    I have a number of results where I have been given zero credit. There are 4 results returned, one with zero credit and the other 3 have claimed credit. Can admin look into this please.

        Hope Adam sees this.

        Same here, getting zero credits on some WU\'s.
        I was the 4th to return a result on the last one where I got 0 credit.
        The others got 1.71 credits.
        Why is this happening?

        I will suspend SZTAKI for a while until we get some informaton about this problem.

        thanks,
        Richard

            WUs getting shorter and shorter. Currently the server communication often needs more CPU time than the result.


            It\'s nice that the program is so fast but maybe it would be possible to bundle WUs somehow or even better : Send a rule that enables a host to create work, send a range of the variable parameters and a step width. Stuff these three things into one workunit and expect a package containing a matrix of 1000 of the current micro-results back a few hours later.

              ...



              I had two that were done in 1 (count them 1) second. We really need some longer WUs now (please, if at all possible).

              [edit]I just looked at BM and I see I have three ready to report that took 0 CPU time. Doesn\'t look like they errored out or anything.

              My biggest concern is server overload if we get bunches and bunches of these WUs[/edit]

                That has something to do with how the SZTAKI DG program reads the WU file after being dumped from memory (either not having BOINC keep things in memory or stopping and exiting BOINC completely). The checkpoints are there so it picks up where it leaves off but actually errors out in the end due to the problem with removing a WU from memory. It\'s been brought up before and Adam is aware of it as it\'s been happening since they upgraded to the BOINC 5.x scripts. It\'s still very annoying even with the small WU\'s since it still takes the full time to crunch and actually wastes the CPU time. I have several of these errored out WU\'s from various having to shut the PC down reasons.

                The other issue mentioned in this thread is due to a series of extremely quick WU\'s that were issued and is unrelated to the 0.00 credit while others get credit issue. You actually get credit for those very short WU\'s but it is something like 0.004235175 and other extremely small numbers.

                    yesterday i also recieved and sent back about 20 work units worth zero credits.. may have been more im not sure... but what i did notice is that they all lasted less than 1 min. therfore i am guessing there may be a bad batch of work units out there and all these zero credit work units will probaly self purge in a day or 2

                      I also have now 2 results (601911, 539432) with 0 granted credits and nonzero claimed credits (approx. 0.5CR).

                      These results marked as Invalid.

                      In \"stderr out\" field the results has something like:

                      <core_client_version>5.3.15</core_client_version> <stderr_txt> Fraction init: input_size=87662 start_pos=61 Kezdes 1. sortol. Fraction init: input_size=87662 start_pos=61 Ujrainditas checkpointbol, 547 sort mar feldolgoztunk es 547 sort kiirtunk Kezdes 548. sortol. Input vege, 1000. sort dolgoztunk fel </stderr_txt>

                      They were paused and restarted I think.

                      All other successful results has:
                      <core_client_version>5.3.15</core_client_version> <stderr_txt> Fraction init: input_size=95662 start_pos=61 Kezdes 1. sortol. Input vege, 1000. sort dolgoztunk fel </stderr_txt>


                      So I think a problem happens when a result is restarted.

                      I have BOINC 5.3.15 and 16 projects.

                      PS: I hope, that developers will pay attention to this situation and will check up it.

                          Success just means that the WU was crunched and sent back w/o problems. However, when the validator runs it compares the (insert minimum quorum here) results. If one doesn\'t match the others, it doesn\'t get credit.

                          Check the Wiki (click on the link in my sig) and checkout \"credits\", \"quorum\", and \"validation\".

                            No idea if important but you (and perhaps other people) have been the last to return the result.

                              Both results have : Validate state Invalid

                              Invalid results caused by interrupted / restarted work are a bug in the project client. I have a bunch of those too, it hits everyone now and then who has more than this one project running on his PC.


                              You can probably reduce the risk by setting

                              Leave applications in memory while preempted? YES


                              It might be related to the problem with the time leak, restarted WUs often restart with 0 seconds.
