That big one requires (3000 * 3500 * 8 * 2 / (1024 * 1024)) = 160MB. Maybe that isn't available? Alternatively ATI's drivers have had (may still have?) problems where they sometimes don't allow you to allocate more than some random size for a single buffer.

Any long task crasched at my HD 4770 @ XP x86. All short tasks are running OK.

The long tasks have been running fine on all 8 of my HD 4770 cards (512k). Using the v10.12 ATI drivers with app support on all of them. All are Win7-64.

"Stream Allocation : Failed to create Buffer" errors are usually caused by insufficient system memory in the Collatz ATI application. Perhaps this could be the cause here also. Hard to tell when computers are hidden.

Could also be similar to what happened about a year ago when the task lengths were increased and the memory in the GPU was not being initialised properly for CUDA cards running Win XP. It was fixed by a new 0.23 version application. If this was the case though I would have expected more people to be reporting these errors.

Is there any workaround for this?

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?

If it is encoding pointer issue, it is even worse - they are supported starting from Windows XP SP2.

I had one wu that just plain stuck and nothing ran all day on my computer. Not sure why. All others have run fine.

Doesn't expecting the unexpected make the unexpected the expected?
If it makes sense, DON'T do it.

I'm not. Something in libraryland must be.

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.

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.

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:

Any news on Windows 2000 ? I still can't run the tasks because they fail with "calculation error".

Any new 0.82tasks crashed.i quid them.

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.

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.

Try 0.86

Same problem with 086:

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!
