Extensions for Multi-Platform Support XML Build System Wrapper • XML based build descriptions for multi-platform support • An automated GNU patch generation based on fixes to ETICS components, timestamped and stored for future patching. • Python based module, used as an interpreter for XML build descriptions, an intermediate patching system applied between checkout and builds, and table/report generation. Extra Utilities • Automated timestamped checkouts of ETICS configurations to be patched from the ETICS command-line interface. • Automatic RPM/deb to tarball generators in a form ready for integration into ETICS. • Python scripts used to create wiki tables showing differences between multiple build result files. Reporting • Automatic sync and storage of XML/HTML in a directory structure allowing automatic HTML table generation. • A Hypergraph generator using the ETICS XML results set

Build Results & Achievements • • • Building on Cent. OS 5. x/4. x (x 86/x 86_64), Debian 4. 0/5. 0 (x 86_64), Mac OS X 10. 5 (x 86), Play Station 3 (Power. PC), open. SUSE 11. 1 (x 86_64) Local builds are way ahead of CERN for Debian 5. 0 x 86_64/x 86 although all patches auto-generated with timestamps are applied locally and defined in CERN savannah bug tracking system. Debian 5. 0/4. 0 x 86_64 g. Lite-UI/WN and open. SUSE 11. 1 x 86_64 glite-WN are ready for test. g. Lite-WN without DM is running on PS 3 for local users drug screening software.

Conclusions • TCD has been effectively using this software for 3 -4 years now. • The software is much more well developed since presented in CGW’ 07. • The software is relatively easy to manage and provides a good framework for anyone using ETICS locally. • The patches generated at the local sites MUST be fed back by NGI’s to EGI. • Going forward, open source development/porting of grid middleware should be encouraged!
