    People are facing \"some\" problems because of the lenght of wus sent since 23 feb. (machines overcommitted, deadline, wus aborted, mode EDF, no credits ...)

    The project administrator is working on it right now but he needs some days in order to correct problems.

    So thanks for your understanding and your patience.

      thanks for update. Its good to get confimation someone is working problem and to stop the useless posts.


      In the future, it would be nice if administrator posted a \"news\" update defining the concern, eta for resolution, and suggested actions by participants (suspend, reset, etc).

      In the meantime, I currently have reset and suspended my SZTAKI projects until the ok is given. I have done this because to completely took over cpu time from all other projects.

      Awaiting future orders....

          The longer WUs have all been sent out, so hopefully from now on the problem will slowly fade away. If anyone has a longer WU under processing, you are free to cancel them...

                New deadline :
                For wus sent since 1 march, the deadline has been extended to 5 days.

                  I have two PCs are setup with SZTAKI. They have successfully their workunits, which were all credited in time (long before the deadline), but since a few days, they don\'t get any new workunit, even after trying to force the update manually from the BOINC interface.

                  This does not occur either after PC reboots.

                  (For now, my PCs are just crunching for other projects due to lack of work units in SZTAKI.)

                  My PCs have fast enough processors (a desktop with an AMD Athlon XP+, and a notebook with AMD Turion 64ML) running both at more than 1.6GHz, much enough RAM (1GB each), plenty of free disk space (and they are almost never shutdown, except for short restarts to finalize the installation of security updates, at most once a day...)

                  When I look at the SZTAKI server status, I see that there are plenty of workunits ready to process, and I see other people getting credits for new workunits they started during thesedays, so why are\'nt they served to my PCs?

                  Subsidiary question: what is \"EDF\" mode in BOINC? I\'ve not been able to determine what this acronym means in the BOINC setupinterface or in the project account settings. (For me in France, \"EDF\" is just the name of the most important french electricity company, and the largest in Europe)
                  ---
                  Correction: one of my PC just got 1 work unit. (But the deadline is 4 days, not 5 as you indicate in this thread. It will complete it fast...).
                  The second PC has finished its workunit since several days, and its credits are still pending, with no additional workunit to process.

                    It stands for \"Earliest Deadline First\", and means that BOINC is overriding the host\'s resource-share preference to prevent missing deadlines. Here\'s the BOINC Wiki article on the topic; let me know if you need help translating any of it into French.

                      If you look at the workunit itself, you will see that it was created BEFORE March 1st. Those workunits still have a 4 day deadline. Only workunits created after February 28th have the extended 5 day deadline.

                        Why is the deadline so short anyway? Will a meteor hit the earth when the results don\'t return within 5 days or will a green fire dragon visit the cruncher?

                        But seriously, this project is not so much under time pressure (correct me if I\'m wrong) so it couldn\'t \"affort\" a 10 days deadline.


                        Towards the end of a project phase, I would see a reason for short deadlines so we can get to the next stage quicker.


                        It is probably not so much a problem for people crunching SZTAKI as their main project but the majority of crunchers has SETI, CPDN or Einstein. Of those, more would be able to use SZTAKI as their backup project if the deadlines would be extended.

                        Another advantage : With a 10 days deadline it wouldn\'t cause so much trouble if a few long running ones slipped through now and then ;-)

                          The main reason I would say we need a 10 day deadline is that you can set the maximum cache size to 10 days, so if you did have it set on your BOINC client, chances are it would also run on panic mode if there was any SZTAKI WU\'s in there

                            Can anyone reply to my two questions in this previous post?
                            (1) Why my PC\'s doin\'t have any workunit to compute, even when I attempt to update manually, nothing is downloaded (if I try to update manually, it just updates the statistics, but it indicates:

                            05/03/2006 10:38:18|SZTAKI Desktop Grid|Sending scheduler request to http://szdg.lpds.sztaki.hu/szdg/cgi-bin/scheduler

                            05/03/2006 10:38:18|SZTAKI Desktop Grid|Requesting 3600 seconds of new work
                            05/03/2006 10:38:23|SZTAKI Desktop Grid|Scheduler request to http://szdg.lpds.sztaki.hu/szdg/cgi-bin/scheduler succeeded
                            05/03/2006 10:38:23|SZTAKI Desktop Grid|No work from project

                            (but there are plenty of work units ready to compute in the project outgoing queue when I look at the server\'s website)

                            (2) How can \"EDF\" mode affect me, given that all my deadlines are more than 1 day, even for the shortest projects like \"Leiden Classical\" which has short work units and short deadlines, and that my PCs are not overcomitted (no message indicates that in BOINC), and continues to get workunits from all projects.

                            This is not \"useless\" post, like somebody said here...
                            Thanks.

                              No. That downloaded work unit really had a 4 days deadline, and it WAS created AFTER February 28, and downloaded AFTER February 28... It was computed and transmitted in less than 1 day, and since then, I still don\'t get any new work unit to compute. Again...

                              Look at my results...
                              http://szdg.lpds.sztaki.hu/szdg/results.php?userid=3072

                              On March 3 I had 3 work units that were computed in a matter of a few minutes. Then I had a larger work unit that was finished the same day.
                              Ans since 2 days, there\'s nothing to download.

                              How can some users listed on your statistics page get so many \"recent\" credits (more than 700 a day, which means about 20 to 30 work units) if there are not enough work units for everyone? Are there \"priviledged\" users that can get those work units and many others left without anything to crunch, despite there ARE work units available on the server?

                              It is interesting to look at the graph of total grid performance. It is constantly decreasing (in terms of Teraflops). There is certainly a problem in the database, in the way it handles users statistics to see if it should send work units to them (many users seem to be excluded, and I don\'t see the rationale for this).

                              Do you have TOO MANY users for the work units you really have to perform? If so, why do you accept new subscriptions? Couldn\'t you use this available processing power to incrase the accuracy of results, by letting 4 distinct computers compute the same work unit, so that you\'ll be sure to get 3 results within the deadline, and be able to accurately check the results with 2 identical results, instead of just looking for one finished result (which may be wrong)?

                              The longest work unit I got was computed by 3 computers. But submitted to a 4th one, and my claimed credits are still pending. The 4th computer that got that same work unit also got many work units at the same time:
                              http://szdg.lpds.sztaki.hu/szdg/results.php?hostid=13508
                              (and has not completed any since then...)

                              So it seems that this foreign PC is blocking my computer to get new work units, given that I have a work unit that was completed and transmitted before the dead line of February 27 (and finished as well by two other PCs), but now there\'s a PC crunching it AFTER since March 4, and that downloaded a large set of work units exactly at the asme time, but with 2 distinct dead lines of 4 or 5 days, ending on March 8 or 9...

                                don\'t know what server Page you are looking at but there has only been 1 WU in the ready to send list all weekend so that is why you have no work from here

                                    don\'t know what server Page you are looking at but there has only been 1 WU in the ready to send list all weekend so that is why you have no work from here

                                    There has been updateson the server. I just check it again and there are more than 3000 workunits available. And still, my PC can\'t get any, and BOINC just displays \"No work from project\".
                                    I have also tried to detach from the project and to reattach to the account, without more success at first: the server did not evenreply to my attach request (there was an error displayed in BOINC after Ientered my account and password, but the error message in the redbox was empty, not specified).

                                    Well I have just retried to reattach to the project, and I finally got 2 workunits.

                                    I looked at the database, and did not see the crunching workunits listed.
                                    So I have logged out from this website and relogged in.

                                    I have seen that a *new computer account* (computer ID) was created.

                                    Apparently, the previous computer account was not accessible from the database.
                                    So finally I have just merged the two entries for computers (the old one with past workunits that were completed since February 27 and blocked since then, and the new computer ID that was just created).

                                    Apparently, the database has broken my old computer ID on February 27, and was no more able to give it more workunits because the computer ID no longer matched (I have looked in my local logs, and my computers have in fact NOT changed its computer ID. The computer ID was garbled in your database, or inaccessible,although my credits were still there and still attributed to my user ID).
