Installing and configuring ATI video card drivers
In this, we'll go into the details for installing and configuring
the ATI video card driver, followed by the AMD Accelerated Parallel
Processing (APP) SDK, CAL++, and OpenCL. Taking advantage of the ATI Stream
Technology, we can run computationally-intensive tasks, typically running on
the CPU, more quickly and efficiently. For more detailed information regarding
the ATI Stream technology, visit www.amd.com/stream.
The following
requirements need to be fulfilled:
·
A connection to the Internet is required to
complete this recipe
·
The preparation of the kernel headers is
needed before starting this task, which is explained in the Preparing kernel
headers recipe at the beginning of this chapter
How to do it...
Let's begin installing
and configuring the ATI drivers:
1. Download the ATI display driver required
for our system:
cd /tmp/
2. Start the
installation by typing the following command:
sh
amd-driver-installer-12-1-x86.x86_64.run
3. When the setup completes, reboot your system for the changes to
take effect and to prevent system instability.
4. Install the
dependencies needed for further steps:
apt-get install
libroot-python-dev libboost-python-dev libboost1.40-all-dev cmake
5. Download and untar
the AMD APP SDK according to your CPU architecture:
wget
http://developer.amd.com/Downloads/AMD-APP-SDK-v2.6- lnx64.tgz
mkdir AMD-APP-SDK-v2.6-lnx64
tar zxvf
AMD-APP-SDK-v2.6-lnx64.tgz –C /tmp/AMD-APP-SDK-v2.6- lnx64
cd AMD-APP-SDK-v2.6-lnx64
6. Install AMD APP SDK
by issuing the following command:
sh Install-AMD-APP.sh
7. Set the ATI Stream
paths into the .bashrc file:
echo export
ATISTREAMSDKROOT=/opt/AMDAPP/ >> ~/.bashrc
source ~/.bashrc
8. Download and
compile CAL++:
cd /tmp/
svn co
https://calpp.svn.sourceforge.net/svnroot/calpp calpp
cd calpp/trunk
cmake
make
make install
9. Download and
compile Pyrit:
cd /tmp/
svn co
http://pyrit.googlecode.com/svn/trunk/ pyrit_src
cd pyrit_src/pyrit
python setup.py build
python setup.py install
10. Build and install
OpenCL:
cd /tmp/pyrit_src/cpyrit_opencl
python setup.py build
python
setup.py install
11. Make a few changes
to the cpyrit_calpp setup:
cd /tmp/pyrit_source/cpyrit_calpp
vi setup.py
Replace the following
line:
VERSION = '0.4.0-dev'
With:
VERSION = '0.4.1-dev'
And also the following
line:
CALPP_INC_DIRS.append(os.path.join(CALPP_INC_DIR,
'include'))
With:
CALPP_INC_DIRS.append(os.path.join(CALPP_INC_DIR,
'include/CAL'))
12. Finally, add the
ATI GPU module to Pyrit:
python setup.py build
python
setup.py install
