Message 22706 - Posted: 19 May 2009, 15:15:07 UTC - in response to Message 22703.  

Now it is working fine with 6.6.28.
I have deleted local preference file ten put again my own pref.
I have set to 5 cpus for my quad in cc_config.xml

Um, can you show us the cc_config...

for 6.5.0 there should be no need to set GPU numbers at all. The only thing you should set, and set to 1, is the flag to use all GPUs ...

Any idea why the optimized Zslip app. for SSE would be about 10% slower than stock app. on an Athlon XP2800, Win. 2000 computer?
I checked it 3 times and it is slower.

I checked it 3 times and it is slower.

It was built with Microsoft Visual Studio 2003. This version was done for testing in the first instance. SSE is only useful for single precision, so it doesn't provide any benefit for MW (using double precision calculations) and one sees the differences between the different compilers/switches used for that and the stock app.
You should try the x87 version (built with an Intel Compiler), maybe that one is a bit faster than the stock app.

Actually, your observation is a clear proof that the stock app is quite good actually (what some people still don't want to believe). The project implemented a lot of the code changes from the early optimized apps so the actual difference of the code is really small now. The factor ~2 (a bit more on recent CPUs, a bit less on older ones) advantage one sees with the SSE2+ versions is caused mainly by the compiler making full use of the SSE2 units (auto vectorization kicking in) and the much more efficient flat register file of SSEx instead of the stack based approach of the x87 FPU.

Message 29223 - Posted: 11 Aug 2009, 21:09:36 UTC

Hi,
for some reasons i had to reinstall my XP-pro. I've installed all available updates for windows, .net and ATI-software.
The first application running on the new system was BOINC. I installed 0.19f, did the copy and renaming in the \system32 directory.
Unfortunately my display-driver says sometimes, that it was necessary to reset the driver, which means, that standard BOINC-project resume ther work, but MW stops processing. It is necessary to stop and restart BOINC.
It definitely did not happen on the old installation, the main difference is the presence of all updates. Hardware is the same (exept another HD).
CCC is version 2009.0702.1239.20840, Boinc is version 6.6.36 and .net is 2.0.50727.3082.
The correct message from the driver is: VPU Recover has reset your graphics accelerator as it was no longer responding to graphics driver commands.

Message 29237 - Posted: 11 Aug 2009, 23:48:36 UTC - in response to Message 29223.  

I am guessing that you installed Catalyst 9.7, we have seen issues with both 9.6 and 9.7 on VPU recovery. So far the safest bet is either 8.12 or 9.5 as both of them seem to keep running with no problem.

Message 29341 - Posted: 14 Aug 2009, 10:23:42 UTC - in response to Message 29237.  

Hi,
yes, you're right. I tried to downgrade to 9.5, but this ugly message came up again. Then i removed all ATI-Software from my PC, removed the graphics-drivers, restarted my system, used CCleaner to remove all the forgotten entries in the registry (there where more than 40 entries pointing to ati-software - what a wonderful uninstaller from ATI! ), restarted again and installed the 9.1 catalyst, which needs no renaming of these three files. And yes, i have also removed the three copied and renamed files.
BUT THIS UGLY MESSAGE COMES UP AGAIN !!!!
Is there anything else that can be done except reinstalling windows?

Werkstatt the problem is ccleaner dont remove residu from system maps
I used driver cleaner in the paste but sadly they gone greedy now and is payed
Thats the only tool which really cleans all crap drivers keep on your system

But also a common mistake people make is not let the uninstaller do its work good, if ati stuff is there select uninstall driver and then restart.

If you can find another good free driver uninstall program we would like to know that as well

Its new, its relative fast... my new bicycle

Sorry to tell you that. I used the ATI uninstall utility, which lets you decide to only remove CCC or ompletely remove all ATI-Software including the drivers.
I did it with driver 9.7 and with 9.5.
Yesterday i decided to reinstall my XP. I installed my old 3850 Graphic card and used the old 8.3 CCC, which was working before the new installation.
I installed the Win_32 SSE2 in the Milkyway directory (latest 0.19 SSE2f Version). I do no longer get the VPU-Reset messages, but all WU report calculation errors.
The difference to the previous system is: a different hard disk, a mainboard bios update and the windows updates from the last 14 months.
I often had troubles with different programs after updating windows; this is why the updates are under suspicion.

The minimum CCC version is 8.12, all others are too old to work with the CAL version included.

Hi,
i think, i've got it!
During a virussscan i retried to run milkyway .. and it worked!
So it seems, heavy system usage solves the problem. I added a w1.1 in the XML-setup file and it crunches since one hour.
hopepully longer ...

I started using CCC 9.8 yesterday and it seems to be working great, using CMDLINE option "f20 n2".

This is using a 3780 under Vista Ultimate X64.

I found CCC 9.8 on the Guru3D.com enthusiast site. Still not available on the ATI support site.

Indeed on any system the 8.12 version is the best for running gipsels MW app except when running vista 64 there the 9.1 or 9.7 driver seems to run fine

I've found this:

http://www.guru3d.com
search for driver sweeper.
Remove drivers with onboard tools, restart in safe mode and use driver sweeper.

Hi,

this is a good source for drivers!

I did the same one hour ago and it seems to run fine witch standard settings. With f20 it hangs within a minute.

Q9300, 3850, XP-Pro, all Updates, no tuning.

one of the tasks can be found here

the task completes normally, so now credit issues or anything significant that I can tell.

In fact SSE2 and up do provide packed double precision operation. (SIMD) so that might provide a good speedup.
See: table B-25. formats and encodings of SSE2 floating point instructions.

Message 30816 - Posted: 14 Sep 2009, 13:19:41 UTC

Finally I found a working combination on XP32.
I have a HD 4870 512MB. I used Catalyst 9.7, 0.19g with SSE2 and calculation is going on without BSOD! I have BOINC 6.10.3.0
Previously I tried:
Catalyst 9.9 with 0.19f sse2, Catalyst 9.9 with 0.20 and Catalyst 9.7 with 0.20.
Version 0.20 downloads only 6 packets and will not begin to work.
