Need help for CUDA-Multiforcer(CUDA Error)

[Reaper]

Hi dudes,
i have some problem with the latest CUDA-Multiforcer. I test it on a 64-bit Linux(Ubuntu v10.10) System with 8GB DDR3 4*2,4GHz and an Nvidia 240GT. The configuration of the Multiforcer is :
./CUDA-Multiforcer-CPP -h MD5 -f Hashes-MD5-Numeric.txt -c charsetlowernumeric --min 1 --max 8

I get "Cuda error in file 'CHHashTypePlain.cpp' in line 136 : all CUDA-capable devices are busy or unavailable."

I had installed the latest NVIDIA Driver (v260-19-29).

Please Help

Are you using alpha4?

If so, run it with the '-q' command switch to report available devices and see what it prints out.

Hi Bitweasil, thx for the fast reply. Yes i'm using the 0.8 alpha version.

when i run the -q command he print my 240GT device:

CUDA Device Information:
Device 0: "GeForce GT 240"
Number of cores: 96
Clock rate: 1.34 GHz
Performance Number: 128640
Note: Performance number is clock in mhz * core count, for comparing devices.

But i can not execute the multiforcer.

And nothing else is running that would be using CUDA?

Do you have compositioning turned on in X11 or such? If you can kill X11 and try it from the command line without X running, that would determine if it's a conflict.

# nvidia-smi -g 0 -c 1
# nvidia-smi -g 0 -c 0

Try that too as root - it toggles the device in and out of exclusive mode and may help clean up any weird stuff that was lingering.

I've never seen this error before - it's a stock CUDA error. I did find some google hits for it, you might want to try those. It seems like a driver/OS issue, not a multiforcer issue.

Any luck?
