Scientific Linux 6

Scientific Linux 6 based on Red Hat 6
Using 64 bit LiveDVD(around 2.2GB) download link SL-60-x86_64-2011-03-07-LiveDVD.iso
Installed to Acer Ferrari One(AMD Athlon X2 L310 1.2Ghz, 4 GB DDR2 RAM, vga ATI Radeon HD3200)

Some work todo:

• change hostname -> /etc/sysconfig/network and edit this line HOSTNAME="<hostname>"
• install ati proprietary driver from ati website, (made compiz works, but booting with default plymouth(ugly) verbose, 3d accel work)
• enabling other repo(note: many dependency problem ocurred if enabling many repo at the same time), see below

install atrpms-repo-6-4.el6.x86_64.rpm
wiki EPEL repo for redhat, install epel-release-6-5.noarch.rpm
download latest rpmforge-release from http://packages.sw.be/rpmforge-release/


Test result for the moment:
worked well

• webcam
• power management -> sleep, hibernate
• audio
• display with 3d accel, compiz
• vga port to external display(better than in ubuntu lucid 64 bit that hang when the monitor res are not meet the conf)
• bluetooth
• wifi
• lan

worked but uhmm:

• firefox weird, lag when scrollng page, so just install chrome(work well, no lag) from google directly http://www.google.com/chrome/ , use 'rpm -Uvh google-chrome-stable_current_x86_64.rpm' and  need to install redhat-lsb pkg first
• battery performance not as good as in ubuntu lucid lynx 64 bit  now battery fine after install ati proprietary driver

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"
