Tesla 1U GPU Computing System Installation

Mounting the Tesla System in a Rack

Plan your rack configuration to ensure you have the proper cables to
reach from the Tesla system to your host system. The Tesla system
ships with 0.5-meter cables by default. An optional 2-meter cable is
available.

The Tesla system also ships with rails to fit a 4-post 19-inch EIA rack
as the default configuration.

If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than
room ambient temperature. Therefore, consideration should be given
to installing the equipment in an environment compatible with the
manufacturer’s maximum rated ambient temperature (Tmra). The
maximum operating ambient temperature is 35 ºC.

1 Remove one of the rails from the packing box.
2 Remove the mounting screws attached to either end of the rail.

Set aside as you will need these to secure the rail to the rack at the
end of the steps. Remove any existing graphics card (if there is one).
Save hardware (such as screws and brackets) to use when installing
the NVIDIA graphics card.

DRIVER INSTALLATION

DRIVER INSTALL ATION

This section contains the instructions to install
the software drivers within a Linux environment.

In addition to the NVIDIA drivers located on the
Installation CD included with your computing
board, the drivers can be downloaded from the
NVIDIA web site at www.nvidia.com.

The driver follows a unified architecture model in
which a single driver set is used for all supported
NVIDIA GPUs. Your previous NVIDIA unified
driver may not support your Tesla board. In that
case, you will need to install the drivers from the
CD or download from www.nvidia.com.

Driver Installation

Before you begin the installation, you should exit the X server and
close all OpenGL applications (it is possible that some OpenGL
applications persist even after the X server has stopped). You should
also set the default run level on your system such that it will boot to
a VGA console and not directly to X. Doing so will make it easier to
recover if there is a problem during the installation process.

Note: Refer to readme.txt located at /usr/share/doc/NVIDIA_
GLX-1.0/README.txt for more detailed information regarding
the linux driver installation.

DRIVER INSTALL ATION



1 Download the 32-bit or 64-bit Linux driver (the driver will have a

name similar to “NVIDIA-Linux-x86-100.14.11-pkg1. run” or
“NVIDIA-Linux-x86_64-100.14.11-pkg2.run”).

2 Change to the directory containing the downloaded file.
3 Run as root the NVIDIA-Linux*.run file downloaded in Step 1. As the

root user you can run the following executables:

In the cd.download_directory, choose either NVIDIA-Linux-x86-

100.14.11-pkg1.run or NVIDIA-Linux-x86_64-100.14.11-pkg2.run.
The NVIDIA-Linux*.run file is a self-extracting archive. When
executed, it extracts the content of the archive and runs the contained
nvidia installer utility, which provides an interactive interface to walk
you through the installation. nvidia-installer will also install itself to /
usr/bin/nvidia-installer, which may be used at some later time to
uninstall drivers, auto download updated drivers, etc.

4 Select Accept to accept the License Agreement.
5 Select Yes if a warning window displays indicating that there are

drivers already installed. Selecting Yes tells the installation process
to overwrite the previously installed drivers.

6 Select Yes when the Kernel Interface window displays. When the

installer runs, it will check for a precompiled kernel interface. If it
does not find one, it will attempt to locate an interface on the NVIDIA
ftp site and then download it.

DRIVER INSTALL ATION



7 Select OK to compile a kernel interface. If a kernel interface cannot

be downloaded, either because the FTP site cannot be reached or
because one is not provided, the installer will check your system for
the required kernel sources and compile the interface for you. You
must have the source code for your kernel installed for compilation
to work. On most systems this means that you will need to locate
and install the correct kernel source, kernel headers or kernel
development package.

Linking of the kernel interface (in the case that the interface
downloaded or compiled at installation) required you to have a linker
installed on your system. The linker, usually /usr/bin/ld is part of the
binutils package. If a precompiled kernel interface is not found, you
must install a linker prior to installing the NVIDIA driver.

8 Run the nvidia-xconfig utility. nvidia-xconfig will find the X configuration

file and modify it to use the NVIDIA X driver. If you have an NVIDIA
device that is graphics output capable, you can answer Yes when
the installer asks if it should run it. If you have no device capable of
displaying graphics output, answer No. If you need to reconfigure
your X server later, you can run nvidia-xconfig again from a terminal.
nvidia-xconfig will make a backup copy of your configuration file
before modifying it.

9 Installation is now complete.

Note: The X server must be restarted for configuration
file changes to take effect. More information about nvidia­xconfig can be found in the nvidia-xconfig manual page by

running: %man.nvidia.config.
