A wait-free NCAS library for parallel applications with timing constraints

Abstract

We introduce our major ideas of a wait-free, linearizable, and disjoint access parallel NCAS library, called rtNCAS. It focuses the construction of wait-free data structure operations (DSO) in real-time circumstances. rtNCAS is able to conditionally swap multiple independent words (NCAS) in an atomic manner. It allows us, furthermore, to implement arbitrary DSO by means of their sequential specification.
