7. High-performance computing
• High-performance computing (HPC) is the ability to process data and
perform complex calculations at high speeds
• One of the best-known types of HPC solutions is the supercomputer. A
supercomputer contains thousands of compute nodes that work together to
complete one or more tasks. This is called parallel processing. It’s similar to
having thousands of PCs networked together, combining compute power to
complete tasks faster.
• HPC solutions have three main components:
• Compute
• Network
• Storage

15. PARALLEL COMPUTING

16. Parallel Computing
• is a type of computing architecture in which several processprs
simultaneously execute multiple calculations
• Divides larger problem into small problems and executes parallely
• classic computers solve problems sequentially
• Performance is improved by increasing clock frequency
• But this increases power consumption
• processor vendors decided to provide multiple cpu cores on the
same processor chip each capable of executing seperate
binstructions
• Parallel computing uses multiple computer cores to attack several
operations at once. Unlike serial computing, parallel architecture can
break down a job into its component parts and multi-task them.
• Eg:watching Youtube-displays similar searches(big data)
• Thousands of processor cores that can analyse all big data in
parallel

17. PARALLEL COMPUTING
• Sequential parallel
• Single processor Multiple processors
• low performance High performance
• data transfer Bit by bit data transfer bytes

18. Benefits of parallel computing
• 1. Parallel computing models the real
world
• 2. Saves time
• 3. Saves money
• 4. Solve more complex or larger
problems
•

19. Few examples below of how parallel processing drives
our world.
• Smartphones.
• The iPhone 5 has a 1.5 GHz dual-core processor. The iPhone 11
has 6 cores. The Samsung Galaxy Note 10 has 8 cores. These
phones are all examples of parallel computing....
• Laptops and desktops. ...
• ILLIAC
• This was the first “massively” parallel computer, built largely at the
University of Illinois. The machine was developed in the 1960s with
help from NASA and the U.S. Air Force. It had 64 processing
elements capable of handling 131,072 bits at a time

• The Space Shuttle program uses 5 IBM AP-101 computers in
parallel [8]. They control the shuttle’s avionics, processing large
amounts of fast-paced real-time data. The machines can perform
480,000 instructions per second. The same system has also been
used in F-15 fighter jets and the B-1 bomber

20. • American Summit supercomputer. ...
• most powerful supercomputer on Earth is the American Summit. The machine was
built by the U.S. Department of Energy at their Oak Ridge National Laboratory. It’s a
200-petaFLOPS machine that can process 200 quadrillion operations per second. If
every human on earth did one calculation per second, they’d need 10 months to do
what Summit can do in a single second
• SETI. ...
• Does life exist on other planets? So far, the best way to find out is to listen for radio
signals from other worlds. The Search for Extraterrestrial Intelligence (SETI) monitors
millions of frequencies all day and night. To ease the workload, SETI uses parallel
computing through the Berkeley Open Infrastructure for Network Computing (BOINC)
• Bitcoin. ...
• is a blockchain tech that uses multiple computers to validate transactions. You’ll
use blockchain to do almost anything money-related in the coming years. Blockchain
and Bitcoin don’t work without parallel computing
• The Internet of Things (IoT)

21. Parallel vs distributed computing
• Shared memory parallel computers use multiple processors to
access the same memory resources. Examples of shared memory
parallel architecture are modern laptops, desktops, and
smartphones.
• Distributed memory parallel computers use multiple processors,
each with their own memory, connected over a network. Examples
of distributed systems include cloud computing, distributed rendering
of computer graphics, and shared resource systems like SETI
• Hybrid memory parallel systems combine shared-memory parallel
computers and distributed memory networks. Most “distributed
memory” networks are actually hybrids. You may have thousands of
desktops and laptops with multi-core processors all connected in a
network and working on a massive problem.

COMPUTING

26. DISTRIBUTED COMPUTING

27. Distributed computing is also a computing system that
consists of multiple computers or processor machines
connected through a network, which can be
homogeneous or heterogeneous, but run as a single
system.
The connectivity can be such that the CPUs in a
distributed system can be physically close together and
connected by a local network, or they can be
geographically distant and connected by a wide area
network.
The heterogeneity in a distributed system supports
any number of possible configurations in the processor
machines, such as mainframes, PCs, workstations, and
minicomputers.
Examples :Internet,Intranet

28. An intranet is a computer network
for sharing information, easier
communication, collaboration
tools, operational systems, and
other computing services within
an organization.

30. Advantages
• Resource Sharing
• concurrency-able to execute more than one task
• Scalability- increase the performance of
computing
• Transparency-hides complexity to users
• Redundancy or replication: Here, several
machines can provide the same services, so
that even if one is unavailable (or failed), work
does not stop because other similar computing
supports will be available.

31. • Developing a single system is very difficult
• Eg:Facebook
Google

32. Applications

42. Grid computing
• Grid computing is a group of networked computers which work
together as a virtual supercomputer to perform large tasks, such as
analysing huge sets of data or weather modeling.
• The advantage is that the data is stored in memory across
all computers in the data grid, so all data accesses are very fast.
• Grid computing works by running specialized software on every
computer that participates in the data grid. The software acts as the
manager of the entire system and coordinates various tasks across
the grid.
• Grid computing is especially useful when different subject matter
experts need to collaborate on a project
• For example, a research team might analyze weather patterns
in the North Atlantic region, while another team analyzes the
south Atlantic region, and both results can be combined to
deliver a complete picture of Atlantic weather patterns.

43. GRID COMPUTING
1) Its ability to make use of unused computing power, and
thus, it is a cost-effective solution (reducing investments,
only recurring costs)
2) As a way to solve problems in line with any HPC-based
application
3) Enables heterogeneous resources of computers to work
cooperatively and collaboratively to solve a scientific
problem
4) Researchers associate the term grid to the way electricity
is distributed in municipal areas for the common man. In this
context, the difference between electrical power grid and
grid computing is worth noting

Adleman's experiment, the Hamiltonian Path Problem was implemented
notationally as “travelling salesman problem”.

representing a city that had to be visited. Every one of these fragments is
capable of a linkage with the other fragments created.

94. NANO COMPUTING
Nano computing refers to computing systems
that are constructed from nano scale
components.
The silicon transistors in traditional computers
may be replaced by transistors based on
carbon nano tubes.
The successful realization of nano computers
relates to the scale and integration of these
nano tubes or components.
The issues of scale relate to the dimensions
of the components; they are, at-most, a few
nanometers in at least two dimensions.

95. NANO COMPUTING
The issues of integration of the components
are twofold:
1) The manufacture of complex arbitrary
patterns may be economically infeasible
2) Nano computers may include massive
quantities of devices.
Researchers are working on all these issues
to bring nano computing a reality.

96. NANO COMPUTING
Nanocomputer refers to a computer smaller
than the microcomputer, which is smaller than
the minicomputer.
Microelectronic components that are at the
core of all modern electronic devices employ
semiconductor transistors.
The term nanocomputer is increasingly used
to refer to general computing devices of size
comparable to a credit card. Modern Single-
Board Computers such as the Raspberry
Pi and Gumstix would fall under this
classification.
Arguably, Smartphones and Tablets would

97. NANO COMPUTING
EXAMPLES
Without nanotechnology, we wouldn't have
many of the electronics we use in everyday
life. Intel is undoubtedly a leader in tiny
computer processors, and the latest
generation of Intel’s Core processor
technology is a 10-nanometer chip. When
you think a nanometer is one-billionth of a
meter, that’s incredibly impressive!

98. Quantum
Computing

99. • Quantum computers are trying to overcome
supercomputers.But still research is going on
• In 1998 Isaac Chuang of the Los Alamos National Laboratory,
created the first quantum computer (2-qubit) that could be
loaded with data and output a solution.
• Quantum computing is the use of quantum phenomena such
as superposition and entanglement to perform computation.
• Computers that perform quantum computations are known as
quantum computers.
• Quantum computers perform calculations based on the
probability of an object's state before it is measured - instead
of just 1s or 0s - which means they have the potential to
process exponentially more data compared to classical
computers.
• A single state - such as on or off, up or down, 1 or 0 - is
called a bit.
• A quantum computer encodes information into quantum states
and computes by performing quantum operations on it.
Quantum Computing

100. • The “IBM Q Experience,” launched in 2016,
now consists of 15 publicly available quantum
computers ranging from five to 53 qubits in
size.
• The quantum computer can do GBS 100 trillion
times faster than a classical supercomputer
• The quantum computer has 233 megabytes of
hard disk space
• QCL (Quantum Computer Language) is the
most advanced implemented quantum
programming language.

101. Companies Implementing Quantum

be cooled to under 1 kelvin using a dilution
refrigerator.
2.Quantum computers are believed to be
able to solve certain computational
problems, such as integer
factorization (which underlies RSA
encryption), substantially faster than
classical computers.

103. What is quantum computing?
• An ordinary computer chip uses bits.
These are like tiny switches, that can
either be in the off position – represented
by a zero – or in the on position –
represented by a one. Every app you use,
website you visit and photograph you take
is ultimately made up of millions of these
bits in some combination of ones and
zeroes.
• There are certain things exists like

104. How do quantum computers
work?
• Instead of bits, quantum computers use qubits.
Rather than just being on or off, qubits can also
be in what’s called ‘superposition’ – where
they’re both on and off at the same time, or
somewhere on a spectrum between the two.
• Eg:Take a coin.When u flip their is uncertainity
always
• Superposition is like a spinning coin, and it’s
one of the things that makes quantum
computers so powerful. A qubit allows for
uncertainty.

105. • Electrons and photons sometimes behave
like waves, and sometimes like particles.
Until they’re measured, they can even
appear to be in both states simultaneously,
or in two places at once – a phenomenon
known as quantum superposition
• Feynman was the first to realise the
implications.
• That’s a problem for classical computers.
They work using bits – tiny switches that
How do quantum computers
work?

106. • If we want to find a path of 10 cities
supercomputer can solve easily in
seconds but if I add2000 cities it may take
2000 years
• Quantum computers have the potential to
rapidly accelerate the development of
artificial intelligence. Google is already
using them to improve the software of self-
driving cars.

107. Applications
