Abstract
The research here addresses the problem of improving software safety
through hazard detection. The premise of our work is that hazard
situations can and do occur, and are often complex, involving multiple
sources. So there is a need for a mechanism to detect complex hazards
and react in a timely and meaningful way. This paper addresses such a
detection mechanism through Cnet, an on-line analysis tool that supports
the specification of complex multi-source hazards using a query-like
language, uses both synchronous and asynchronous checking approaches to
balance efficiency and expressiveness, accommodates dynamic applications
through dynamic constraint addition, and supports distributed and parallel
applications running in heterogeneous environments.
