can i use cuda without cuda-enable video card can't make correctly in emulation mode

Accelerated Computing CUDA CUDA Programming and Performance
1

My system is ubuntu 8.04
The cuda toolkit is 2.1

I am try to use the cuda on my laptop which don’t have a cuda-enable video card. I only want to use emulation mode.

Because my video card is not NVIDIA, so I can’t install the cuda driver.

After I install the toolkit and SDK, I try to make(make emu=1) it on the folder of NVIDIA_CUDA_SDK, failed.

I try to make(make emu=1) in the subfolder(NVIDIA_CUDA_SDK/projects/scan/), it can make successful. but can’t run the program.

Could you please give me a piece of suggestions.

Can I run cuda without install the driver?

thanks for any reply!

Cheers,

Peter,

try to compile the SDK with
“make emu=1”

compile example projects also with
“make emu=1”

Thanks for you attention.

I do use make emu=1.

4

Could you post the error message when you run the program?

Thank you again!!

first of all, I am a beginner of linux. When I make the SDK, it has some errors.

When I run the program which compiled correctly.

[codebox]shong@shong-desktop:~/NVIDIA_CUDA_SDK/bin/linux/emurelease$ sudo ./bitonic

./bitonic: error while loading shared libraries: libcudart.so.2: cannot open shared object file: No such file or directory

[/codebox]

When I add the /usr/local/cuda/lib to /etc/ld.so.conf and run ldconfig

these errors still exist.

By the way, when I only type ./bitonic, other errors occur. Oh my god.

[codebox]shong@shong-desktop:~/NVIDIA_CUDA_SDK/bin/linux/emurelease$ ./bitonic

Try to solve the first problem by installing libXi and libXi-devel packages.
After that, you should find /usr/lib/libXi.so and /usr/lib/libXi.so.6.

This looks like a known Ubuntu ‘feature’ where it reinstalls its own (96.43.05) driver after every reboot. This ‘feature’ has been discussed, with a solution, elsewhere on this forum.

Thanks!

I installed the libXi.

[codebox]

sudo apt-get update

sudo apt-get install libXi-dev

[/codebox]

The errors still exist.

Thanks you all reply!

I think I should know more about linux.

Thanks.
