    I looked at my returned results and found that one was marked as invalid: <a href="http://szdg.lpds.sztaki.hu/szdg/result.php?resultid=1221">1221 </a> (assuming Érvénytelen=Invalid?).

    Looking closer at the WU I see that one result was marked as Valid (1222) and two marked as Invalid (1221, 1225).

    My unscientific guess is that 1221 &amp; 1225 are the valid ones and 1222 is invalid.

    Can someone from the project team check this out?

    [EDIT]
    1 LINUX vs. 2 WINDOWS clients. This could also point to a (precision?) bug somewhere in the science applications.

      <a href="http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=181">I got one as well.</a>

      It's because one person has crunched it already and gotten credit. All the others after that bringing it in are outside the quorum of results as far as I can see, thus they get zero credits.

      Is the GD quorum of results still set to one?

        I see results piling up that have all results starting to come in invalid.

          I have one result which credits and 4 others without.
          Host 1707

          What i saw is that if the clients running on windows got credits
          then clients with linux got none.
          If the linux clients got credits then the windows clients got none.

          I have WUIDs where 4 got credits and.
          The one sending back later got credits too.
          http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=187

          This one which i did not the sent back first bur got credits..
          http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=1

          An other example
          http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=178
          the one with 0 is running linux the others Windows.

            http://szdg.lpds.sztaki.hu/szdg/workunit.php?wuid=221
            Linux-machine was faster.

            Other results with 0 credits which i found and where not
            from different platforms had an error in the result, like that:

              Ok...that is lame. Considering that I have 17 GB of space and put in my preferences to reserve 1 GB even though all together all the projects take up less then 10 MB.

              Edit: That's 1.0 MB "1000000.000000" not 1.0 GB 1000000000.000000, I believe...

                  I changed them all to nothing. I don't see any of these projects doing any hard drive filling so I will chance it for now just to see what happens. Still there are not enough zeros in

                    Okay, try some other numbers:
                    No more than 2 GB.
                    at least 0.1 GB.
                    No more than 50%.

                    By saying you give it no more than 2GB, with the lower level also at 1GB and to use no more than 50% of that (500MB), you are making it extremely difficult for Boinc to run.

                    It's not really using these amounts to store the work units in, it's using the amount of disc space to work in. So as soon as the work unit uses more than one of the restrictions, it quits with that error.

                      This may sound silly , but check task manager and see if "blender.exe" is running.

                      I had the same failure for a bunch of seti units that the blender.exe crunched the other day.

                        It's not blender and its not the settings. Settings are now off so it is not the disk amounts.

                        8/2/2005 3:13:29 PM|SZTAKI Desktop Grid|Aborting result 1990b328-d735-4fcf-92d0-cb8d316e727f_2: exceeded disk limit: 1000513.000000 &gt; 1000000.000000

                        This line above says that the setting is 1MB and that I have exceeded it by 513 bytes. 1000000.000000 = 1MB. That is an impossible setting as this wu needs at least 1MB to run.

                        I am not the only one since some of the wu's I crunched have other systems and users with the same problem.

                          This is going to drive me insane. The really bad thing is my systems spend up to 2.5 hours crunching a wu on this and them BANG it errors out. A waste of 2.5 hours.

                                I still have no idea what is going on with this. Sometimes they go through and sometimes they don't. I see other users with "computation errors" and some have success with 0 credit being assigned.

                                  Do you have 10GB free on that harddrive? If you don't, you can't set it as the upper limit.
                                  If you don't have 5GB free on the harddrive, you can't set it as the lower limit.

                                  50% of between 10 and 5 gigabyte is still 7.5GB, do you have that amount free?

                                  Check what actual amount your harddrive is, what amount of free space you have on it, and go from there? Set the lower limit to something like 0.001GB

                                  As far as I can see, the 1000000.000000 is the gigabyte boundary. Decimal then, not hexadecimal (1000 against 1024).

                                  Now, you may add that WIndows can't address anything higher than 4GB of memory space. I don't think it's a boundary in Boinc, but you never know. Try setting the max at 4GB, the min at 0.0001GB and the percentage at 50% between them.

                                  If that doesn't work, the questions to be answered are:
                                  Which Boinc version?
                                  Self built?
                                  Are you Overclocking your computer?
                                  Have you tried uninstalling, rebooting and reinstalling Boinc?

                                    You can certainly set the upper limit larger than the HD size. I have a couple of machines with 1GB HDs, and also have some machines with &gt; 100GBs. I have my limit large enough for CPDN to work on the larger HDs (CPDN takes more than 700MB / WU).

                                      I have reinstalled, changed all preferences to all suggestions in this thread. Sometimes it fails.....sometimes it does not WITH THE SAME SETTINGS. I have been first to return results and I have been last. So far no version of BOINC has made a difference and there is no other current similar symptom other then the fact that 1000000 is equal to 1 million which is 1 MB (or close to it). This error-

                                      -is not even a correct statement for any of my machines. Time to finish does not seem to matter since some have taken an hour or two and some have gone over five hours. The fact that some of the ones that were successful actually took up more disk space makes it even more incredible. Seconds to finish does not matter...some around 6000 some over 10000. I don't know what to do but suspend any downloads or crunching for SZTAKI until Adam takes a look. I am not overclocked or overheating or anything. These systems are running the same as they did with dimension 10. Pretty much anything you can think of I already did.

                                        Each work unit has a maximum allowed amount of space that it is allowed to take. If it takes more than this (even if your computer has a lot more allocated) it will error out. There are a few possiblities. The first is that the developers have set this to be too small for some cases. The second is that your computer is having trouble with the calculations for some reason (overclocked, overheated, bad ram, bad CPU...). The third is that WU is mal formed for some other reason.

                                        There isn't much that you can do about the first and third reasons. If it were the middle reason, I would expect that some of the other projects would be giving you some trouble as well. If there are other projects giving you trouble, I would get some program to trace down the bad component(s) in your system. If you are overclocked, reduce the overclocking. When was the last time you chased the dustbunnies out of your CPU case?

                                          If it was a bad component then it would cross at least 5 machines all having the same issue. Most are Dell's and are impossible to overclock. None have a heat issue. None have a problem with any other project. I am starting to wonder if the thing is calculating other projects space, although that shouldn't make a difference.

                                            Our WUs are validated to use no more than 32MB. We have receantly discovered that in some special cases the application tends to create a snapshot of its own state too frequently, of which a log is created and that log can grow bigger than 32MB when the client executes the app in pain. We will try to reproduce the case and come out with a new version of the app that solves this problem in a few days.

                                              Any luck on fixing these issues? I still have machines that have about a 50/50 ratio to either be fully completed wu's or computation error.

                                                  Apparently this is not a new bug. I have seen predictor and lhc forum posts about it and haven't seen any fixes on their sites or any thing else I can do other then manually changing the client state xml file for each wu downloaded but that takes a whole lot of work to do.

                                                  Things I know it is not.
                                                  I have used every boinc client known to man. I stuck sztaki on a new client and it happened. I have reattached a lot. Deleted all files related to sztaki.

                                                  Things not tried.
                                                  A single machine only running sztaki and not any other boinc project. May try that tomorrow with a new machine but that looks highly doubtful to work.

                                                  Read this thread before you give any advice. Every setting known to man that I can set including a custom boinc client build has failed. I get about a 40% return on crunched wu's. Seriously the wu's go to 100% complete and then error out and that sucks my ass.

                                                    I have narrowed it down to machines under 1 GHz that get this error. Bleah!

                                                      Well I still have problems with faster machines...just not as frequent. In order to make sure it wasn't something I did I reloaded a 550MHz Xeon box with XP and it consistently has a computation error. I also loaded a P4 2.0 GHz and it has about a 50% success rate. BOTH were fresh installs with only BOINC and Sztaki loaded.

                                                      HELP!?!?!?!

                                                        From the looks of your log, BOINC is set to use no more than 1M of disk space which can not be correct as no project would be running. Here is how I have my general setting for memory and disk usage:

                                                        Use no more than; 100 GB disk space
                                                        Leave at least; 0.1 GB disk space free
                                                        Use no more than; 50% of total disk space
                                                        Write to disk at most; every 200 seconds
                                                        Use no more than; 90% of total virtual memory

                                                        My HD's are ~60-80G so the first 2 cover things fine. The "use no more than" is more the key. On a 60G HD it will use no more then 30G, no chance of that ever happening on BOINC. Giving it room to breath will just let BOINC do its thing.

                                                        The only memory issues I have had with BOINC were with BURP running at 325M of RAM.

                                                          Not much news here. If we can't figure out something than I'll turn of logging in the apps and release a new version next week to come over this prob.
