The objective of the work is to propose a resource discovery model for distributed resources using grid brokering and dispute solving techniques in a grid environment. The synchronization between local and external schedulers and the effective utilization of the available resources can be achieved by dispute solving with periodical resource auditing processes by an agent technique. The discovery of...
Collaborative research has facilitated the development of distributed systems that provide users nontrivial access to geographically dispersed resources that are administered in multiple computer domains. The term grid computing is popularly used to refer to such distributed systems. Scientific simulations have traditionally been the primary benefactor of grid computing. The application of this technology...
Today, due to exciting developments in advanced computing techniques and technologies, many scientists can now make use of dedicated high speed networks and high performance computing. This so-called `e-Science' in enabling scientist across many fields to work together in global virtual research communities. What do these advancements mean for modeling and simulation? This advanced tutorial instigates...
In recent years, the research to the Grid economy has become a hot spot with the development of Grid technology. Some models and middleware have been proposed to improve the application of Grid economy. One remarkable result of these is the Grid Architecture for Computational Economy (GRACE) which contains the functionality of resource discovery, resource trade and resource allocation. However, in...
Recently, both networking and high-performance computing technologies have dramatically advanced. As a result, scientists can access large-scale data captured by scientific measurement devices with ease. Also, recent high-performance computing technologies such as the Grid and cloud computing have allowed scientists to use huge computational power harnessed on the Internet for their analysis of scientific...
We developed GridMACS, a grid-enabled web portal with the aim of providing GUI for GROMACS and running a molecular dynamics simulation in a grid environment. The portal is developed according to the basic grid system architecture by integrating the main grid layers such as the Gridsphere Portal Framework, Vine Toolkit (grid service) and Globus Toolkit (grid middleware). The integration with the computing...
The concept of topology-aware grid applications is derived from parallelized computational models of complex systems that are executed on heterogeneous resources, either because they require specialized hardware for certain calculations, or because their parallelization is flexible enough to exploit such resources. Here we describe two such applications, a multi-body simulation of stellar evolution,...
In the last decade, life science applications have become more and more integrated into e-Science environments, hence they are typically very demanding, both in terms of computational capabilities and data capacities. Especially the access to life science applications, embedded in such environments via Grid clients still constitutes a major hurdle for scientists that do not have an IT background....
In recent years, the study of the grid economy is becoming a new hot spot with the grid technology development. Lots of models and middleware have been proposed by scholars to improve the application of grid economy. In our previous research work we have proposed the resource pricing fluctuation module (RPFM) as a part of grid architecture for computational economy (GRACE). However, as nodes in the...
With the fast growth of grid service demands, an efficient resource management mechanism is required. Business-oriented algorithms were shown to be adequate to resolve such a problem. Business models mainly consider the problem of computing, storage and network resources virtualization. This paper investigates the problem of resource allocation under flexible traffic in market-oriented grids. We consider...
It is widely believed that future applications within the scientific and business communities would not be developed from scratch but assembled on the fly by reusing existing atomic services available in a grid ecosystem. This is premised on the fact that both domains have adopted the Service Oriented Computing (SOC) paradigm for developing its applications. However, providing key support components...
The usage of economics in grid systems designs has been very popular recently and a large number of system designers have attempted to use economic concepts to engineer the grid market mechanism that would enable an efficient allocation of resources. However, only few of these designs have been actually implemented and, in fact, very few, if any, have been successfully adopted by end users. The argument...
Healthcare data and medical information need to be seamlessly accessible and available at all times to the various healthcare stakeholders. Inability to share, integrate and access critical healthcare information is a challenge for the healthcare IT. Moreover, semantic interoperability of health-related heterogeneous data sources is a challenging issue and healthGrids are expected to address this...
This paper has a discussion and research on resource trading techniques and methods for manufacturing grid (MG). It firstly introduces the economics roles of manufacturing gird. Then it analyses the relationship between different economics roles. And based on the framework of MG resource management system, upon the price-based economic theory and the game theory-based economic theory paper puts forward...
This paper is presented based on paper and recent fruits gained by authors. The research background of a service oriented infrastructure for networkitized M&S, namely simulation grid, is firstly concisely introduced, then combined with authors' recent research on virtualization technology being applied to simulation grid, the phased research achievements of simulation grid are introduced in detail,...
Many mobile computing models try to solve many issues related to the mobile computing such as: mobile movement, data synchronization, embedded databases, data privacy and confidentiality, P2P dissemination models, middleware adaptability, and mobile transactions. In this paper we will focus on the last area which is the mobile transactions and a new model (The diagonal allocation grid and fixed timeout...
This is an introduction to the proceedings of the MWS 2007 workshop held at EDOC 2007. It first explains the motivation for and background of the workshop. Then, it contains a short description of the keynote, each long and short peer-reviewed paper, and the discussion session "impact of various execution environments on middleware for web services". After the closing statements, MWS 2007...
In order to accomplish high performance on grid workflow, grid resource management system needs a smart and swift resource allocation middleware. In this paper, we study the economy driven resource allocation problem based on market model of grid resource management architectures. We model the problem as the multiple choice knapsack problem (MCKP) and design the resource allocation optimization algorithm...
