Supporting an interactive scientific workflow in aerodynamics analysis over e-Science environment

摘要

Due to diverse characteristics of application domains, most experts dealing with scientific computational simulations require a specialized and customized Problem Solving Environment (PSE) with easy-to-use graphical user interfaces integrated with large-scale computing resources for their experiments. It is also important to provide adequate middleware support to drag out best performance of an application from the environment. To fulfill these requirements, we propose a workflow-enabled integrated e-Science portal system supporting interactivities for aerodynamic computing simulations, which are driven to diverse multiple execution stages depending on convergence status of variables. The portal allows scientists to manage whole life-cycle of experiments from designing, deploying, executing, and monitoring a scientific application in aerodynamic research on e-Science environment. Scientists easily extend various types of their experiments with less risk of design errors and save their time for learning curve to handle computing resources to optimize the performance of experiments. Workflow editor presents interactive, high-level web-based front end to scientist and monitoring service shows the step of the execution of workflow in real-time so that scientists in any level of expertise can check the intermediate data during experiments.
