2) Message boards : Number crunching : Computation errors? (Message 49402) Posted 17 Jun 2011 by Volodymyr Shcherbyna Post: http://support.microsoft.com/kb/2005279 I'll see if I can try again with an older version You can contact me in PM to send the updated executable to test. I support my software in 2k, so I have a bunch of tests machine ready to test your changes. It will save some time for you.
3) Message boards : Number crunching : Computation errors? (Message 49394) Posted 17 Jun 2011 by Volodymyr Shcherbyna Post: Well, in fact, the problem is not the same. In *086 I don't see static link to msvcrt.dll. It is dynamic. Therefore this application does not run due to absence of msvcrt.dll in the system. In most of the cases machines are clean and don't have CRT library installed. Can you compile it with static CRT? I.e., /MT switch and not /MD. This will increase size of the binary, but it will make sure people would not have to dig and see what's wrong. In this particular case it is blaming it cannot find the function lc_codepage_func(...) http://msdn.microsoft.com/en-us/library/ff730817.aspx - from VS 2010 CRT ! Thank you!

5) Message boards : Number crunching : Computation errors? (Message 49330) Posted 15 Jun 2011 by Volodymyr Shcherbyna Post: If I see dependency of the binary, I see that it links with EncodePointer!kernel32.dll which is not exproted in 2k. Please see attached screenshot: Actually, if you don't have 2k, you can just watch the import table of the executable and make sure it does not contain EncodePointer & DecodePointer. The simplest solution is to search for occurancy using any test editor. You can also use grep if you up to.
6) Message boards : Number crunching : Computation errors? (Message 49325) Posted 15 Jun 2011 by Volodymyr Shcherbyna Post: Any news on Windows 2000 ? I still can't run the tasks because they fail with "calculation error". I thought I built everything for Windows 2000, but apparently I was 1 underscore off in defining the windows version, and it was missing the version from the link flags. I put out the 0.84 (nonGPU) for 32 bit Windows. That might work, I don't have a Windows 2000 around to actually try it. Thank you. I just tried the updated MilkyWay@Home 0.84 (ps_test_4_1064456_0) and it fails with the same error.

8) Message boards : Number crunching : Computation errors? (Message 46216) Posted 13 Feb 2011 by Volodymyr Shcherbyna Post: I also noticed another glitch in BOINC when running it on my windows 7 machine: one of the task has progress in 127.808%. How is this possible? See screenshot here:
9) Message boards : Number crunching : Computation errors? (Message 46191) Posted 12 Feb 2011 by Volodymyr Shcherbyna Post: So, it has to clearly stated that Milkyway tasks can be run only and only starting from Windows XP SP2. No. In my experience they run with ATI cards on Vista and Win7 and with nVidia CUDA on Vista Ultimate x64. Both are GPU tasks. I have also ran them via CPU on a Vista Ultimate x84 box, without errors. Well, I ment starting from Windows XP SP2 and higher (obviously, it means Vista and 7). However, I still don't know what to do with my Win2000 laptop :) I use it for tests, so most of the time it is idle and boinc is a good fun time for it ... I noticed that tasks started to fail recently. Like 3 months ago. Before it was working okay.
10) Message boards : Number crunching : Computation errors? (Message 46185) Posted 12 Feb 2011 by Volodymyr Shcherbyna Post: No way to solve this problem? If it does not work in Win2000, obviously, it does not work in Win98. So, it has to clearly stated that Milkyway tasks can be run only and only starting from Windows XP SP2.
11) Message boards : Number crunching : Computation errors? (Message 46133) Posted 10 Feb 2011 by Volodymyr Shcherbyna Post: This MIGHT be because I think I built everything targeting Windows XP. If it is encoding pointer issue, it is even worse - they are supported starting from Windows XP SP2.

Thanks This MIGHT be because I think I built everything targeting Windows XP. I wonder, how can i get the executable? I can open it with dependscheck and see what prevents it to be executed. In fact, I just took a look at the milkyway_0.50_windows_intelx86.exe in Dependency Walker and I see that two functions from kernel32.dll are not bound: DecodePointer(...) and EncodePointer(...) Why are you using these?
