Hmmm, interesting.

Ok, I took Richard's renamed files, copied them and renamed the copies back to the original 32_30_14.dll and put all four into my SAH folder. This time nothing errored out but one work unit that had started before I did this would not restart. I let it try for two or three minutes but the percent did not move. I suspended that one and the next in line started with no problem. For grins, I suspended that one and it went back to the first one. Again, after about two minutes it still had not started so I aborted it. It picked up on the second one where it had left off and is running fine so far.  As for speed, I seem to have sped up a few seconds with this new driver so I guess I shall stay with it.

Sutaru Tsureku:
Ohh well, maybe a stupid question.. :-[

How should look the app_info.xml?
What's needed to mentioned?

This would be well?

--- Code: ---.
.
<file_info>
<name>MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe</name>
<executable/>
</file_info>
<file_info>
<name>cudart.dll</name>
<executable/>
</file_info>
<file_info>
<name>cudafft.dll</name>
<executable/>
</file_info>
<file_info>
<name>libfftw3f-3-1-1a_upx.dll</name>
<executable/>
</file_info>
.
.
--- End code ---
The same in the <file_ref> part?

Or I need to insert the other 2 file names, cudart32_30_14.dll and cudafft32_30_14.dll ?

Thanks! :)


BTW. Maybe we would see more speed up, if the current MB_6.08_CUDA_V12_app would be new compiled with the new CUDA V3.0 toolkit/or other prog?
I guess in near future it should be done for the new Fermi chips, or? But if we would see also speed up with the 'old' hardware?

Pepi:
Your app.info is OK, you dont need to change anything. It will work fine.

Sutaru Tsureku:
IMPORTANT!
The .dll files must be named:
cudart.dll
cudart32_30_14.dll
cufft.dll
cufft32_30_14.dll

The fft files without 'da'!

If you write cudafft.., you will trash your DLed WUs.


Hey guys..
I thought I'm stupid.. I'm crazy..
I done this and this, tested this and tested this..
CUDA V3.0 didn't worked.

Then I 'installed' the CUDA toolkit V3.0 and saw that the .dll file is named different.
Like the CUDA V2.x .dll's.

Next time I'll not believe all immediately what I read.. ;)

Now it work 197.13 and CUDA V3.0.14 .
Will look how the calculation times are..

glennaxl:
You only need to duplicate the RT.
So it would be like this:
cudart32_30_14.dll
copy of cudart32_30_14.dll -> rename to cudart.dll
cufft32_30_14.dll -> rename to cufft.dll


Here's some good stuff. Some improvement (1%-2%) with 197.13 compared to my last test.

driver : 197.13
CPU: 100%
GPU: gtx 295 core 0
