 THE KEY COMPONENTS OF GRID COMPUTING

Resource management: a grid must be aware of what resources are available for different tasks 

Security management: the grid needs to take care that only authorized users can access and use the available resources

Data management: data must be transported, cleansed, parceled, and processed 

Services management: users and applications must be able to query the grid in an effective and efficient manner 

More formally, a grid computing environment may be thought of as a computer system made up of several logical hierarchical layers. The figure depicts these layers. Grid fabric resources, grid security infrastructure, core grid middleware, user-level middleware and resource aggregators, grid programming environment and tools, and grid applications are all part of it.

The major components of a grid computing system can be identified into various categories from different perspectives as follows:

  • Functional view
  • Physical view
  • Service view


Basic elements of a grid from a functional view are decided depending on the grid design and its expected use. Some of the functional constituents of a grid are:

  • Security (Grid security infrastructure),
  •  Resource Broker,
  • Scheduler,
  • Data Management,
  • Job and resource management,
  • Resources.

Based on the physical viewpoint, a grid is a collection of:

  • Networks,
  • Computation (Processors),
  • Storage,
  • Scientific Instruments,
  • Software and Licenses.


The service view of grid computing adheres to the concepts of:

  • Service-oriented architectures (SOA) 
  • Simple Object Access Protocol (SOAP)
  • Web services standards
  • Web Services Description Language (WSDL)
  • Web Services Inspection Language (WSIL)
  • Universal Description, Discovery, and Integration (UDDI)
  • .NET
  • Web Services Resource Framework (WSRF)

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage virtualization is a system administration practice that allo
