Traditional loop-scheduling schemes are designed for homogeneous computing environments, and are probably not suitable for emerging heterogeneous PC clusters. this paper applies a two-phased method, named HPLS (Hybrid parallel Loop Scheduling), to heterogeneous PC-cluster environments. the key idea is to distribute most of the workload to each node according to its performance, which is modeled and estimated in advance. Experiments on our testbed PC-cluster showed that, in most cases, our method could reduce the execution time of application programs more than previous schemes could.
View-Oriented parallel Programming is based on distributed Shared Memory which is friendly and easy for programmers to use. It requires the programmer to divide shared data into views according to the memory access pa...

this paper is aims at heterogeneity between local three-dimensional body scanning database, presents a Sort of data sharing, publishing and retrieving system architecture and approach over heterogeneous three-dimensional body scanning data sets distributed over Internet. the system mainly involve three-dimensional body scanning and apparel domain ontology model, domain rule database, an intelligent and semantic query engine, query facts database, analysis tools, maintenance and interface components etc. We constructed our three-dimensional body scanning database system and produced a standard model in our sharing web,it system according its ontology model. the proposed system can effective overcome the structure ana semantic heterogeneity of local three-dimensional body scanning database.
In recent years, distributed 3D sights simulation based on internet is attracting more and more attention for its many practical application. Based on Web Service technology, we design and develop a distributed simula...
