In this report, we examine the workflow management process from a scheduling perspective. Recognizing that effective workflow management requires an ability to efficiently allocate limited resources to tasks over time, we concentrate on characterizing this domain as a continuous distributed scheduling problem and on understanding the requirements and opportunities for providing workflow schedul...

This chapter describes a study on workflow scheduling with fault tolerance. It starts with an understanding on workflow scheduling and fault tolerance technologies independently. Next, the chapter surveys the related works on the combination field of workflow scheduling and fault tolerance technologies. Generally, these works are classified into six categories corresponding to the six fault tol...

Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of distributed computing resources. Workflow scheduling is one of the key issues in the management of workflow execution. The scheduling process maps and manages the execution of the inter-dependent tasks on the distributed resources. Scheduling of workflows is a challenging task especially when many w...

Inspired from the robust control principle, a robust scheduling method is proposed to solve uncertain scheduling problems. The uncertain scheduling problem is modeled by a set of workflow simulation models, and then a scheduling scheme (solution) is evaluated by the results of workflow simulations that are executed by using the workflow models in the set. A variable neighborhood immune algorith...

Due to the complexity of scientific processes, compute and data intensive scientific workflows are often required to be executed in a distributed high-end computing environment, such as the Cloud. Most existing workflow scheduling algorithms only consider a computing environment in which the number of compute resources is bounded. Resources assigned to a workflow cannot be automatically determi...

Cloud Computing is the technology that provides on demand services and resources like storage space, networks, programming language execution environment on the top of Internet using pay as you go model. The concept of Cloud Computing emerging as a latest model of service provisioning in distributed system encourage researchers to investigate its advantages and drawbacks in executing scientific...

Workflow scheduling is an important part of cloud computing and based on different criteria it decides cost, execution time, and performances. A cloud workflow system is a platform service facilitating automation of distributed applications based on new cloud infrastructure. An aspect which differentiates cloud workflow system from others is market-oriented business model, an innovation which c...

The Grid Workflow scheduling is considered an important issue in Workflow management. Workflow scheduling is a process of assigning workflow tasks to suitable computational resources. Workflow scheduling significantly affects the performance and the execution time of the workflow. A Workflow scheduling approach falls in one of three categories: static, dynamic or adaptive. Grid environment is a...

Grid computing is becoming a mainstream technology for large-scale distributed resource sharing and system integration. Workflow management is emerging as one of the most important grid services. In this work, a workflow management system for grid computing, called GridFlow, is presented, including a user portal and services of both global grid workflow management and local grid sub-workflow sc...
