ShanghaiGrid in action: The first stage projects towards digital city and city grid

The nearest goal of ShanghaiGrid is going to connect all supercomputers in this metropolis together to form a sharing environment for massive storage and grid computing. The first stage projects of ShanghaiGrid comprise four sub-projects, including: • research on environment, protocols and standards of information grid infrastructure; • development of system software for information grid and establishment of four major intra-grid nodes; • development of peer-to-peer based virtual research platform; • research on the application of grid based traffic-jam control and guidance. This paper introduces the background of ShanghaiGrid, provides a glimpse at features and challenges of its sub-projects, and summarises the general goal of them.
