With graphics card becoming programmable, the sheer computing power at user disposable is just amazing. I assembled a PC a few days ago and decided to install Ubuntu 10.04 as I didn’t want to spend money on OS. I am a newbie to linux and CUDA and I decided to share my experiences with everyone and simplify the learning curve for most of us.<o:p></o:p></span></div><div class="MsoNormal"><br />
</div><div class="MsoNormal"><span style="color: black; font-family: Verdana; font-size: 10pt;">As my Laptop did not have hardware support for CUDA, I assembled a PC with Nvidia graphics card. The details are as follows.<o:p></o:p></span></div><div class="MsoNormal"><br />

Though NVIDIA has a <b><a href="http://developer.download.nvidia.com/compute/cuda/3_2/docs/Getting_Started_Linux.pdf">Linux getting started guide</a></b>, it is generic in nature with OS specific details missing. After reading a couple of blogs, technical resources, and websites, the set of instructions needed to successfully install CUDA on a PC running ubuntu should be as follows.<o:p></o:p></span></div><div class="MsoNormal"><br />
</div><div class="MsoNormal" style="margin-left: 39.75pt; mso-list: l0 level1 lfo1; tab-stops: list 39.75pt; text-indent: -21.75pt;"><span style="color: black; font-family: Verdana; font-size: 10pt;">1.)<span style="font: normal normal normal 7pt/normal 'Times New Roman';"> </span></span><span style="color: black; font-family: Verdana; font-size: 10pt;">This process assumes that ubuntu has been freshly installed on the computer.<o:p></o:p></span></div><div class="MsoNormal" style="margin-left: 39.75pt; mso-list: l0 level1 lfo1; tab-stops: list 39.75pt; text-indent: -21.75pt;"><span style="color: black; font-family: Verdana; font-size: 10pt;">2.)<span style="font: normal normal normal 7pt/normal 'Times New Roman';"> </span></span><span style="color: black; font-family: Verdana; font-size: 10pt;">Download the graphics card driver, CUDA toolkit and SDK samples and save it on the computer.<o:p></o:p></span></div><div class="MsoNormal" style="margin-left: .25in;"><br />
</div><span style="color: black; font-family: Verdana; font-size: 10pt;">We first remove any Nvidia drivers installed on the system with the following command.<br />
<b style="mso-bidi-font-weight: normal;">sudo apt-get purge nvidia-*</b><br />
<br />
3) For each of installation and avoiding conflicts, we make a file in following location - "<b style="mso-bidi-font-weight: normal;">/etc/modprobe.d/nvidia-graphics-drivers.conf</b>" and insert the following lines<span class="apple-converted-space"> </span><br />
<br />
<b style="mso-bidi-font-weight: normal;">blacklist vga16fb<br />
blacklist nouveau<br />
blacklist lbm-nouveau<br />
blacklist nvidia-173<br />
blacklist nvidia-96<br />
blacklist nvidia-current<br />

<span class="Apple-style-span" style="font-family: Verdana; font-size: small;"><span class="Apple-style-span" style="font-size: 13px;"><br />
</span></span><br />
<span class="Apple-style-span" style="font-family: Verdana; font-size: small;"><span class="Apple-style-span" style="font-size: 13px;">4) After this step, follow the procedure as documented in the </span></span><span class="Apple-style-span" style="font-family: Verdana; font-size: 13px;"><b><a href="http://developer.download.nvidia.com/compute/cuda/3_2/docs/Getting_Started_Linux.pdf">Linux getting started guide </a></b>available from Nvidia</span><br />
<span class="Apple-style-span" style="font-family: Verdana; font-size: 13px;"><br />
</span><br />
<span class="Apple-style-span" style="font-family: Verdana; font-size: 13px;">5) After using the Make command in SDK, I noticed that libraries like XLi and XMu were missing. Install the -dev version of these libraries and issue Make command again. That will solve the issue. </span>Acceleronehttp://www.blogger.com/profile/04517359277510858526noreply@blogger.com0
