Abstract
The development of the high performance computer and network, and accumulation of information contents, such as data and software attained development of the advanced design system. However, in order to make this possibility actual, development of large-scale and complicated software is indispensable, and the new architecture of the software for a design is needed. In this paper, the new architecture, which integrates the existing information contents on a high performance computer and network environment, is proposed. This new architecture is called taskflow. While establishing the concept of a task flow, the taskflow was applied to the materials design, and the virtual experiment system for materials design was developed. The concept of taskflow and virtual experiment system are explained. The efficiency of the new architecture of the software for a design was confirmed.
