Image Processing Grid

• Three-dimension reconstruction of digital virtual human being (HUST)

• Medical image diagnosis (ZSU)

• Remote sensing image processing（NUDT）

BioGridhttp://biogrid.hpcgrid.cs.tsinghua.edu.cn

Only two things for users:

1. Submit bioinformatics jobs through the web

2. Wait for the results

Users needs not to care about the job scheduling, task monitoring and task management
