For service-based applications which are composed of multiple independent third-parties, continuous monitoring is required to assure that runtime behavior of the systems complies with specified properties. However, most existing work only detects the violation while not consider how to enforce the properties so that the constraint can not be violated at runtime. To address this limitation, this paper...
While improving the performance, nonblocking communication is prone to synchronization errors between MPI applications and the underlying MPI libraries. Such synchronization error occurs in the following way. After initiating nonblocking communication and performing overlapped computation, the MPI application reuses the message buffer before the MPI library completes the use of the same buffer, which...
Runtime monitoring of Web service compositions has been widely acknowledged as a significant approach to understand and guarantee the quality of services. However, existing runtime monitoring solutions consider only the constraints on the sequence of messages exchanged between partner services and ignore the actual data contents inside the messages. As a result, it is difficult to monitor some dynamic...
Runtime monitoring of Web service compositions with WS-BPEL has been widely acknowledged as a significant approach to understand and guarantee the quality of services. However, most existing monitoring technologies only track patterns related to the execution of an individual process. As a result, the possible inconsistency failure caused by implicit interactions among concurrent process instances...
