg project directory at the file with the name beginning \"in.txt\", each line is a separate sub-unit. For the single sub-unit file there seems to be one record, for the 1000 sub-unit file there are 1000. For the single case, the percentage completion sits at zero until it completes, for the 1000 unit file it goes up by 0.1% each time a sub-unit completes.

                            I think the percentage is a better estimate of how far through it is than the \"to completion\" time given the oddities of BOINC, though there is probably some variation in the individual sub-unit times.

                            This would suggest you have completed one sub-unit and are in the middle of the second, out of 1000. If you look at the files beginning \"ab\" I think one is the output from the sub-units processed so far, the other appears to list the individual sub-unit work items processed.

                            Anyone got any different sized WUs, or any correction or improvement on this theory?

                            I think 1000 sub-units is many times too much for a multiple work unit. 10 or 20 might be a better number, given the run-times we are all seeing for these.

                            That\'s my 2 forint\'s worth.

                              http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=

                              310, 37343, 37440, 37444, 38169, 39013, 39254, 39269, 39757

                              Munkacsomagokat meg kellett szakítanom, mivel 2 hétig áram nélkül lesznek a gépek, és így biztosan nem fejezik be ?ket.
                              Van-e remény arra, hogy az elvégzett sok-sok napi munkáért kerül-e jóváírásra valamennyi kredit?

                              37318 még fut, de hajlok afelé, hogy megszakítsam, most 32 óra alatt 2%-ot teljesített, összességében 22%-on áll 109 óra után.
                              A gép általában napi 4-5 órát megy, csak most maradt véletlenül bekapcsolva.

                              Nem lehetne egy kicsit rövidebb csomagokkal szórakozni? Úgy látom sokan már az elején megszakították a számolásokat.

                              További szép nyarat!

                                  My very long WU has finished with client error \"CPU time exceeded\", nice... :-\\
                                  96 hours of crunching for the recycle bin...

                                  It\'s WU ID 24331.

                                    I have a WU that is at 55 hours and .2% I am pulling the plug on it as it has only 10 days to crunch. If the idiots running this asslyum cannot give a reasonable deadline for completing a WU...then they do not deserve to have any volunteers. If they send me another one of these Super WUs and do not give a reasonable deadline...I will quit.

                                        Sziasztok! Szia Ádám!

                                        Ez a munkacsomag futott 187,457.92s-ig, de a végén számítási hibát adott, miután elérte a 100%-ot!!! Akkor most feleslegesen dolgozott a gépem?

                                        Úgy szurkoltam, hogy a nagyon rövid (talán 1 hét) határid? el?tt befejezze.
                                        Így csak tényleg annyit fog menni a gépem amennyit szükséges, az áramot nem adják ingyen.

                                        Most egy várhatóan 220 órás munkacsomagot kaptam, talán elég lesz rá a 4 hét, ha nem, akkor egy kis szünet következik...
                                        Talán nem kellenne 15-20 órásnál hosszabb idej? csomagokat készíteni, elegend? lenne 50-100, max. 500 sor.

                                        Nem kellene a népharagot kivívni magatok ellen.

                                        További jó mindennapokat!

                                            This WU has crunched for 39hours and got 1.9% complete. Also, having just looked, no-one has successfully returned it.

                                            Do I continue to crunch or limit my losses and bin it?

                                              Looks bad. Already three times a client error. If it was me, I abort it .... but ....
                                              And there are new short WUs available (+/- 5 hours on a P4 3.0)

                                                As Thierry said, it doesn\'t look promising. The \"Maximum CPU time exceeded\" error is particularly nasty: the two Linux systems errored out immediately, so wasted next to no time, but the Windows system spent 225+ hours. I doubt it\'ll get the 1200+ credits it\'s claiming ...

                                                    Your WU is already in error (reason: too many results). Even if you submit a seemingly valid result, it will go straight into the trash bin. Please limit your loss and cancel the WU immediately. The project has been unattended for 2 weeks, but Adam will come back probably this weekend. I suggest that you work for some other project for a few days, until he has sorted out the problems and we can start again with a clean database of shorter WUs that are able to be processed and give valid results. Sztaki is my favourite project, but I have unfortunately come to the conclusion that I had better suspend my participation until it will be possible to have valid results.
