With the increasing complexity of the Grid based application workflows, the workflow design process is also getting more and more complex. Many workflow design tools provide mechanism to ease the workflow design process and to make the life easier for a workflow designer. In this paper, we present a provenance based workflow design suggestion system for quick and easy creation of the error-free workflows...
Workflow execution time predictions for Grid infrastructures is of critical importance for optimized workflow executions, advance reservations of resources, and overhead analysis. Predicting workflow execution time is complex due to multeity of workflow structures, involvement of several Grid resources in workflow execution, complex dependencies of workflow activities and dynamic behavior of the Grid...
Grid schedulers require individual activity performance predictions to map workflow activities on different Grid sites. The effectiveness of the scheduling systems is hampered by inaccurate predictions due to the inability of existing predictors to effectively model the dynamic and heterogeneous nature of Grid resources, or the wide range of problem sizes and runtime arguments. To address this deficiency,...
Existing knowledge based grid workflow languages and composition tools require sophisticated expertise of domain scientists in order to automate the process of managing workflows and its components (activities). So far semantic workflow specification and management has not been addressed from a general and integrated perspective. This paper presents a novel domain oriented approach which features...
On-demand synthesis of grid activities can play a significant role in automatic workflow composition and in improving quality of the grid resource provisioning. However, in the grid, synthesis of activities has been largely ignored due to the limited expressiveness of the representation of activity capabilities and the lack of adapted resource management means to take advantage of such activity synthesis...
Workflows have emerged as a paradigm for representing and managing complex distributed computations and are used to accelerate the pace of scientific progress. A recent National Science Foundation workshop brought together domain, computer, and social scientists to discuss requirements of future scientific applications and the challenges they present to current workflow technologies.
Summary form only given. While grid infrastructures can provide massive compute and data storage power, it is still an art to effectively harness the power of grid computing. Current application development for grid commonly requires the programmer to deal with many low level and complex details such as selecting software components on specific grid computers, mapping applications onto the grid, explicitly...
