9. Distributed Computing
•“A Distributed system consists of multiple autonomous
computers that communicate through a computer
network.
•“Distributed computing utilizes a network of many
computers, each accomplishing a portion of an overall
task, to achieve a computational result much more
quickly than with a single computer.”
•“Distributed computing is any computing that involves
multiple computers remote from each other that each
have a rolein a computation problem or information
processing.”

10. •A distributed system is one in which hardware or
software components located at networked
computers communicate and coordinate their
actions only by message passing.
•In the term distributed computing, the word
distributed means spread out across space. Thus,
distributed computing is an activity performed on a
spatially distributed system.
•These networked computers may be in the same
room, same campus, same country, or in different
continents

12. History
•1975 –1985
–Parallel computing was favored in the early years
–Primarily vector-based at first
–Gradually more thread-based parallelism was introduced
–The first distributed computing programs were a pair of
programs called Creeper and Reaper invented in 1970s
–Ethernet that was invented in 1970s.
–ARPANET e-mail was invented in the early 1970s and
probably the earliest example of a large-scale distributed
application.

13. History
•1985 -1995
–Massively parallel architectures start rising and message
passing interface and other libraries developed
–Bandwidth was a big problem
–The first Internet-based distributed computing project was
started in 1988 by the DEC System Research Center.
–Distributed.net was a project founded in 1997 -considered
the first to use the internet to distribute data for
calculation and collect the results

14. History
•1995 –Today
–Cluster/grid architecture increasingly dominant
–Special node machines eschewed in favor of COTS
technologies
–Web-wide cluster software
–Google take this to the extreme (thousands of
nodes/cluster)
–SETI@Homestartedin May 1999 -analyze the radio
signals that were being collected by the Arecibo Radio
Telescope in Puerto Rico.

15. Goal
•Making Resources Accessible
–Data sharing and device sharing
•Distribution Transparency
–Access, location, migration, relocation, replication,
concurrency, failure
•Communication
–Make human-to-human comm. easier. E.g.. : electronic
mail
•Flexibility
–Spread the work load over the available machines in the
most cost effective way
•To coordinate the use of shared resources
•To solve large computational problem

16. Characteristics
•Resource Sharing
•Openness
•Concurrency
•Scalability
•Fault Tolerance
•Transparency

17. Architecture
•Client-server
•3-tier architecture
•N-tier architecture
•loose coupling, ortight coupling
•Peer-to-peer
•Space based

18. Application
•Examples of commercial application :
–Database Management System
–Distributed computing using mobile agents
–Local intranet
–Internet (World Wide Web)
–JAVA Remote Method Invocation (RMI)

19. Distributed Computing Using Mobile
Agents
•Mobile agents can be wandering around in a
network using free resources for their own
computations.

20. Local Intranet
•A portion of Internet that is separately
administered & supports internal sharing of
resources (file/storage systems and printers) is
called local intranet.

21. Internet
•The Internet is a global system of interconnected
computer networks that use the standardized
Internet Protocol Suite (TCP/IP).

22. Categories of Applications in
distributed computing
•Science
•Life Sciences
•Cryptography
•Internet
•Financial
•Mathematics
•Language
•Art
•Puzzles/Games
•Miscellaneous
•Distributed Human Project
•Collaborative Knowledge Bases
•Charity

23. Example of applications
•Internet –Gomez Distributed PEER Client
(peerReview)
–Evaluatethe performance of large websites to find
bottlenecks.
•Life Sciences -Compute Against Cancer
®
(CAC)
–Create immediate impact in the lives of cancer
patients and their families today, while at the
same time empowering the research that will
result in improved therapies —and perhaps even
the cure.

24. Example of applications
Collaborative Knowledge Bases –Wikipedia
A collaborative project to produce a complete a free
encyclopedia from scratch.
The encyclopedia is available in manynon-English languages.
Distributed Human Projects-Open Mind Indoor
Common Sense
Helpteach indoor mobile robots to be smarter. It will
create a repository of knowledge which will enable
people to create more intelligent mobile robots for use
in home and office environments.

25. Advantages
•Economics:-
–Computers harnessed together give a better price/performance ratio
than mainframes.
•Speed:-
–A distributed system may have more total computing power than a
mainframe.
•Inherent distribution of applications:-
–Some applications are inherently distributed. E.g., an ATM-banking
application.
•Reliability:-
–If one machine crashes, the system as a whole can still survive if you
have multiple server machines and multiple storage devices
(redundancy).
•Extensibility and Incremental Growth:-
–Possible to gradually scale up (in terms of processing power and
functionality) by adding more sources (both hardware and software).
This can be done without disruption to the rest of the system.

26. Disadvantages
•Complexity :-
–Lack of experience in designing, and implementing a distributed
system. E.g. which platform (hardware and OS) to use, which language
to use etc.
•Network problem:-
–If the network underlying a distributed system saturates or goes
down, then the distributed system will be effectively disabled thus
negating most of the advantages of the distributed system.
•Security:-
–Security is a major hazard since easy access to data means easy access
to secret data as well.

27. Conclusion
•The concept of distributed computing is the most
efficient way to achieve the optimization.
•Distributed computing is anywhere : intranet, Internet
or mobile ubiquitous computing (laptop, PDAs, pagers,
smart watches, hi-fi systems)
•It deals with hardware and software systems, that
contain more than one processing / storage and run in
concurrently.
•Main motivation factor is resource sharing; such as files
, printers, web pages or database records.
•Grid computing and cloud computing are form of
distributed computing.
