      I\'ll post some of my experiences about the 3rd Pan-Galactic BOINC Workshop soon, stay tuned!

        Szia Ádám!
        Ez a munkacsomag miért lett újra kiosztva? Most mindenki uannyi kreditet fog kapni?

          As you could have already experinced new workunits has been delayed for some reason. Well, the reason was that I\'ve been kept promised by the infrastructure team that the new database server is ready. Now, last Thursday I asked them to create the new database for me, so the szdg research team can have a test on it and guess what happened...they came up with some problems and asked me to delay the new database for a few weeks. Hurray!

          I know I\'ve been silent in the past days, sorry for that, I\'ll try to squeeze some more time for better communication.

          I\'ve been waiting with the release of new workunits for the new database, but since we won\'t have it for now, I\'ll release new workunits in a day or two.

            It is good that the Windows/Linux/Mac validator bug has been fixed. Any progress on the checkpointing bug Ádám?

              Not much, but I hope I can get the test facility up and running soon and we can run some tests on this issue.

                Last week I have been dealing with the spam in the user and profile pages. The absolute solution for this would be to finally catch up with and keep tracking the BOINC source repository. Which I cannot do yet, because:
                we run the project server on a Debian operating system and we\'ve installed the server from a Debian package. This package has been created by one of our colleagues. The package is a demonstration for other institutes who might want to run a project, so we can demonstrate them, how easy it is to install a BOINC project.
                The problem is that the package lacks the feature of tracking the changes in the BOINC source and is created from an older version of BOINC (which used php4). Due to package dependencies I could not upgrade php 4 to version 5, which also causes some troubles on the homepage.
                Hopefully, this will soon change and SZTAKI Desktop Grid will finally get ready with the new package and be able to keep track with the changes in BOINC and enter the proud group of full featured BOINC projects.

                Up till then, I\'ve manually installed the captcha on the profile pages to fight the spammers and also make the necessary changes on the account creation form, when the BOINC guys have decided how to do it.

                  Hi,

                  early July we had a talk with the mathematicians from ELTE university. We\'ve come to an arrangement that if we could improve the communication between the two institutes, it would much improve a lot of things including the answering of user questions regarding the application. We\'ve created a new communication channel or if you prefer mailing list :) that will be read by the bosses of both institute as well. This will hopefully make things more fluent.

                  The other thing we\'ve talked about is that dimension 12 is soon to be over, so we will start testing dimension 13 on the test grid. The mathematicians have informed us about, that the current algorithm is capable of handling any dimension, but the constant term (another important parameter of the application) can only be two. This is good news for the project, meaning we will have work for quite a while.

                  They are also working on a new algorithm, saying it will be ready by September, that will open the door in front of increasing the constant term variable as well. They have presented us the current results gathered in a matrix. This matrix presents the found expansive polynoms and the canonical number system base polynoms in regards of the dimension and the constant term. Currently this matrix is more likely an upper-triangle matrix, meaning that they already have everything up to dimension 8 and constant term 10 and it\'s up to us to complete this matrix, by computing the missing parts.

                  Hopefully, I will be able to present this matrix soon on the homepage.

                  I\'ve also asked them the user question asked the most: What are the results good for? And the answer goes like: the results are more likely to be theoretic. However, noone else on planet Earth is working on this, but the results could and will be used by many other researches. The plans of the mathematicians is to present results publicly to the whole world as soon as they are ready.

                    Replying to the condition, that some of the workunits of the 14th dimension tend to be much larger than it should be in an optimal situations those workunits that have not already been sent out have been canceled.

                    I couldn\'t cancel workunits in progress, because that could result in claimed credits not being granted. These workunits will hopefully return soon opening the way in front of the newly generated workunits, with lowered input lines and lengthened deadline. New workunits can be recognized of the deadline of 30 days.

                    Meanwhile, the results of big workunits will be processed by hand and any claimed credit will be granted.

                      The newer version of the server has the ability to cancel WUs without damage. If the task has not yet started crunching, it the client will cancel it. Otherwise it is left to complete normally and credited normally. Also, the newer server would recognize modern versions of the operating systems (XP64, Leopard, etc.)

                        That is true, but to install it we need a Debian package of it (it is...well, policy). I will ask the expert on this topic to see how much work would that be.

                        Meanwhile, the new workunits seems to be of reasonable length. There are only 3 returned results that took more than 24 hours to process out of 1800.

                          Any update on when this will happen? Will it apply to the WUs that failed with computation errors after many days crunching and reported incorrect CPU time?

                                Unfortunately, things are worsening again. From the 17 WU I got this week for my Quad Q9300, 4 returned already with more than 21 hours, three further WU running at the moment will also be long runners - they have already reached 32 hours (80%), 14 hours (60%), and 12 hours (20%). (Percentages after restarting the WUs.) And I assume, that a Q9300 is faster than the average cpu today.

                                  I have seen results of your manual actions regarding credits. But at this time there is a strange situation with the credit granted to me. In total the credits are 3741 but when I am looking to my computers it is telling a complete different story. One computer that was active during the last 30 days has 5477 credits and the other one (not active during the last 30 days) has 2994 credits.

                                  Computer id\'s are 295783 and 295947
