Guest Editors´ Introduction: Scientific Applications of Grid Computing, Part II

As with the examples provided in the September/October 2005 issue, these articles describe cutting-edge research in scientific grid computing. Although it´s also possible to use grid computing to address small-scale scientific computing needs, our aim in assembling both these issues has been to focus on large-scale work--indeed, work that can’t be done in any other way, for want of computational resources. In the end, we believe that grid computing´s impact on computational science ought to be judged by what new natural science it enables us to discover.
