Towards Resource Reliability Support for Grid Workflows

چکیده
Grid workflow can be defined as an organization of Grid Services into a well-defined flow of operations, and can be thought of as the composition of Grid Services over time on heterogeneous and distributed resources in a well-defined order to accomplish a specific goal. To the time-constrained workflow Scheduling in Grids, we present a scheduling algorithm in terms of the finite-state continuous-time Markov process by selecting a resource combination scheme which has the lowest expenditure under the certain credit level of the resource reliability on the critical path in the DAG-based workflow. The simulation shows the validity of theory analysis.

متن کاملAutonomic Workflow Management System for Grid Computing
As many of the large-scale scientific applications executed on Grids are expressed as complex scientific workflows, workflow management has emerged as one of the most important Grid services in past few years. Scientific workflows can be defined as the aggregation of Grid application services, which are executed on distributed Grid resources in a well defined order to satisfy the specific requi...
متن کاملUtilizing Heterogeneous Data Sources in Computational Grid Workflows
Besides computation intensive tasks, the Grid also facilitates sharing and processing very large databases and file systems that are distributed over multiple resources and administrative domains. Although accessing data in the Grid is supported by various lower level tools, end-users find it difficult to utilise these solutions directly. High level environments, such as Grid portal and workflo...
متن کاملNovel Approaches for Scheduling in D-Grid – Towards an interoperable Scheduling Framework
As the Grid is becoming the day-to-day infrastructure for e-Science and e-Business, support is required for more complex and demanding application scenarios in which not just a single resource is required, but a set of resources with certain dependencies. Such workflows complicate the management of resources, especially in cases where they are offered by several different resource providers, si...
متن کاملLOGOS: Enabling Local Resource Managers for the Efficient Support of Data-Intensive Workflows within Grid Sites
In this study we discuss how to enable grid sites for the support of data-intensive workflows. Usually, within grid sites, tasks and resources are administrated by local resource managers (LRMs). Many of LRMs have been designed for managing compute-intensive applications. Therefore, data-intensive workflow applications might not perform well on such environments due to the number and size of da...
