GPU client

[Devaster]

No no , CUDA application is living but code for other GPU is abadoned ....

[Jason G]

Ahhh , I see! no probs! As you were then

Any reason for abandoning the other app?

When i tested it I got an error 9 as many others.

Is the pre-8xxx hardware that bad for these kind of things?

Just so sorry to hear as i own an Nvidia 7950 which i bought just half an year ago with my new computer.

[Devaster]

i have time only for one project and code for pre8x and 8x card is totally different ....

now working on populate PoT functions ...

[Devaster]

new code ...


- small change in findspike - no speedup better validation only ....

After running for 45 min no progress had been made... (still sitting on 1st fft (size 8?))

Is sahcudagpu10.zip for G80 only?
Will not work on EN8800GT   G92.

[Vyper]

No its for all G90+ all from 8500 and up..

Well ran latest code sahcudagpu10.exe

code runs on cpu at 100%, gpu card does nothing.

This is all I get

Running app : sahcudagpu10.exe with -verbose
with WU     : testWU-1.wu

Shaders clock rate: 1512 MHz
Generated FFT plans

Copying chirped data (chirp rate=0) ...

Seems to hang on my system anyway.

Cheers.

"The application has failed to start because cufft.dll was not found. Re-installing the application may fix this problem."

Actually you need to have all needed DLLs of that CUDA runtime consist in place searchable by OS for DLL (simple saying in LIB_PATH). If you use CUDA only for SETI probably better way to put that DLLs together with exe file. When I tried CUDA few months ago the needed DLLs list was cuda.dll cudart.dll cufft.dll cutil32.dll (maybe slightly redundant).

Hi All,
I'm having difficulty getting the sahcuda client running due to library path problems.
I've installed Nvidia cuda sdk v0.81 and Cuda toolkit v0.80.0000 to the same directory
I've checked the Cuda paths in Environment variables and they seem fine.
I installed the sahcuda.exe into the same directory but I still get a "cudart.dll was not found" error.

CUDA_LIB_PATH=C:\CUDA\lib
CUDA_BIN_PATH=C:\CUDA\bin
CUDA_INC_PATH=C:\CUDA\include

Card: Evga 8800 GTS 512


How can I solve this problem?

[Vyper]

I can understand why you have problems..

Download the latest as found here http://www.nvidia.com/object/cuda_get.html.

Cuda is now up to version 1.1 and that version u have doesn't even support large CUFFT calls.

Kind regards Vyper

Hi Vyper, Thanks for the reply,

The version I have installed is actually v1.1 (X86-64 for XP-64bit) . The version reported under "support information" in Add/Remove programs is incorrect.

Nothing more happen. Same as the others.

[Vyper]

Hmm this is odd really. Have you tried the previous versions compiled by DevasteR?

I've tried them out by myself and they used to work properly.

U might need VS2005 addon in some sort but it don't know the name of that file atm, think it had to do with some asm functions or so?

Kind Regards Vyper

[Devaster]

last exe is broken .. sorry
