Impact
Schedule
Separation of synchronization concerns from functional code development will reduce development costs and improve quality
Seamless integration of complex synchronization policies with complex object-oriented designs and implementations
Developers will be able to leverage existing design knowledge via synchronization patterns embedded in tools
Automated checking of critical safety/liveness properties of woven concurrent code to reveal subtle defects, will complement traditional validation methods
Exploiting domain-specific aspect languages will dramatically reduce checking time making property verification tractable
