Latest drivers (NVidia and ATI)
Sutaru Tsureku:
But, ..maybe stupid question.. :-[
Why I need at least 3 .dll files of CUDA V3.0 instead of 2 like in past with CUDA V2.3?
If I don't count the libfftw3f-3-1-1a_upx.dll .
Why not useage only of cudart32_30_14.dll & cufft32_30_14.dll (original named) and change the entries in the app_info.xml?
Richard Haselgrove:
Because the application (SETI MB CUDA) only knows the names "cudart.dll" and "cufft.dll".
But the new v3 cufft.dll expects to have "cudart32_30_14.dll" available.

If we can get it recompiled using the latest toolkit we wouldn't need to do this, although it would need testing. We might even be able to get a 64 bit version, although i'd doubt it would offer any speed advantages.

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

Which nVIDIA driver you tested with CUDA V2.3?
I guess you used only 197.13 with CUDA V2.3 and CUDA V3.0.14 in your test, right?
I have the feeling that 197.13 + CUDA V3.0.14 is ~ 1 - 2 % slower than 190.x + CUDA V2.3.
Have someone tested this driver/CUDA combinations?

My test was CUDA v2.3 vs CUDA v3.0.14 on MB_6.08_CUDA_V12_VLARKill_FPLim2048.exe
