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-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

Applying ACE+TAO in the Do. D ACE & TAO middleware has been transitioned to hundreds of Do. D programs & projects, including • US Navy DDG 1000 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

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

Concluding Remarks R&D Synergies R&D Researchers & developers of distributed realtime & embedded (DRE) systems face common challenges • 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
