Grid Computing

• Taiwan UniGrid
• A university Grid plaftorm in Taiwan
• Medicare Grid
• A Grid platform for Medicare services
• Pisces
• A P2P Meta-Grid System

20
Taiwan Unigrid Services
21
Summary of Taiwan Unigrid

• The first Grid system designed by researches in
  Taiwan.
• Over 20 organizations join this project and forms
  a large grid platform.
• Provides a series of services and web-based user
  interfaces for users to use its computing and
  storage resources with ease.

22
Medicare Grid Platform

• Medicare Computation Grid Platform
• Fulfill the computing requirements of hospitals
  and Medicare services
• Medicare Data Grid Platform
• Store the EHR with efficient search and
  manipulation capability
• Medicare Grid Management System
• Standardize the EHR and provide translation
  mechanism for different format

23

24
Medicare Grid Services

• Decision Support System
• Help physicians or medical professionals to make
  better decisions for treatment
• Intelligent Mobile System
• Establish an active RFID environment for context
  acquisition of individuals, environments
  variables and their associated values
• Personal Health Protection System
• Developed for measuring patients physiological
  conditions under a convenient and comfortable
  circumstance

25
Summary of Medicare Grid

• Integrate computing and storage resources to form
  a Medicare-Grid platform and propose an EHR
  sharing mechanism based on it.
• More than 500,000 real EHR samples provided by
  Taichung Veterans General Hospital are stored in
  Medicare Grid platform.
• Base on the Medicare Grid platform, three
  Medicare applications has been developed to
  improve the in-hospital medical services.

26
Pisces A P2P Meta-Grid System

• Pisces is a P2P meta-grid system towards the
  collaboration with automatic grids
• To achieve the integration of distributed
  resources among different grid systems
• We propose a meta-grid framework based on the
  super-peer network to form self-management
  autonomies in Pisces

27
System Architecture

• A cross-grid layer built on top of existing
  autonomic grid systems to realize the
  Grid-to-Grid federation

28
Summary of Pisces

• Pisces achieves the collaboration through the
  federation of autonomic grid systems.
• Pisces can harmonize autonomic grids without
  bringing a heavy burden on existing grid systems.
• The scalability of a grid federation can be
  improved with the convergence of grid systems and
  P2P paradigm.
