Ten Forces that Flattened the World

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 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
• Widely used open-source middleware• 1,000’s of user companies,
many mission-critical

Applying ACE+TAO in the DoD
• 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
ACE & TAO middleware has been transitioned to hundreds of DoD programs & projects, including
• 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 RemarksResearchers & developers of distributed real-time & embedded (DRE) systems face common challenges
R&D Synergies
Our open-source ACE+TAO middleware has had a major impact on addressing these challenges for research & production DRE systems
•e.g., connection management, service initialization, error handling, flow & congestion control, event demuxing, distribution, concurrency control, fault tolerance synchronization, scheduling, & persistence
