PDF-WaitFree Synchronization MAURICE HERLIHY Digital Equipment Corporation Auaztfree implementation

The problem ofconstructinga waitfree implementation of one data object from another lies at the heart of much recent work in concurrent algorithms concurrent data structures and multiprocessor architectures First we introduce simple and general tech. This property is strong enough to avoid the problems associ ated with locks but it is weaker than previous nonblocking propertiesspeci64257cally lockfreedom and waitfreedom allowing greater 64258exibility in the design of ef64257cient imple mentatio We have no digital cable boxes that will work on digital cable tv No digital cable box is available Digital cable descrambler and digital cable box will be available someday At this time no digital cable tv box is available Look for digital cable de HERLIHY and JEANNETTE M WING Carnegie Mellon University A concurrent object is a data object shared by concurrent processes Linearizability is a correctness condition for concurrent objects that exploits the semantics of abstract data types It permi 26. th. .

Replication enhances tolerance to failure. Performance can be improved in different ways. Placing replicas in the proximity of the process using them. Replicating servers and subsequently dividing the work among them.
