HOWTO : nVidia CUDA Toolkit 4.0 on Ubuntu 11.04 Server

The CUDA Toolkit 4.0 is released on May 2011. If you have nVidia display card that have several CUDAs on it, you will interested in this tutorial. This time, I would like to show you how to install CUDA Toolkit 4.0 on Ubuntu 11.04 Server.



You will experience a more faster server after the installation of CUDA Toolkit 4.0.



This HOWTO does not require to install X.



Step 1 :



Add the CUDA 4.0 PPA.

sudo add-apt-repository ppa:aaron-haviland/cuda-4.0



Thanks for the developer of CUDA 4.0 PPA - Aaron Haviland of his contribution to make CUDA Toolkit to be installed easily.



Step 2 :



sudo apt-get update

sudo apt-get upgrade



64-bit :

sudo apt-get install nvidia-cuda-gdb nvidia-cuda-toolkit nvidia-compute-profiler libnpp4 nvidia-cuda-doc libcudart4 libcublas4 libcufft4 libcusparse4 libcurand4 nvidia-current nvidia-opencl-dev nvidia-current-dev nvidia-cuda-dev opencl-headers



32-bit :

sudo apt-get install nvidia-cuda-gdb nvidia-cuda-toolkit nvidia-compute-profiler lib32npp4 nvidia-cuda-doc lib32cudart4 lib32cublas4 lib32cufft4 lib32cusparse4 lib32curand4 nvidia-current nvidia-opencl-dev nvidia-current-dev nvidia-cuda-dev opencl-headers



Step 3 :



sudo nano /etc/init.d/nvidia_cuda



Append the following lines.



============= Copy from here ================

#!/bin/bash



PATH=/sbin:/bin:/usr/bin:$PATH



/sbin/modprobe nvidia



if [ "$?" -eq 0 ]; then



   # Count the number of NVIDIA controllers found.

   N3D=`/usr/bin/lspci | grep -i NVIDIA | grep "3D controller" | wc -l`

   NVGA=`/usr/bin/lspci | grep -i NVIDIA | grep "VGA compatible controller" | wc -l`



   N=`expr $N3D + $NVGA - 1`

   for i in `seq 0 $N`; do

      /bin/mknod -m 666 /dev/nvidia$i c 195 $i;

   done



   /bin/mknod -m 666 /dev/nvidiactl c 195 255



else

   exit 1

fi



=========== Copy to here =================



Step 4 :



sudo chmod +x /etc/init.d/nvidia_cuda

sudo update-rc.d nvidia_cuda defaults



Step 5 :



Reboot your system.



Remarks



I do not have nVidia display cards server in hand at the moment, I am not sure the captioned startup script working properly or not.



That's all! See you.
