Recently proposed Hole-Filler model is promising for transmitting and evaluating streamed XML fragments. However, by simply matching filler IDs with hole IDs, associating all the correlated fragments to complete the query path would result in blocking. Taking advantage of region-based coding scheme, this paper models the query expression into query tree and proposes a set of techniques to optim...

In traditional object-oriented languages, method calls are synchronous: The thread of control is passed from the caller to the callee, blocking the caller until the call is finished. This suits tightly coupled systems but leads to unnecessary delays in distributed environments, where objects are dispersed geographically. Another problem shared by thread-based object-oriented languages is that c...

Dynamically Controlled Routing (DCR) is a centralized, adaptive network traffic management system which significantly enhances network performance and survivability. In a DCR network, switches communicate with a network processor which computes routing recommendations for overflow traffic based on near real time network status and traffic volume information. A DCR network, when properly dimensi...

Multithreading as attractive in a large-scale parallel system since it allows split-phase memory operations and fast context switching between computations without blocking the processor. Performance of multithreaded archifectures depends significantly on the quality of multithreaded codes. In this paper, we describe the enhanced thread formation scheme to produce efficient sequential threads f...

FastFlow is a programming framework specifically targeting cache-coherent shared-memory multicores. It is implemented as a stack of C++ template libraries built on top of lock-free (and memory fence free) synchronization mechanisms. Its philosophy is to combine programmability with performance. In this paper a new FastFlow programming methodology aimed at supporting parallelization of existing ...
