    Our Missions and Frame of Mind

    The foundation of the Computational Science and Engineering Division was approved on July 8, 2002, and an organization meeting was held at the General Assembly in the fall of 2002. That was the year when the first generation Earth Simulator started operating, sending shock waves around the world as the beginning of the era of “computonic.” 15 years have passed since then, and the performance of computers has so far attained an astonishingly sophisticated level. Until recently, teraflop computing capabilities were limited to only a few computational environments, such as super computers, but now, a general user can exclusively use this function on his/her desk.

    Under this technological circumstance when people’s expectations for computational science and technology are increasing, what the mission of the members of the Computational Science and Engineering Division should be? I believe that is to promote discussions about topics common to the two fields of computational science and computational engineering.

    Modeling & Simulation (M&S) are the keywords in computational science for getting new insights into physical phenomena through computation using various approaches including Multi-Scale, Multi-Physics and Direct Numerical Simulation (DNS). In computational engineering, the keywords are Architecture & Algorithm, which focus on finding new values in various problems using high performance computing (HPC), numerical approaches and visualization techniques.

    Computational science and technology are, so to say, two wheels of a cart, and their effects may be maximized through working in a coordinated manner. In this context, it is essential for experts in various scientific fields to bring up their ideas, exchange opinions and find new perspectives. That is the exact reason for founding the Computation Science & Engineering Division — providing a place and opportunities for experts. I sincerely hope all the members will make sincere efforts to present their ideas and make lively discussions in general sessions to develop new perspectives.

    In addition, the AESJ recently issued a standard for Verification & Validation (V&V), which were our long-lasting theme of discussions. Standardization has been addressed several times at the organized session of the AESJ, but from now on, discussions on cases of implementations in individual fields may be expected. The members are strongly encouraged to offer information on this matter.

    Finally, your comments and requests are welcome. You may kindly make use of the steering committees or the inquiry form provided at our website. The steering committees are willing to serve the members, and implement plans useful for you. They may have shortcomings, but strive to run the Computational Science and Engineering Division with the best of intentions. Your understanding and cooperation would be very much appreciated.
