I have spotted a bug (during the closed beta of F@h) that if the person aborts a WU via gui and the new WU has a later application version, the new science applciation is downloaded but the current (older application is used. The bug is reported at http://bbugs.axpr.net/bug.php?op=show&bugid=202 If you need any additional alpha people drop me an email.

I had problems with 4.24 with signature errors, a simple reset fixed this issue. Now running 4.26 now and havent seen any signing issues.

There was issues with the earlier v4.2x versions but these seem to be sorted.
4) Message boards : Number crunching : Boinc Client 4.25 (Message 6504) Posted 8 Mar 2005 by PeterHallgarten Post: http://www.ssl.berkeley.edu/pipermail/boinc_projects/2005-March/000831.html I'm pleased to announce the 4.25 release of the BOINC client for Windows. The highlights for this release are: 1. A MSI based installer, for large scale deployments. 2. A new task based GUI which utilizes the wxWidget cross platform framework, so we could use the same GUI code for the rest of the platforms. 3. Installation options for running in the shared and service execution modes. 4. A more comprehensive set of GUI RPC's for management of the daemon. 5. Abilities to suspend/resume projects. 6. Abilities to suspend/resume results, even ones which haven't started executing yet. 7. Abilities to abort results. 8. Abilities to abort transfers. 9. Abilities to add URLs to the GUI Interface on a project specific basis. 10. Supports multiple messages returned from the scheduler. We would like to thank the Alpha testers and the various community members who reported bugs and helped us smooth out the rough edges. We are still cooking the Linux, Solaris, and Mac versions which should be showing up in the next week or so. ----- Rom BOINC Development Team Space Sciences Laboratory University of California, Berkeley

I am one of the alpha test people on the E@H alpha test. It is still in pre-release alpha, they have just upgraded the server side and are working through the issues. They have been issuing WU to the alpha test people for a little while now and are still working on the scientific side. The people involved are people closely associated with LINGO/GEO or selected alpha testers. Once this phase is conplete they plan to add a limited number of more general users. As they say watch this space. Here is a grab of the current screen saver for E@H Windows Client V4.31 http://www.vk3ave.webhop.net/EatH-AlphaTest.JPG 73 de VK3AVE
7) Message boards : Number crunching : fortran error.. (Message 4808) Posted 2 Nov 2004 by PeterHallgarten Post: I just got the same fortran error after lots of 4.47 work units. First error in ages... System is Windows XP SP3 Intel Mobile Pentium. Running the Boinc 4.53 alpha quite happly here...

Boinc is the source for boinc 4.5 the new split gui and cli compoent and boinc_public is the source for the current boinc 4.11. 73 de VK3AVE
10) Message boards : Cafe LHC : So what's going on with LHC@home anyway? (Message 3242) Posted 5 Oct 2004 by PeterHallgarten Post: Hi, Reading around the project people, it seems that they have some issues with the capability of the machine that is running the database server and also databse type, indexing etc. It seems they are getting good advice from the various boinc project people. It takes time to rebuild servers, transfer and rebuild databases etc escpecially iona live system. We all look foraward to a better more stable LHC.
11) Message boards : Number crunching : Server problems (Message 3144) Posted 3 Oct 2004 by PeterHallgarten Post: Hi All, As a person that works in the IT industry on all sorts of scales of projects, it is sometimes hard to fullly spec the requirements as a system that grows, ie. how many servers do I split the various components of the system over, what are the server requirements and specifications. We also have to relise that Boinc is new as well and its design is still evolving and only by putting the the process of large scale projects liek Seti etc will bugs be killed. I looked at seti and they are spread over 5 servers and are processing: "State Approximate #results Ready to sed 1,262,222 In progress 3,966,013" This is a huge amount of data to handle. Reconfigurations of running live systems are very complicated and my hat is off to the technical support people at each of there projects. 73 de Peter VK3AVE
12) Message boards : Number crunching : Fortran Error/Computation Error (Message 1862) Posted 22 Sep 2004 by PeterHallgarten Post: Hi, I have got two WU so far that have errored... The error occurs wheen the WU is 100% of processing. I get a popup box labeled Fortran that have an Information message saying "jwe0019i-u The program has terminated abnormally with Exception Code ECEPTION_ACCESS_VIOLATION" and has an OK button Pressingf OK gives another Fortran Inforamtion Box with "Error summary (Fortran) error number jwe0019i u 1 total error count = 1" and has an OK button. Pressing ok give a Computation error on the WU. WU was v64lhc1000pro3s14_16544.46_1_sixvf_15479_1_0 ( http://lhcathome.cern.ch/result.php?resultid=151928) Stderr.txt says "2004-09-22 19:53:45 [LHC@home] Unrecoverable error for result v64lhc1000pro3s14_16544.46_1_sixvf_15479_1 (The session was canceled.

13) Message boards : Number crunching : Linux/Graphics (Message 1541) Posted 20 Sep 2004 by PeterHallgarten Post: The climateprediction is a saperate addon that you run from a shell script that talks to the boinc interface and does the impressive cliamteprediuction graphics. Is nice to see soemtimes how the process is going in graphics. I have got some of the linux boinc viewers and they some of the windows gui interface. All good things take time to improve, and you guys have a lot in the startup to control. 73 de Peter VK3AVE
14) Message boards : Number crunching : Linux/Graphics (Message 1535) Posted 20 Sep 2004 by PeterHallgarten Post: I am intested to see if they include some sort of xwindows interface, climateprediction does, but seti@home doesnt... I am also waiting oin the linxu client as I ahev two machines here that will munch linux LHC units.
