Install OpenCL and PyOpenCL in Ubuntu 10.04 LTS Lucid Lynx 64 bit

After playing with Scientific Linux 6 with OpenCL and PyOpenCL, I decided to bring it into my primary OS, and yes it is Ubuntu 10.04 LTS Lucid Lynx 64 bit.

Searching through the net, I found two ways to install OpenCL

• by using a packaged deb made by nou at AMD dev central forum -> Ubuntu package with ATI Stream SDK
• and by installing it manually using the AMD-APP-SDK-v2.4-lnx64.tgz

Because my previous experience in SL6 is worked, so i liked to doing so within my ubuntu.

Things that needed by my system for OpenCL(testing that it works by executing 'make all' in your $AMDAPPSDKROOT -> i put it on "/home/user/AMD-APP-SDK-v2.4-lnx64/", this will built samples application that included in samples folder)

• read the guide AMD_APP_SDK_Installation_Notes.pdf (it just extract and put a conf in /etc dir)
• install libglu1-mesa-dev (in my case the package(header files) that missing is only this, so might be different on your system!), this needed when build a OpenCL samples
• also add a AMDAPPSDK in your $PATH in .bashrc file like this

Below are some screenshoot to test sample applications under AMD-APP-SDK-v2.4-lnx64/samples/opencl/bin/x86_64/ directory if the installation of AMDAPPSDK and is working:
test using HelloCL

test using GlobalMemoryBandwidth

 

and notice if running an OpenCL program using all processor thread(because i didn't have a GPU capable for OpenCL

And now for PyOpenCL(made by Andreas Klöckner at http://mathema.tician.de/software/pyopencl )
To install correctly please enable the internet connectivity its needed to install required python dependency module.

In my system is need to install libboost1.40-all-dev, python-numpy and python-libxslt. (Both are available from ubuntu repository). Using command from terminal -> sudo apt-get install libboost1.40-all-dev python-numpy python-libxslt

Installing PyOpenCl:

• download PyOpenCL from PyOpenCL
• Notice when execute configure.py : python configure.py   --cl-inc-dir=$AMDAPPSDKROOT/include   --cl-lib-dir=$AMDAPPSDKROOT/lib/x86_64   --cl-libname=OpenCL
• then -> python setup.py build
• finnally -> sudo python setup.py install

test PyOpenCL using examples benchmark-all.py

BTW  I'm just noticed that python in ubuntu is faster than in Scientific Linux 6, and it same 64 bit, same laptop.

Install OpenCL and PyOpenCL in Scientific Linux 6 (RHEL 6, CEntOS 6)

My rig is 64 bit system with RedHat 6 based OS, but my fera not supported for OpenCL using VGA(3200), so it using SSE2 from L310 processor  :(

Note that my Scientific Linux 6 installed from a 64 bit LiveDVD version, so might be a different step if using LiveCD.

Installing AMD APP:

• download AMD APP SDK from AMD-APP-SDK-v2.4-lnx64.tgz
• extract and install following this AMD_APP_SDK_Installation_Notes.pdf

Test using a sample
$ ./HelloCL
HelloCL!
Getting Platform Information
Creating a context AMD platform
Getting device info
Loading and compiling CL source
Running CL program
Done
Passed!

Installing PyOpenCl:

• download PyOpenCL from PyOpenCL
• make sure C++ compiler(g++), python, numpy, C++ boost library are installed
• Tricky when execute configure.py: python configure.py   --cl-inc-dir=$HOME/AMD-APP-SDK-v2.4-lnx64/include   --cl-lib-dir=$HOME/AMD-APP-SDK-v2.4-lnx64/lib/x86_64   --cl-libname=OpenCL
• then just make -> su -c "make install"
