  3. Emphasis This Period… • Extensive interaction with Boeing with successive versions of Cadena leading to a public release. • tutorials and simple development guides • OEP recast to CCM designs with Java implementations • automated support for translating OEP scenarios to CCM • CCM OEP scenario repository • Intensive technology development on model-checking OEP scenarios leading to Bogor • a novel extensible model-checking tool for OO systems • Significant interaction with CIAO groups (Vanderbilt, Wash U) and Boeing on integrating Cadena with CIAO as well as moving forward on a number of important issues. PCES PI Meeting --- June 4, 2003

  4. OEP Delivery Plan (through 6/03) What we promised at the last meeting… PCES PI Meeting --- June 4, 2003

  5. Cadena • Five deliveries this Spring • 4 to Boeing (Feb, March, April, May) • 1 public binary release (June) • Features • Languages: CCM IDL, CAD, CPS • Editors: Textual, Forms-based • Analyses: Slicing, Dependences, Cycle-checks • Advice: Rate Assignment, Distribution • Visualizations: Structural, Analysis Results • System Generation: ORB integration PCES PI Meeting --- June 4, 2003

  6. Textual View PCES PI Meeting --- June 4, 2003

  7. Graphical View PCES PI Meeting --- June 4, 2003

  8. Spreadsheet View RT Attributes …distribution sites …rate group …ports for component type …port types …port connections PCES PI Meeting --- June 4, 2003

  9. Spreadsheet View Results of automatic rate group synthesis are fed back into spreadsheet PCES PI Meeting --- June 4, 2003

  10. Cadena ORB/EC Integration • Integration with FACET 1.5 (March, 2003) • Integration with OpenCCM 0.5 (May, 2003) • extended OpenCCM with event-channel implementation • Identified generic Cadena-ORB Interfaces • eases integration of CORBA-compliant event-channels • End-to-end Development Support • from Cadena CCM/CAD specifications … • to executable Java versions of OEP scenarios • Generates fully-compliant OEP XML config files • from OEP scenarios modeled as CCM/CAD PCES PI Meeting --- June 4, 2003

  11. Supporting Documentation • “Cadena tutorial” • delivered with releases • “Event-channel integration and QoS properties in Cadena/OpenCCM” • delivered to Boeing, WashU & Vanderbilt in support of generic ORB integration • “OEP to CCM via CAD” • delivered to Boeing, WashU & Vanderbilt in support of CIAO integration • KSU CCM Workshop (documents and slides) • 2-day workshop at KSU with WashU & Vanderbilt • http://www.cis.ksu.edu/santos/KSU-CCM-Workshop/ PCES PI Meeting --- June 4, 2003

  12. Technologies Developed (but not yet Delivered) • Languages: Behavioral, Property Specification • Cadena/BoldStroke Model Checking • CCM/CAD reverse-engineering from OEP XML • Reachable system mode generation • Advanced correlation facilities • Visualization zooming and layout support • Integration of • event-channel with QoS properties • Avionics Data Service (from Rockwell Collins) PCES PI Meeting --- June 4, 2003

  13. Model Checking BoldStroke Systems • Design-time validation technique • property = test goal • analysis run = set of test case runs • Domain-specific model checking • Customizable framework (Bogor) • BoldStroke-specific customization • Significant progress in scaling • Medium SP state-space:>13x106 7000, 8sec PCES PI Meeting --- June 4, 2003

  14. CCM/CAD Reverse Engineering • Lowers entry barrier to using Cadena • and other CCM-based tools on OEP • Rule based approach for reverse-engineering CCM from OEP scenarios • Based on discussions with Boeing • Tool-support under development • automatically convert OEP configuration XML to CCM IDL3, CAD, and CPS • Prototype seems effective on multiple OEP scenarios PCES PI Meeting --- June 4, 2003

  15. OEP Delivery Plan (6/03-12/03) PCES PI Meeting --- June 4, 2003

  16. OEP Experimentation (through 6/03) • Conducted a broad range of experiments • KSU : >40 experiments addressing 10 metrics • Boeing : 4 end-to-end experiments using various analysis capabilities • In all cases, significant improvement over baseline was shown for all metrics • Released experiment documentation • Delivered to Boeing (May-June, 2003) PCES PI Meeting --- June 4, 2003

  17. OEP Experimentation (6/03-12/03) • Integrated end-to-end experiments with CIAO • Current OEP support is adequate • Model checking • More OEP support is required • Property specification:test plans with explicit test goals for scenarios • Seeded errors:versions of scenarios with a variety of errors relative to test goals PCES PI Meeting --- June 4, 2003

  18. If we are successful … • Reductions in development time • Errors found early via pre-code analysis • Auto-generation of 80% of code-base • Hand-written code is small, simple and sequential • Improvements in quality • Explicit specifications of correctness properties • Designs checked against properties • Implementations generated to preserve properties • Improvements in performance • Generation of optimized middle-ware configurations • Platform independence • Eases retargeting of components and applications PCES PI Meeting --- June 4, 2003
