On Message.Dependent Deadlocks in Multiprocessor/Multicomputer Systems
The existence of multiple message types and associated intermessage dependencies in multiprocessor/multicomputer systems may cause message-dependent deadlock in networks that are designed to be free of routing deadlock. In this paper, we characterize the frequency of message-dependent deadlocks using empirical methods. Results show that message-dependent deadlocks occur very infrequently under typical circumstances, thus rendering approaches based on avoiding them overly restrictive in the common case.
We model cross-market Bitcoin prices as long-memory processes and study dynamic interdependence in a fractionally cointegrated VAR framework. We find long-memory in both the individual markets and the system of markets depicting non-homogeneous informational inefficiency. Moreover, Bitcoin markets are found to be fractionally cointegrated, where uncertainty negatively impacts this type of cointegration relationship.
