HOWTO nVidia CUDA 4 0 RC on Ubuntu 11 04 Server

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 4.0 RC on Ubuntu 11.04 Server.



You will experience a faster server after the installation of CUDA 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



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.



Thats all! See you.

Difference between FIX 4 2 vs FIX 4 4 in FIX connectivity

FIX 4.2 vs FIX 4.4

FIX protocol has evolved over time; it’s now more than a decade it’s started by Fidelity and Solomon Brothers. FIX connectivity is the most popular connectivity solution exists for trading whether its equities, futures, options or fixed income or even foreign exchange (FX).

Fedora 15 KDE How to upgrade to KDE 4 7

As a Fedora KDE user we sometimes have to wait that bit extra for KDE updates, nonetheless the efforts by the Fedora KDE team are much appreciated.

My Fedora 15 KDE 4.7 Desktop

I no longer use openSUSE, it has gone too sour for my liking and is surrounded by a lot of negativity. I am one of those who believe the negative energy of others can have a big impact on ones well being and since giving openSUSE the boot I have been feeling much better.

The how to...

The steps for upgrading KDE to version 4.7 was originally brought to my attention by browsing the Fedora Forum, see the post by ah7013. I have modified the steps slightly as those of us who installed Fedora KDE from the Live CD do not have wget installed.

Please note, KDE 4.7 is not in the Fedora 15 stable repository and the guide  will install KDE 4.7 from a repository created by Rex Dieter, a valued member of the Fedora KDE team.

Open a terminal and run the following commands,

cd /etc/yum.repos.d

su -c yum install wget

su -c wget http://repos.fedorapeople.org/repos/rdieter/kde47/fedora-kde47.repo

su -c yum update

Please reboot your system.

Enjoy KDE!
