• Questions

3
What is it

• Geographicaly distributed (super computers, large
  databases, high end instruments)
• Resource sharing
• Coordinated problem solving
• Dynamic milti-institutional virtual organizations

4
Related to and how

• Distributed Proccessing
• Parallel Processing

5
Why use it

• Larger scale problems
• More resources
• Simular uses to a parallel environment
• Community work

6
Who uses them

• Application programmers
• Scientists
• Normal users accessing tools on the grid
• DOD, NASA, DOE, NSF

7
How this affects Software Development

• Software Development is a broad topic, lots of
  sub projects in fields such as
• Science
• Medicine
• Engineering
• Military
• School
• Media

8
How this affects Software Development cont

• Greater resources
• More complex applications
• More work to make scientific applications
• New areas of application development
• Web development
• Distance learning applications

9
How This affects Software Development cont

• Greater community
• Impact software development procedures
• Impact software reuse
• Impact software debugging
• Impacts the field with more people working
  together in the same area
• Distributed workers
• Military example
• Application Example

10
Issues with Grid computing

• No standards
• Globus Project
• Close work with industry and science
• Development of API and SDK
• Globus Toolkit

11
Application Programming Interface

• What is it
• Why is it used
• How it impacts software development
• Examples
• MPI
• openMP
• GSS API

12
Software Development Kit

• Specific API
• An API can have multiple SDKs

Closing Remarks

• Many companies or governmental agencies investing
  research in this area
• It just rocks
• New field
• Potential only theorized
• I feel that it will exceed the potential
