DiRPOMS: Automatic checker of distributed realizability of POMSets

Abstract

DiRPOMS permits to verify if the specification of a distributed system can be faithfully realised via distributed agents that communicate using asynchronous message passing. A distinguishing feature of DiRPOMS is the usage of set of pomsets to specify the distributed system. This provides two benefits: syntax obliviousness and efficiency. By defining the semantics of a coordination language in term of pomsets, it is possible to use DiRPOMS for several coordination models. Also, DiRPOMS can analyze pomsets extracted by system logs, when the coordination model is unknown, and therefore can support coordination mining activities. Finally, by using sets of pomsets in place of flat languages, DiRPOMS can reduce exponential blows of analysis that is typical in case of multiple threads due to interleaving.
