CUDA 3.0.14

[glennaxl]

CUDA 3 is finally out.
Download Link.

It doesn't seem to have that much of an improvement - 1% increase.
Here's my test:
driver : 196.75
CPU: 100%
GPU: gtx 295 core 0

Hi ,  after I put in a 2nd nVIDIA card, The OS (WIN XP64) immediatly responded and downloaded the latest drivers and CUDA 3.0.14.

I tried CUDA 3.0 before with driver 196.68/75 with the 9800GTX+, which became/was unstable.  And no  speed gain. (Could have been BOINC 6.10.18, too.) Using 6.10.17 now.

After adding a GTS250 (also a G92 chip), I downgraded the driver to 190.38 and CUDA 2.3 Libraries. After inserting a cc_config.xml, with use_all-gpus, as option and some debug-flags. (coproc; xfers), put a 2nd monitor to 2nd card an extend the desktop, to it. It works OK, after removing the 2nd monitor.

On my GT 240 it doesnot work- computation error!
So what part of CUDA 3.0 you use? And how?
Last time ( with beta 3.0) it was like this

What one needs to do to use current CUDA MB builds:
use fully named cudart DLL (that is, not cudart.dll, but cudart32_30_8.dll )
 and use renamed CUFFT DLL (that is, rename cufft32_30_8.dll to cufft.dll ).
Of course I renamed files accordingly new names

Good question. I wasn't paying attention to the error that I got but instead I used both, the original name and the renamed one.
like this:
cudart32_30_14.dll
cudart.dll
cufft32_30_14.dll
cufft.dll

BTW, are you using CUDA 3.0 capable driver?

[Pepi]

In that case  I am 100% sure that you dont use new drivers at all. Of course I use 3.0 capable driver ( 197.13)
Remove old drivers cudart.dll and cufft.dll and you will get computation errors.
So what is left is try to use new dll with stock application.
update: it doesn't work. It looks like cuda 3.0 dll are not compatible with current cuda app

197.13 is a beta driver. I use 196.75 which they removed it from production.

To make it clear here's what I did:
cudart32_30_14.dll
cufft32_30_14.dll
copy of cudart32_30_14.dll -> renamed to cudart.dll
copy of cufft32_30_14.dll -> renamed to cufft.dll

If use your method it works

The same way it works for COLLATZ!
Filename here: "cudart_CUDA23.dll"

Something amiss with 32bit and 64bit downloads. The 32bit rt and cufft part in 64bit installer has a diff file size.

64bit installer:
cudart32_30_14.dll = 273KB
cufft32_30_14.dll = 12403KB

32bit installer:
cudart32_30_14.dll = 280KB
cufft32_30_14.dll = 12188KB

Code guru's, can you comment on this?

The CUDA_V3.0_final have improvement/speed up compared to CUDA_V2.3?

Someone made a test if the newest nVIDIA_driver & CUDA_V3.0_final is faster than nVIDIA_driver_190.x (or 191.x) & CUDA_V2.3 ?

Thanks!
