2. Ten Forces that Flattened the World • 11/9/89 • 8/9/95 • Work Flow Software • Open-Sourcing • Outsourcing • Offshoring • Supply-Chaining • Insourcing • In-forming • The Steroids http://en.wikipedia.org/wiki/The_World_is_Flat

3. Open-Sourcing – Self-Organizing Collaborative Communities • Open-source is a scalable, cost effective, & reliable software process since: • Validation scales, development doesn’t • “End-to-end argument” applies to software • i.e., More resources at “periphery” than in “core”

4. Open-Sourcing – Self-Organizing Collaborative Communities • Open-source is a scalable, cost effective, & reliable software process since: • Validation scales, development doesn’t • “End-to-end argument” applies to software • i.e., More resources at “periphery” than in “core” • Open-source enables other flatteners • Lowers barriers to entry • Leverages global software talent • Accelerates technology transfer Open-source is essential for computing R&D visibility & impact

13. Applying ACE+TAO in the DoD ACE & TAO middleware has been transitioned to hundreds of DoD programs & projects, including • US Navy DDG1000 program with Raytheon, LMCO, & DARPA • US Air Force in collaboration with Boeing • Joint forces with JTRS SCA in collaboration with BAE Systems • JTT with US Army & Raytheon • USS Ronald Reagan aircraft carrier advanced tactical displays system • DMSO HLA/RTI & TENA with SAIC

14. Applying ACE+TAO to Mission- & Life-Critical Embedded Systems • Siemens hot rolling mills • The Weather Channel • GE & Phillips electronic medical imaging systems • Krones Beer Bottling Equipment

15. R&D Concluding Remarks Researchers & developers of distributed real-time & embedded (DRE) systems face common challenges R&D Synergies • e.g.,connection management, service initialization, error handling, flow & congestion control, event demuxing, distribution, concurrency control, fault tolerance synchronization, scheduling, & persistence Our open-source ACE+TAO middleware has had a major impact on addressing these challenges for research & production DRE systems
