environments, developing, deploying, and executing applications over the
grid is a challenge. Dependability is a key factor for grid computing,
and dependability has great inl uence on the practice of grid platform. To
target the practical vision of the ChinaGrid, dependability research in the
ChinaGrid is very active, covering the platform through to applications.
The remainder of this chapter is organized as follows: the next section
gives an illustration of the vision and mission of the ChinaGrid project;
this is followed by an illustration of the ChinaGrid Support Platform; the
application platforms in the ChinaGrid are presented next; and dependa-
bility research is discussed in the i nal section, covering grid monitoring,
hardware and middleware fault tolerance, grid fault detection, and
application fault tolerance.

In 2002, China's Ministry of Education (MoE) launched the largest grid
computing project in China, called the ChinaGrid project, aiming to
provide a nationwide grid computing platform and services for research
and education purpose among 100 key universities in China. The vision
for the ChinaGrid project is to deploy the largest, most advanced and most
practical grid computing project in China or even worldwide.
The underlying infrastructure for the ChinaGrid project is the CERNET,
which began to run from 1994, covering 800 more universities, colleges,
and institutes in China. Currently, it is the second largest nationwide
network in China. The bandwidth of the CERNET backbone is 2.5 Gbps,
and it is connected by seven cities called local network centers. The band-
width of the CERNET local backbone is 155 Mbps.
The ChinaGrid project is a long-term project with three different stages.
The i rst stage period was from 2002 to 2005, covering 12 top universities
in China. They are: Huazhong University of Science and Technology
(HUST), Tsinghua University (THU), Peking University (PKU), Beihang
University (BUAA), South China University of Technology (SCUT),
Shanghai Jiao Tong University (SJTU), Southeast University (SEU), Xi'an
Jiaotong University (XJTU), National University of Defense Technology
(NUDT), Northeastern University (NEU), Shandong University (SDU),
and Sun Yat-Sen University (ZSU). The focus for the i rst stage of the
ChinaGrid project was on platforms and applications in the computation
grid (e-Science). These applications covered all scientii c disciplines, from
life sciences to computational physics. The second stage of the ChinaGrid
project was from 2005 to 2007, covering 20-30 key universities in China.
The focus extended from computational grid applications to information
service grid (e-Info), including applications for distance learning grid,
