Massive Data Processing Grid
Massive Data Processing (MDP) Grid includes three data-intensive grid
applications: high-energy physics computing, the alpha magnetic spec-
trometer (AMS) experiment, and the University Digital Museum Grid.
High-energy physics computing based on MDPGrid is a solution for the
processing and analyzing of the massive amounts of data generated by
CERN's ATLAS experiment, the Sino-Italy cosmic ray experiment at
YangBaJing, Tibet, and the BEPC/BES project at Shandong University.
The AMS experiment project is a large-scale physics experiment on the
International Space Station (ISS), the main purpose of which is to look for
antimatter, search for the source of dark matter, and measure the source
of cosmic rays. Space Detector Type Two (AMS-02) sent the space shuttle
in 2005 to the ISS to carry on the experiment for three to i ve years. The
data collected by AMS-02 will be eventually stored, indexed, and ana-
lyzed in the Science Operation Centers (SOCs). The Data Processing Center
in Southeast University will be able to directly receive the data sent by
NASA and carry on data analysis independently. Currently, the SOC in
South East University has put up a grid platform SEUGrid for the Monte-
Carlo simulation computing of AMS-02 MC.
The University Digital Museum Grid aims to integrate the enormous
dispersed resources of various digital museums, to share the resources
effectively and eliminate the information island, to i lter and classify the
collection information, and to provide an appropriate information service
to users according to their knowledge levels and motivation through a
unii ed grid portal. For the time being, the university digital museums
involved include the Digital Museum of Aeronautics and Astronautics
(BUAA) [27], the Archaeological Digital Museum (SDU) [28], the Geoscience
Digital Museum (NJU) [29], and the Mineralogical Digital Museum (KUST)
[30]. The services and resources in each university digital museum
compose one site. The collection provider service gives access to digital
museum collections as raw data.

To make the ChinaGrid practical, dependable grid computing research is
very active, which covers grid infrastructure dependability through to
application dependability. In the ChinaGrid, there are some systems
related to dependable grid computing developed and released; for example,
ChinaGrid SuperVison [31,32]. There are also some specii c models
presented; for example, DRIC provides an adaptive application fault-
tolerant model [33]. The selected systems and models are presented in the
Grid Dependable Research
