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..

//Vyper

guido.man:
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
Started at  : 13:31:12
Device name: GeForce 8800 GT
Device version : 1.1
Total global memory: 255 MB
Shared memory per block: 16 kB
Registers per block: 8192
Warp size: 32
Max threads per block: 512
Shaders clock rate: 1512 MHz
Generated FFT plans
mem alloc
Copying chirped data (chirp rate=0) ...
FFT s:8 bs:131072 > Finded spikes > Transposing

Seems to hang on my system anyway.

Cheers.

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?
