Recovering from distributable thread failures in distributed real-time Java
We consider the problem of recovering from failures of distributable threads (“threads”) in distributed realtime systems that operate under run-time uncertainties including those on thread execution times, thread arrivals, and node failure occurrences. When a thread experiences a node failure, the result is broken thread having an orphan. Under a termination model, the orphans must be detected and aborted, and exceptions must be delivered to the farthest, contiguous surviving thread segment for resuming thread execution. Our application/scheduling model includes the proposed distributable thread programming model for the emerging Distributed Real-Time Specification for Java (DRTSJ), together with an exception handler model. Threads are subject to time/utility function (TUF) time constraints and an utility accrual (UA) optimality criterion. A key underpinning of the TUF/UA scheduling paradigm is the notion of “best-effort” where higher importance threads are always favored ove...
