  3. Objectives ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010

  4. Objectives Objective 1Development of technologies to allow efficient and secure federation of resource sites Objective 2Development or integration of virtualization technologies in the job management middleware • Objective 3Modification of the job submission middleware and system management tools to run on IPv6 networks ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010 4

  5. Major Achievements ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010

  6. Achievement 1:Web services definition & implementation In service of Objective 1 (… to allow efficient federation of sites) • DJRA1.1 (Specification) • DJRA1.4 (Implementation) We developed a web service interface to Metronome • Allows straightforward remote access to Metronome, the underlying build and test framework • Covers access to all major Metronome functionality ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010 6

  7. Achievement 2:Virtualization In service of Objective 2 (… integration of virtualization technologies) • DJRA1.3 (Prototype) • DJRA1.5 (Integration) Three major scenarios explored: • Integration in the middleware • Done in Condor • Integration in the ETICS client • ETICS VMLoader done in collaboration with SA1 • Independent of the middleware implementation • Integration in the infrastructure • Amazon EWS connector done by SA2 ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010 7

  8. Achievement 3:IPv6 Compliance In service of Objective 3 (… modification … to run on IPv6 networks) • DJRA1.2 (Analysis) • DJRA1.6 (Compliance) We analyzed IPv6 compliance • As much as we have control over, ETICS is IPv6 compliant: Metronome, ETICS, etc… • There are some underlying dependencies for which we do not have control, and are not yet IPv6 compliant (MySQL , Condor) • These are very complex, large code bases, and it’s beyond the scope or ability of the ETICS 2 project to make them compliant • We informed EU Commission last autumn of this state of affairs, and it was considered acceptable 8

  9. Metrics and Statistics ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010

  10. Metrics and Statistics (1/2) All deliverables completed, DJRA 1.1-1.6. • 1.6 defines the partially completed state, as described earlier. Metric: IPv6 coverage • Hard to evaluate: lines of code? Component count? • ETICS: Compliant • Metronome: Compliant • Condor: Not compliant • MySQL database: Not compliant • Underlying tools: compliant • Wget, cvs, Subversion, etc… • 30% - 50% compliant ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010

  11. Metrics and Statistics (2/2) Metric: Requirement ratio • Requirements implemented over requirements collected • Two new requirements during ETICS 2: • Improve cross site submission: implemented • Job submission from Metronome to other batch systems: demonstrated with submission via Condor-G to Globus. Why Globus? • Mechanism (Condor-G) is applicable for wide set of systems • Easy to deploy at UW-Madison • Work in SA2 in ETICS 2 demonstrated submission to gLite—we wanted to show we could work with other systems as well • Ratio is 100% ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010

  12. Further work and conclusions ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010

  13. Lessons Learned A high-quality build and test environment is difficult to build, but an invaluable tool for developers Lesson learned: adding virtualization in a meaningful way is more work than it looks. • What is the right architecture to integrate them? • Who creates the VM? How? • Where do you store the VMs? • How do you get good performance from the VM? Lesson learned: IPv6 compliance is more than changing a few call sites ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010 13

  14. Conclusions All objectives accomplished IPv6 compliance has been completed to the full extent of the ETICS 2 scope Improvements to virtual machine integration will continue via improvements to Metronome and further integration with emerging virtualization tools ETICS 2 Final Review - Project Achievements - Brussels, 11 May 2010
