CREDO Overview

What is CREDO?

Modeling and analysis of evolutionary structures for distributed services

  • Aim: Compositional modeling and validation framework for

dynamically evolving software

  • Separation of concerns: computation, coordination, scheduling
  • Partners
  • Academic: CWI Amsterdam, U Oslo, U Kiel, TU Dresden,

UNU-IIST Macau, U Uppsala

  • Almende: ASK system – dynamically connecting people
  • Rikshospitalet, NCC: Biomedical sensor networks
  • Project duration: 3 years from Sep. 2006 (FP6, STREP)

CREDO Overview

Modeling

  • Creol
  • Executable OO modeling
  • Active objects, futures, support for reprogramming
  • Abstracts from internal scheduling
  • ADTs for internal state
  • Abstracts from environment/network properties
  • Coordination & scheduling
  • Reo: general coordination language
  • Network behavior: (mobile) channels with various properties
  • Application-specific schedulers for intra-object processes

CREDO Overview

Validation

  • Approach: Lightweight, not deductive techniques
  • Validation by automatable techniques
  • Simulation: Creol interpreter allows querying-driven simulation
  • Type-based analysis: both for concurrent objects and network
  • Testing: both for concurrent objects and network
  • Model checking: esp. for coordination/schedulers aspects

Talks today

  • M. Kyas: OO models and Heterogeneous Networks
  • B. Aichernig: Testing Concurrent Objects
  • S. Kl¨
