ASSIGNMENT
DRIVE SUMMER 2016
PROGRAM BSc IT
SEMESTER FIFTH
SUBJECT CODE & NAME BT9002, Grid Computing
BK ID B1189
CREDITS 4
MARKS 60
Note: Answer all questions. Kindly note that answers for 10 marks questions should be
approximately of 400 words. Each question is followed by evaluation scheme.
Question.1. What are the components that are necessary to form a
grid?
Answer:An electric grid is a network of synchronized power providers and consumers that are
connected by transmission and distribution lines and operated by one or more control centers.
When most people talk about the power "grid," they're referring to the transmission system for
electricity.
The continental United States does not have a national grid. Instead, there are three grids: the
Eastern Interconnect, the Western Interconnect and the Texas Interconnect. In Alaska and Hawaii,
several smaller systems interconnect parts of each state.
Increasingly, intelligence is being built into
Question.2. Briefly explain the various layers of grid architecture.

2. Answer:The grid is a metacomputing infrastructure that brings together computers (PCs,
workstations, server clusters, supercomputers,
Question.3. Explain autonomic computing and its properties.
Answer:Autonomiccomputingreferstothe self-managing characteristics of distributed computing
resources, adapting to unpredictable changes while hiding intrinsic complexity to operators and
users.
Startedby IBMin 2001, thisinitiative ultimatelyaims to develop computer systems capable of self-
management,toovercome the rapidlygrowingcomplexityof computingsystems management, and
to reduce the barrier that complexity poses to further growth. The system makes decisions on its
own,usinghigh-level policies;itwill constantlycheckandoptimizeitsstatusandautomaticallyadapt
itself to changing conditions. An autonomic computing framework is composed of autonomic
components (AC) interacting with each other. An AC can be modeled in terms of two main control
loops (local and global) with sensors (for self-monitoring),
Question.4. Briefly explain the scenarios and use case situation
analysis in virtual organization grid portal.
Answer: Successful realization of the Open Grid Services Architecture (OGSA) vision of a broadly
applicable andadoptedframeworkfordistributed system integration requires definition of a wide
varietyof Grid use case scenariosof bothe-science ande-businessapplications.Use cases described
inthisdocument cover commercial infrastructure and application topics (Commercial Data Center,
Online MediaandEntertainment,Intergrid),scientificinfrastructure andapplicationtopics(National
Fusion Collaboratory, Severe Storm Modeling, and Virtual Organization Grid Portal), essential grid
technologies (Grid Resource Reseller,
Question.5. Explain OGSA core platform components with diagram.
Answer:Open Grid Services Architecture (OGSA) is a set of standards defining the way in which
information is shared among diverse components of large, heterogeneous grid systems. In this
context, a grid system is a scalable wide area network (WAN) that supports resource sharing and
distribution. OGSA is a trademark of the Open Grid Forum.
Question.6. Briefly explain the major components of OSGI.net.

3. Answer:OSGi.NET helps .NET developers to reform and build software systems consisting of
individual logical physical modules which are communicating with each others by Service Bus (a
combinationof pre-definedservice interfaces,couldadd/get/remove specified service instance) or
by extension point/extension (a mechanism that allow one module to publish extra infomations
(extension,xmlformat) to another who subscribes the same topic (same extension ponit name) in
oderto extendthe subscriberdynamically.Modules (always called "Bundle") are under the control
of OSGi.NET Runtime with life-cycle management (Installed, Resolved, Starting, Active, Stopping,
Uninstalled) which is accessble by others when want
