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

Installing PyOpenCl:
  • download PyOpenCL from PyOpenCL
  • make sure C++ compiler(g++), python, numpy, C++ boost library are installed
  • Tricky when execute python   --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"

    1. yes check for the newest version at AMD OpenCL site

  4. Does the CodeXL works for you? I can't use it.
