Madagascar on a Playstation 3

William Burnett

Friday Seminar

December 4, 2009


Motivation

  • Curiosity

  • Playstation 3 (PS3) is an expensive game console but a cheap home computer

  • Cell processor


Overview

  • PS3 background and hardware

  • Linux on a PS3

  • Madagascar on a PS3


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.

PS3 Game Operating System


Linux on a PS3


Linux on a PS3

  • 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)


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


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


YDL Installation: Procedure

  • 1.) Insert YDL DVD into Playstation while the power is on.

  • 2.) Reboot into “Other OS”


YDL Installation: Procedure

YDL Installation: Procedure


YDL Installation: Procedure

  • 3.) Choose resolution

    • 480i

    • 720p

    • 1080i

    • 1080p

Command Line Installation

(Still pretty easy.)

Graphical Installation

(Easy!!!)


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


YDL Installation: Done!

  • Finish by configuring wireless and desktop fontsize/themes.


YDL Installation: Done!

  • Finish by configuring wireless and desktop fontsize/themes.


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


Install Madagascar

  • Follow ahay.org walkthrough:

    • http://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


Madagascar on a PS3!


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


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…)


Thanks!
