[CUDA] CUDA 學習筆記

1. 安裝
   http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#post-installation-actions
    
     一定要記得最後一步的
   

   export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}

   每次開機都要執行
   或者是直接修改
   
   The PATH variable needs to include your cuda /bin directory (by default it is /usr/local/cuda-6.5/bin)
   On Ubuntu you can edit the. bashrc file on your $HOME directory, adding the following;

   export PATH=/usr/local/cuda-6.5/bin:$PATH
   export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib64:$LD_LIBRARY_PATH

   If you are running a 32-bit Ubuntu version, then the paths are:

   export PATH=/usr/local/cuda-6.5/bin:$PATH
   export LD_LIBRARY_PATH=/usr/local/cuda-6.5/lib:$LD_LIBRARY_PATH

   After editing the bashrc file, source it (or simply restart the terminal):

   source ~/.bashrc

   Of course, if you have changed the default location of your CUDA directory you must change the PATHS accordingly.
   PLUS: there are another options to tell the system where to find a library, a program, etc. like using enviromental modules, specify the complete path to the libraries and programs manually are another options. There are many methods out there!

編譯方式有兩種

 1. 修改MAKEFILE       2. nvcc main.cu -o main

Instruction to run deciveQuery:
1. copy folder /usr/local/cuda/sample/1_Utilities/deviceQuery to directory with writting permission (such as home)
2. Modify Makefile
 line 147: modify to "INCLUDES := -I /usr/local/cuda/samples/common/inc"
 line 200,201,208: comment out
3. make, everything should be OK

To compile your code, please modify targets and dependency in line 195,198,204,207 of this Makefile.

If you have any problem, please contact TA.
