The development in the technology of grid computing and Web Services has made it possible to integrate various computational resources to handle challenging scientific and engineering computations[NW03]. Combined with the technology of Web Services and the existing NetSolve[Don02][CD97], we present a new grid system for scientific computing. We analyze the system architecture, illustrated the advantages,...
A new way of combine the widely used PETSc math library and NetSolve (gird computing middleware) is explored in this paper. Using PDF file of NetSolve, applications using PETSc libraries can be called by NetSolve. However, the disadvantage of NetSolve Server causes the MPI’s programs can not make good use of the Server’s resource, which will lead to performance degradation of Server. A middle layer...
Cloud computing is the development of parallel computing, distributed computing and grid computing. It has been one of the most hot research topics. Now many corporations have involved in the cloud computing related techniques and many cloud computing platforms have been put forward. This is a favorable situation to study and application of cloud computing related techniques. Though interesting, there...
An agent is introduced into workflow management of PSE-Bio, and the agent composition model for workflow in Web service-based PSE is also proposed in this paper. In this model, workflow can cooperate with three kinds of autonomy agent which are interface agent, task agent and resource agent, so as to realize heterogeneous services integration and distributed task management based on intelligence and...
To utilize technology of various areas effectively and efficiently, a grid enabled problem solving environment for bioinformatics (PSE-Bio) is built. This paper describes the architecture of PSE-Bio and proposes the new layer, Agent bundle, based on classical architecture with three layers. As a service bundle, Agent provides common single mechanism to access grid services, by which portal services...
Data grids have become an important emerging platform for managing and processing high throughput distributed data today. Especially in the biology field, many research groups freely share their own experiment data and results, which obtained at the high experiment cost. This paper presents a data grid named BD-Grid to provide a data platform, which integrates the heterogeneous distributed biologic...
We investigate the migration of network-based PDE.Mart to the grid platform. The grid architecture of PDE.Mart is presented. Grid-based PDE.Mart is a service-oriented system, and is implemented based on Apache AXIS and Tomcat Web service server. Implementation issues are discussed in detail
