摘要

In this paper we present a scientific computing system named MobileLab which is designed for pervasive computing on the Internet. A middleware named TOM (stands for Tsinghua Operation Middleware) is designed and employed in MobileLab as a key to access the grid. Based on TOM, MobileLab can access the computational resource transparently; distribute the components to optimize the computation procedure and computation can be moved from one node to another. To use a middleware model in the architecture of scientific computing system is our new approach corresponding to the grid computing and mobile computing.
