gLite 3.2.5-0 WN on the Play Station 3

Installation Guide

Yellow Dog Linux 6.2 Installation

• Follow the installation instructions described on http://www.yellowdoglinux.com/support/installation/
• We strongly suggest contrary to the documentation provided by Yellow Dog Linux, that you install a non-graphical 64-bit installation using the kboot setting: "install_ppc64_text" as described on Page 8 of the PS3 PDF install guide: http://www.yellowdoglinux.com/support/installation/ydl6.2_ps3_guide.pdf.

PS3 WN installation

Create a yum repository list for the WN software and torque client in /etc/yum.repos.d/yellowdog-wn.repo

[gi-gLite-WN]
name=yellowdog-$releasever - Grid-Ireland YellowDog 6.2 natively built gLite-WN
baseurl=http://grid.ie/distribution/glite/R3.2/glite-WN-3.2.5-0/yellowdog6/ppc32/RPMS.nowarranty/
gpgcheck=0

[gi-gLite-TORQUE-client]
name=yellowdog-$releasever - Grid-Ireland YellowDog 6.2 natively built gLite-TORQUE-client
baseurl=http://grid.ie/distribution/glite/R3.2/glite-TORQUE_client-3.2.5-0/yellowdog6/ppc32/RPMS.nowarranty/
gpgcheck=0

Create also a yum repository list for the LCG-CA in /etc/yum.repos.d/lcg-CA.repo

[CA]
name=CAs
baseurl=http://linuxsoft.cern.ch/LCG-CAs/current
gpgcheck=0

As root run:

yum update
yum install glite-WN glite-TORQUE_client
yum install lcg-CA

Yaim Configuration

     sed -i "s#/var/spool/pbs#/var/torque#" /opt/glite/yaim/functions/config_torque_client

Follow the Yaim configuration laid down in: YaimGuide400. Essentially one must provide a site-info.def so as to run:

      yaim -c -s site-info.def -n glite-WN  -n TORQUE_client

Differences to Production WNs

• The PS3 has no missing components (i.e, it contains dCache, LFC/DPM clients)
• The components in this distribution are in many cases newer than the components provided by the glite-WN 3.2.5-0 release on SL5 x86_64. However, because the distribution is a no warranty version, each component was built from the development branch, not the production branch. In some cases this resulted in versioning of the form 3.2.0-0 which will be misleading.

Testing of No Warranty PS3 WN

• The certification testsuite UIonWNtests.sh ran 100% successfully generating the following output PS3testResults

Caveats

Caveats in PS3 install

• installing the glite-WN on YDL 6.1 or 6.0 will most likely fail, because the version of java-1.5.0-gcj required to meet the Java requirements is not available in these older 6.0 and 6.1 OS distributions.
• The torque configuration provided with this distribution was built from an EPEL source RPM and therefore uses /var/torque for its mom_logs rather than /var/spool/pbs used on many SL5 systems.
• Do not enable the group "Java Development" at install time, since this will cause clashes with the glite-WN install. Run 'yum groupremove "Java Development"' as a quick workaround if mistakenly installed.
• The Yellow Dog Linux 6.2 PDF installation guide contains a typo in row 4 of the table on page 8. It should read "install_ppc64_text" not "install_ppc32_text".
• Support for the "Other OS" install option was removed by Sony in the PS3 Slim, announced in August 2009. This does not affect the old series, which is still able to boot other operating systems, even with the newest system software update http://en.wikipedia.org/wiki/Linux_on_the_PlayStation_3.
