Code Network • IQ-ECho Approach: • Adaptive Applications on Programmable Platforms • ECho: High performance events: • Event-based peer-to-peer data communication infrastructure • QoS: Runtime adaptation via dynamic code generation and mirroring • Source-based filtering: meet required application QoS by disposition of application-specific code into remote sites and underlying platform • Mirroring: utilize redundancy to improve responsiveness • IQ-ECho: Integrated QoS management through dynamic quality attributes: • Adaptation of platform (protocols and middleware) and of applications (adaptation-awareness) Publications and Demos • Supercomputing 2000 • efficient binary message formats • Int. Parallel and Distrib. Processing Symposium (IPDPS) 2000 • active User Interfaces • High Performance Distributed Computing (HPDC) 2000 • ECho • Real-Time Applications and Systems (RTAS) 2001 • Quality Events • High Performance Distributed Computing (HPDC) 2001 • Mirroring, Filtering, XML • Supercomputing 2001 • Path-based Filtering) • Demo • Differential Filtering QoS: Source-based Filtering: Achieving Desired QoS via Dynamic Code Generation Source F( ) Sink F( ) Source Filter Function: 2500 { if ((data inside viewing area) and (data values inside useful ranges)) { return 1; /* submit into channel */ } return 0; /* suppress data */ } 2000 1500 1000 500 0 Active Sink Passive Sink
