1. Madagascar on a Playstation 3 William Burnett Friday Seminar December 4, 2009

2. Motivation Curiosity Playstation 3 (PS3) is an expensive game console but a cheap home computer Cell processor

3. Overview PS3 background and hardware Linux on a PS3 Madagascar on a PS3

4. Precedence of PS3 in Geophysics Bednar and Bednar, 2007, Playing around with a seismic Playstation cluster, SEG Expanded Abstracts –Panorama Technologies Software Raytracing FD Modeling 2-way RTM Modified FD modeling code ran ~10 times faster than similar array of AMD processors.

11. PS3 Game Operating System

12. Linux on a PS3

13. Most Linux distributions work I chose Yellow Dog Linux 6.1 (YDL) –Designed with PS3 in mind –No one has put Madagascar on Yellow Dog Linux yet (as far as I know)

14. Getting Yellow Dog Linux http://www.yellowdoglinux.com/ Download DVD ISO Image: –yellowdog-6.1-ppc-DVD_20090201_NEW_PS3.iso Burn ISO image to a DVD Download/print the installation guide: –http://www.yellowdoglinux.com/support/installation/ydl6.1_ps3_guide.pdf

15. YDL Installation: Materials Yellow Dog ISO image DVD YDL installation guide or another computer with internet access USB keyboard and mouse HDTV connected by 5-component or HDMI or a monitor connected by HDMI

16. YDL Installation: Procedure 1.) Insert YDL DVD into Playstation while the power is on. 2.) Reboot into “Other OS”

17. YDL Installation: Procedure

20. 3.) Choose resolution –480i –720p –1080i –1080p Command Line Installation (Still pretty easy.) Graphical Installation (Easy!!!)

21. YDL Installation: Procedure 4.) Follow installation guide through configuration* 5.) Install (Go do something else) 6.) Follow guide through first-boot *At “Package Selection”, choose all three types of computer use: home, media, and programming

22. YDL Installation: Done! Finish by configuring wireless and desktop fontsize/themes.

23. YDL Installation: Done! Finish by configuring wireless and desktop fontsize/themes.

24. Get Madagascar Get Subversion (SVN)* From command line: –svn co https://rsf.svn.sourceforge.net/svnroot/rsf/trunk RSFSRC Unpack (tar –xvf …) *May be included if you select programming packages during YDL installation

25. Install Madagascar Follow ahay.org walkthrough: –http://ahay.org/wiki/Installationhttp://ahay.org/wiki/Installation One problem encountered: –Software included with YDL 6.1 did not have libXaw-devel development tool. Needed for sfpen, xtpen, etc… (Data displays) Found power pc version online, installation completed

26. Madagascar on a PS3!

27. Conclusions Madagascar in Yellow Dog Linux? –Yes Madagascar on a PS3? –Yes Extra computational power? –Not really SPE use requires special programming Memory is very limited

28. Things to look at… SPE development kit from IBM with C compiler: spu-gcc Modified code for Cell processor –Not platform independent, but may be interesting News of future Cell processor development (doesn’t look promising…)

29. Thanks!
