Whats CGSP?

• ChinaGrid Supporting Platform, a grid middleware
  for ChinaGrid
• Follows the WS-Resource Framework (WSRF) and Open
  Grid Service Architecture (OGSA)
• Supports four major grid applications of
  ChinaGrid
• Developed by a joint working group from HUST,
  THU, PKU, BUAA, SJTU, and other universities in
  ChinaGrid

CGSP Architecture
9
Service Container

• Runtime environment for CGSP
• Based on GT4 Core
• Hot deploy
• Remote deploy
• Service Monitoring

10
Information Center

• A logical center to publish and discover all
  kinds of information of grid resources
• Functions
• To connect all domains
• Manage (Join/Quit) the topology
• To support powerful view of grid resources
• global view
• user-related view

11
Execution Manager

• Enables applications to have coordinated access
  to underlying resources
• Fundamental job management
• Job submission , Job scheduling
• Uniform interface of job creation and monitoring
• WS, WSRF, JSDL, Workflow Service
• Support four types of job submission
• Generic Job Submission (for WS/WSRF)
• Composite Job Submission (for workflow)
• JSDL Job Submission (for legacy program)
• GRS Application Submission (for legacy program)

12
Execution Manager

• General Running Service (GRS)
• a WSRF-compliant service, providing computing
  service for legacy programs
• Supports MPI Program with PBS-supported cluster
• Provides auto-deployment of Legacy program
  together with the CGSP Service Container
• Deployed on each computing node of ChinaGrid

13
Execution Manager

• Workflow Support
• Follows BPEL4WS 1.1 specification
• Supports workflow deployment, execution, control
  and monitoring
• Balances the workload with a distributed workflow
  engine
• Supports composite WSRF services

14
Data Manager

• Grid File System Service
• Enables users to have their own virtual data
  space over Grid
• Supports file operations
• Make/Remove directories
• Upload/Copy/Remove/Download files
• Browse/Search files/directories
• Grid Database Service
• Packs a database into a grid service
• Provides an uniform interface to access and
  integrate distributed and heterogeneous databases

15
Programming Interface

• GridPPI Grid Parallel Programming Interface
• Helps to write parallel program on ChinaGrid at
  service-level
• Provides MPI-like APIs
