how to run or execute cuda program

Learn by Example (CUDA Programming Part 1)

Code :Device Query

Website (Download page) :

Windows : http://developer.download.nvidia.com/compute/cuda/sdk/Projects/deviceQuery.zip
Linux : http://developer.download.nvidia.com/compute/cuda/sdk/Projects/deviceQuery.tar.gz

This program is compiled under linux ( Ubuntu 7.10, Nvdia 8800 GTX)

Program Execution :

extract the code on the desktop in Test directory

run the make file

root@fluorine8:~/Desktop/Test/NVIDIA_CUDA_SDK$ make

if you hit the "nvcc: command not found" Error

then add this paths using command line

export PATH=$PATH:/usr/local/cuda/bin

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib

run make once more

make[1]: Entering directory `/home/class/wasp01/Desktop/Test/NVIDIA_CUDA_SDK/common'

make[1]: Leaving directory `/home/class/wasp01/Desktop/Test/NVIDIA_CUDA_SDK/projects/deviceQuery'
Finished building all

This message means compilation went through properly


Now to run the program go to the bin/linux/release directory

root@fluorine8:~/Desktop/Test/NVIDIA_CUDA_SDK$ cd bin/linux/release/

check the deviceQuery file is in place

root@fluorine8:~/Desktop/Test/NVIDIA_CUDA_SDK/bin/linux/release$ ls
deviceQuery

run the file by ./deviceQuery

root@fluorine8:~/Desktop/Test/NVIDIA_CUDA_SDK/bin/linux/release$ ./deviceQuery

Test PASSED

Press ENTER to exit...

HURRAA.... through your self a pary... you are done with the first step in CUDA software compilation and software bench testing process.

Fell free to post the comments and queries...
