    As you might have already noticed the [ulr=http://szdg.lpds.sztaki.hu/szdg/img/uc-demo/dtg.html]description[/url] about the new physical application is available on the homepage.

    Should you have any questions regarding the application, please post your questions here.

      How can we choose to run one project or the other and are the new WUs available?

        Hello Adam,
        when will this new App be available ?
        Will the Wus be big ones ? (Time, ram, etc...)
        Any screensaver ?
        Any idea about the time we will spend on this new project ? (how many Wus...)
        Thank you.

          We are currently working on compiling the application code for several platforms. Hopefully, this will be completed this week and we can start the new application.

          This application is more deterministic regarding computation time, so there won\'t be so much fluctuation as with the other application. Preliminary tests showed that a workunit runs about 3 hours on a Pentium 4 processor.

          There will be lots (like millions) of workunits for this application. The workunit distribution will be random among the two applications, but the other application will likely to be suspended to address problems that has been reported.

          There is no screensaver in schedule yet.

            May we have an option under project preferences to choose which application we wish to run? Other projects (such as Yoyo and PrimeGrid) provide this choice. Also will we be able to run this application on 64bit machines?

              Upgrading the server BOINC software is way past due. Why not take the opportunity to do it too?

              Thanks.

                  I would like to repeat this request. As it turns out the old search WUs run very well on AMDs while the new uc-explorer WUs are horrible. Please give us a way to choose which project to run. Thanks.

                    I would like to second this request. I think it would improve your project\'s standing and bring in more crunchers.

                      Should you have any questions regarding the application, please post your questions here.

                      Yes - I have one question regarding these new UC-explorer WUs...
                      Why is Linux-OS so much slower than window$-OS (up to 12 times slower) ??
                      If you look at this WU (wuid=2328034) , you can see that I needed over 10 hours using Linux-OS, while my co-crunchers used Window$-OS and did the same WU in 50 minutes.
                      Sorry, but I can\'t run this project if this is going to be the normal behavior - It\'s clearly that my Linux-computers can do much better work elsewhere - I\'m out of here....until this matter is sorted out...

                        One problem is that you\'re running an AMD processor. The new application is horrible on AMDs (but it\'s true that the situation is MUCH worse with Linux), unlike the old application which ran very well on AMD. That\'s another reason to allow us to choose which application we would like to run. I\'ve also moved my machines elsewhere until there\'s a reasonable resolution.

                                Hi, sorry for the longer silence, but I was abroad. Upgrading the server is a pain because as a request from the management we can only use a Debian package of the server. However, this package has to be hand-taylored, whenever we want to upgrade the server. There is an initiative to help the BOINC repository to be more Debian friendlier, but this goes slow.

                                The AMD problem is under investigation and also I\'ll try to impinge on the management to upgrade the server to a WCG-like one, where you can choose which project to participate in.

                                64-bit Windows is a problem, because we would need the Pro version of the Visual C++ compiler to compile on 64-bit. I\'ll try to compile with Mingw, which is free and theoretically can compile 64-bit binaries as well.

                                  As I understand it all you have to do is allow the server to send the 32bit apps to 64bit clients. No re-compiling needed. That\'s exactly what most projects do.

                                    Tell them about all the security holes with the version of BOINC they are currently running. Seriously.

                                        Hi, we just had a meeting with the management and the following decisions were made:

                                        1. selection of the application by the user won\'t be available until more than two applications are available, because the physics application cannot serve enough work packages in case the majority of users would decide to support only that.

                                        2. Upgrading the server code has been made a priority for the administrator group and they shall begin it as soon as other priority jobs have been finished. Unfortunately, as I understood they have plenty of work to do before the upgrade can begin.

                                          Hi everyone.
                                          So if I understand this correct we x64-folks have to wait for the server upgrade before we get the 32-bit Windows app delivered to 64-bit machines?

                                          When I saw the news I re-attached my x64 lappy but I still get the \"platform \'windows_x86_64\' not found\" message. ;-)

                                            1. selection of the application by the user won\'t be available until more than two applications are available, because the physics application cannot serve enough work packages in case the majority of users would decide to support only that.

                                            But to me it comes down to giving UC-Explorer a chance or not, since NumSys is downright buggy. If I cannot chose to not run NumSys, then I cannot crunch any Sztaki WU whatsoever. My systems have better things to do than to crunch WUs that never end or that are not granted any credit at all after hours of computing power thrown at them.

                                              Now when will the Windows 64-bit apps finally be available for download???
                                              I see them (both) listed under \"applications\" but all I get is the dreaded \"platform \'windows_x86_64\' not found\" message... *grumble*

                                              EDIT: The one for Universality Classes Explorer is even new (from today!) but who the heck is getting this app when BOINC persists on telling there is no Win x64 app? *sigh*

                                                When the server upgrade happens, it will automatically sent 32 bit apps to 64 bit machines.

                                                  I had feared that answer... it will take ages before that upgrade will happen I guess.

                                                    Hi, we just had a meeting with the management and the following decisions were made:

                                                    1. selection of the application by the user won\'t be available until more than two applications are available, because the physics application cannot serve enough work packages in case the majority of users would decide to support only that.

                                                    2. Upgrading the server code has been made a priority for the administrator group and they shall begin it as soon as other priority jobs have been finished. Unfortunately, as I understood they have plenty of work to do before the upgrade can begin.


                                                    I signed on to work on the number systems project, not on the physics project. I won\'t be doing any crunching for you until I have some choice in the matter.

                                                      I think a lot of people feel this way. It would help a little if at least the due dates on the physics WUs were the same as the search app. Right now the physics WUs keep preempting the search WUs, very irritating. The real answer of course is letting us choose the project we want to run.

                                                        Hi, Adam!

                                                        How about an update on the decision to not allow us to choose the projects we wish to work on?

                                                        I\'m quite disappointed that there appears to have been no further comments since my last post on this subject.
