Abstract :

  A computational grid is a hardware and software infrastructure.  Grid provides dependable, consistent and inexpensive access to high-end computational facilities. Globally distributed data and resources are scheduled to the tasks. Computational grids and Data grids are the 2 major types of the Grid environment. Processor and network bandwidth resource are shared under computational grids. Data Grid provides a scalable infrastructure for managing and storing data files. Scientific applications produce huge volume of data files. Mutual and economic resource sharing schemes are available in the grid environment.    GSPs are permanently connected with the Virtual Organizations under the static VO model.  Dynamic VOs are formed to execute a given task and once the task is completed they are dismantled. The life cycle of a VO can be divided into four phases. They are identification, formation, operation and dissolution. The possible partners and the VO’s objectives are identified in the initiation phase. The terms, goal and the duration of collaboration are finalized in the formation phase. The operation phase is involved to solve the specific task. In the dissolution phase the VO is dissolved after the completion of the tasks. The Merge-and-Split VO Formation Mechanism (MSVOF) allows the GSPs to make their own decisions to participate in VOs. The MSVOF algorithm constructs the VO with cost and deadline considerations. The selfish split rule is used to find the optimal VO in the VO structure. Branch-and-bound method is used for mapping of the tasks to each of the VOs that minimizes the cost of execution.    The MSVOF mechanism is enhanced to support trust and security for the GSPs. The system provides the security for resource information and data values. Fault tolerant resource scheduling model is integrated with the VO scheme. The VO construction process upgraded with communicational aspects.
