Scientific Workflow Composition in Heterogeneous Environments

Scientific workflows have become visible as a new method for scientists to develop and design complex and distributed scientific processes to enable and accelerate many scientific discoveries. Workflows are widely used in business for a long time. However, scientific workflows are emerging as an important technology for solving complex scientific problems and thereby contributing to scientific development. The advantages of high-performance grid-based computing for scientific workflows, and the problems noted with existing scientific workflow management software, provide the rationale for the development of new workflow processes for efficient use of heterogeneous scientific workflows system and utilizing grid computing. The main contributions of this paper are: 1) to propose a scientific workflow system to design, develop, and execute scientific workflows from heterogeneous scientific workflows; 2) to propose a scheduling technique for parallel executing of heterogeneous scientific workflows; and 3) to present a GENOEMFLOW based scientific workflow application to showcase the application of our system.
