Search of a state transition system is traditionally how deadlock detection for concurrent programs has been accomplished. This paper examines an approach to deadlock detection that uses geometric semantics involving the topological notion of dihomotopy to partition the state-space into components; after that the reduced state-space is exhaustively searched. Prior work partitioned the state-space...
It is well recognized that debugging or testing a distributed system is a great challenge. FiLM is a runtime monitoring tool that can monitor the execution of distributed applications against LTL specifications on finite traces. Implemented within the online predicate checking infrastructure D3S, FiLM models the execution of distributed applications as a trace of consistent global snapshots with global...
