Memory trace analysis is an important technology for architecture research, system software (i.e., OS, compiler) optimization, and application performance improvements. Many approaches have been used to track memory trace, such as simulation, binary instrumentation and hardware snooping. However, they usually have limitations of time, accuracy and capacity.(More)
The information content (IC) of concepts is a fundamental dimension in semantic similarity calculation. The IC of a concept is able to provide an evaluation of its degree of semantic generality and concreteness, which is great important semantic evidence modeled in the ontology. A proper quantification of IC requires an accurate evaluation of the structural(More)
Due to complex abstractions implemented over shared data structures protected by locks, conventional symmetric multithreaded operating system kernel such as Linux is hard to achieve high scalability on the emerging multi-core architectures, which integrate more and more cores on a single die. This paper presents GenerOS - a general asymmetric operating(More)
