What is a Supercomputer?
A supercomputer is a computer at the frontline of contemporary processing capacity
particularly speeds of calculation. A large computer or collection of computers that act as onelarge computer capable of processing enormous amounts of data. Supercomputers are used
for very complex jobs such as nuclear research or collecting and calculating weather patterns.
Below is an example picture of a super computer at the William R. Wiley Environmental
Molecular Sciences Laboratory, the Linux-based supercomputer is composed of nearly 2,000
processors. Courtesy: Pacific Northwest National Laboratory. Supercomputers are the
bodybuilders of the computer world. They boast tens of thousands of times the computing
power of a desktop and cost tens of millions of dollars. They fill enormous rooms, which are
chilled to prevent their thousands of microprocessor cores from overheating. And they
perform trillions, or even thousands of trillions, of calculations per second.
All of that power means supercomputers are perfect for tacklingbig scientific problems,from
uncovering the origins of the universe to delving into the patterns of protein folding that
make life possible. Here are some of the most intriguing questions being tackled by
supercomputers today.
A supercomputer is a computer that performs at or near the currently highest operational rate
for computers. A supercomputer is typically used for scientific and engineering applications
that must handle very large databases or do a great amount of computation (or both).
At any given time, there are usually a few well-publicized supercomputers that operate at
extremely high speeds. The term is also sometimes applied to far slower (but still
impressively fast) computers. Most supercomputers are really multiple computers that
performparallel processing. In general, there are two parallel processing approaches:symmetric multiprocessing (SMP)and massively parallel processing (MPP).
IBM'sRoadrunner is the fastest supercomputer in the world, twice as fast asBlue Gene and
six times as fast as any of the other current supercomputers. At the lower end of
supercomputing, a new trend called clustering, takes more of a build-it-yourself approach to
supercomputing. TheBeowulf Project offers guidance on how to put together a number of
off-the-shelf personal computer processors, usingLinux operating systems, and

interconnecting the processors withFast Ethernet.Applications must be written to manage
the parallel processing.
Perhaps the best-known builder of supercomputers has been Cray Research, now a part of
Silicon Graphics. In September 2008, Cray and Microsoft launched CX1, a $25,000 personal
supercomputer aimed markets such as aerospace, automotive, academic, financial services
and life sciences. CX1 runs Windows HPC (High Performance Computing) Server 2008.
In the United States, somesupercomputer centres are interconnected on an Internet
backbone known asvBNS or NSFNet. This network is the foundation for an evolving
network infrastructure known as the National Technology Grid.Internet2 is a university-led
project that is part of this initiative.
Supercomputers were introduced in the 1960s, made initially and, for decades, primarily by
Seymour Cray at Control Data Corporation (CDC), Cray Research and subsequent companies
bearing his name or monogram. While the supercomputers of the 1970s used only a few
processors, in the 1990s machines with thousands of processors began to appear and, by the
end of the 20th century, massively parallel supercomputers with tens of thousands of "off-
the-shelf" processors were the norm. As of November 2013, China's Tianhe-2 supercomputer
is the fastest in the world at 33.86 petaFLOPS.
Systems with massive numbers of processors generally take one of two paths: In one
approach (e.g., in distributed computing), a large number of discrete computers (e.g., laptops)
distributed across a network (e.g., the internet) devote some or all of their time to solving a
common problem; each individual computer (client) receives and completes many small
tasks, reporting the results to a central server which integrates the task results from all the
clients into the overall solution. In another approach, a large number of dedicated processorsare placed in close proximity to each other (e.g. in a computer cluster); this saves
considerable time moving data around and makes it possible for the processors to work
together (rather than on separate tasks), for example in mesh and hypercube architectures.
The use of multi-core processors combined with centralization is an emerging trend; one can
think of this as a small cluster (the multicore processor in a smartphone, tablet, laptop, etc.)
that both depends upon and contributes to the cloud.

particles and of the origin and nature of the universe. Supercomputers have become an
indispensable tool in weather forecasting: predictions are now based on numerical models. As
the cost of supercomputers declined, their use spread to the world ofonline gaming. In
particular, the 5th through 10th fastest Chinese supercomputers in 2007 were owned by a
company with online rights inChina to theelectronic gameWorld of War craft, which
sometimes had more than a million people playing together in the same gaming world.
Characteristics which make super computers different
from ordinary computer?
Super computers has a big differences from ordinary computers like high speed and it is the
most high speed performance as of today and also capable of manipulating massive amount
of data in a short time.
They are much more faster
Generally used for scientific calculations
Use much more power
Give off more heat
Much more expensive
Usage
Supercomputers play an important role in the field ofcomputational science,and are used for
a wide range of computationally intensive tasks in various fields, includingquantum
mechanics,weather forecasting,climate research,oil and gas exploration,molecular
modeling (computing the structures and properties of chemical compounds,
biologicalmacromolecules, polymers, and crystals), and physical simulations (such as
simulations of the early moments of the universe, airplane and spacecraft aerodynamics, the
detonation ofnuclear weapons,andnuclear fusion). Throughout their history, they have been
essential in the field ofcryptanalysis.

Hardware and Architecture
While the supercomputers of the 1970s used only a fewprocessors,in the 1990s, machines
with thousands of processors began to appear and by the end of the 20th century, massivelyparallel supercomputers with tens of thousands of "off-the-shelf" processors were the norm.
Supercomputers of the 21st century can use over 100,000 processors (some beinggraphic
units)connected by fast connections.
Systems with a massive number of processors generally take one of two paths: in one
approach, known asgrid computing,the processing power of a large number of computers in
distributed, diverse administrative domains, is opportunistically used whenever a computer is
available. In another approach, a large number of processors are used in close proximity toeach other, e.g. in acomputer cluster. In such a centralizedmassively parallel system the
speed and flexibility of the interconnect becomes very important and modern supercomputers
have used various approaches ranging from enhancedInfiniband systems to three-
dimensionaltorus interconnects.The use ofmulti-core processors combined with
centralization is an emerging direction, e.g. as in theCyclops64system.

Operating system
Since the end of the 20th century,supercomputer operating systems have undergone major
transformations, as sea changes have taken place insupercomputer architecture.While early
operating systems were custom tailored to each supercomputer to gain speed, the trend has
been to move away from in-house operating systems to the adaptation of generic software
such as Linux.Given that modernmassively parallel supercomputers typically separate
computations from other services by using multiple types ofnodes,they usually run different
operating systems on different nodes, e.g. using a small and efficient lightweight kernel such
asCNK orCNL on compute nodes, but a larger system such as aLinux-derivative on server
andI/O nodes.
While in a traditional multi-user computer systemjob scheduling is in effect
ataskingproblem for processing and peripheral resources, in a massively parallel system, the
job management system needs to manage the allocation of both computational and
communication resources, as well as gracefully dealing with inevitable hardware failures
when tens of thousands of processors are present.
Although most modern supercomputers use theLinux operating system, each manufacturer
has made its own specific changes to the Linux-derivative they use, and no industry standard
exists, partly due to the fact that the differences in hardware architectures require changes to
optimize the operating system to each hardware design.
Software tools and message passing
The parallel architectures of supercomputers often dictate the use of special programming
techniques to exploit their speed. Software tools for distributed processing include
standardAPIs such asMPI andPVM,VTL, andopen source-based software solutions such
asBeowulf.In the most common scenario, environments such asPVM andMPI for loosely connected
clusters andOpenMP for tightly coordinated shared memory machines are used. Significant
effort is required to optimize an algorithm for the interconnect characteristics of the machine
it will be run on; the aim is to prevent any of the CPUs from wasting time waiting on data
from other nodes.GPGPUs have hundreds of processor cores and are programmed using
programming models such asCUDA.Moreover, it is quite difficult to debug and test parallel
programs.Special techniques need to be used for testing and debugging such applications

Performance metrics
Top supercomputer speeds:logscalespeedover 60 years
In general, the speed of supercomputers is measured andbenchmarked in "FLOPS"(Floating
Point Operations Per Second), and not in terms ofMIPS,i.e. as "instructions per second", as
is the case with general purpose computers.[69]These measurements are commonly used with
anSI prefix such astera-, combined into the shorthand "TFLOPS" (1012FLOPS,
pronounced teraflops), orpeta-, combined into the shorthand "PFLOPS" (1015FLOPS,
pronounced petaflops.) "Petascale"supercomputers can process one quadrillion (1015) (1000
trillion) FLOPS.Exascale is computing performance in the exaflops range. An exaflop is one
quintillion (1018) FLOPS (one million teraflops).

2010s Molecular Dynamics Simulation (Tianhe-1A)
The IBMBlue Gene/P computer has been used to simulate a number of artificial neurons
equivalent to approximately one percent of a human cerebral cortex, containing 1.6 billion
neurons with approximately 9 trillion connections. The same research group also succeeded
in using a supercomputer to simulate a number of artificial neurons equivalent to the entiretyof a rat's brain.
Modern-day weather forecasting also relies on supercomputers. TheNational Oceanic and
Atmospheric Administration uses supercomputers to crunch hundreds of millions of
observations to help make weather forecasts more accurate.
In 2011, the challenges and difficulties in pushing the envelope in supercomputing were
underscored byIBM's abandonment of theBlue Waterspetascale project.

Supercomputers Operating System
Early sys tems
The firstCray-1(sample shown with internals) was delivered to the customer without an operating system. [8]
TheCDC 6600,generally considered the first supercomputer in the world, ran theChippewa
Operating System, which was then deployed on various otherCDC 6000
series computers. The Chippewa was a rather simple job control oriented system derived
from the earlierCDC 3000,but it influenced the laterKRONOS andSCOPE systems.
The firstCray 1 was delivered to the Los Alamos Lab without an operating system, or any
other software. Los Alamos developed not only the application software for it, but also the
operating system. The main timesharing system for the Cray 1, the Cray Time Sharing
System (CTSS), was then developed at the Livermore Labs as a direct descendant of
theLivermore Time Sharing System (LTSS) for the CDC 6600 operating system from twenty
years earlier.
The rising software costs in developing a supercomputer soon became dominant, as
evidenced by the fact that in the 1980s the cost for software development at Cray came to
equal what they spent on hardware. That trend was partly responsible for a move away from
the in-houseCray Operating System toUNICOS system based onUnix. In 1985, theCray
2 was the first system to ship with the UNICOS operating system.
Around the same time, theEOS operating system was developed byETA Systems for use in
theirETA10 supercomputers. Written inCybil, a Pascal-like language fromControl Data
Corporation,EOS highlighted the stability problems in developing stable operating systems
for supercomputers and eventually a Unix-like system was offered on the same machine. The
lessons learned from the development of ETA system software included the high level of risk

associated with the development of a new supercomputer operating system, and the
advantages of using Unix with its large existing base of system software libraries.
By the middle 1990s, despite the existing investment in older operating systems, the trend
was towards the use of Unix-based systems, which also facilitated the use ofinteractive userinterfacesforscientific computing across multiple platforms. The move towards a 'commodity
OS' was not without its opponents who cited the fast pace and focus of Linux development as
a major obstacle towards adoption. As one author wrote "Linux will likely catch up, but we
have large-scale systems now". Nevertheless, that trend continued to build momentum and by
2005, virtually all supercomputers used some UNIX like OS. These variants of UNIX
includedAIX from IBM, the open sourceLinux system, and other adaptations such
asUNICOS from Cray. By the end of the 20th century, Linux was estimated to command thehighest share of the supercomputing pie.
Modern approaches
TheBlue Gene/P supercomputer atArgonne National Lab
The IBMBlue Gene supercomputer uses theCNK operating system on the compute nodes,
but uses a modifiedLinux-based kernel calledINK (for I/O Node Kernel) on the I/O
nodes. CNK is alightweight kernel that runs on each node and supports a single application
running for a single user on that node. For the sake of efficient operation, the design of CNK
was kept simple and minimal, with physical memory being statically mapped and the CNK
neither needing nor providing scheduling or context switching. CNK does not even
implementfile I/O on the compute node, but delegates that to dedicated I/O nodes. However,
given that on the Blue Gene multiple compute nodes share a single I/O node, the I/O node
operating system does require multi-tasking, hence the selection of the Linux-based operating
system.

massively parallel system, the job management system needs to manage the allocation of both
computational and communication resources. The need to tune task scheduling and tune the
operating system in different configurations of a supercomputer is essential. A typical parallel
job scheduler has amaster scheduler which instructs a number of slave schedulers to launch,
monitor and controlparallel jobs,and periodically receives reports from them about the status
of job progress.
Some, but not all supercomputer schedulers attempt to maintain locality of job execution.
ThePBS Pro scheduler used on theCray XT3 andCray XT4 systems does not attempt to
optimize locality on its three dimensionaltorus interconnect, but simply uses the firstavailable processor. On the other hand, IBM's scheduler on the Blue Gene supercomputers
aims to exploit locality and minimize network contention by assigning tasks from the same
application to one or more midplanes of an 8x8x8 node group. TheSLURM scheduler uses a
best fit algorithm, and performsHilbert curve scheduling in order to optimize locality of task
assignments. A number of modern supercomputers such as theTianhe-I use the SLURM job
scheduler which arbitrates contention for resources across the system. SLURM isopen
source,Linux-based, is quite scalable, and can manage thousands of nodes in a computer
cluster with a sustained throughput of over 100,000 jobs per hour.

Applications of super computers
Recreating the Big Bang
It takes big computers to look into the biggest question of all: What is the origin of the
universe?
The "Big Bang," or the initial expansion of all energy and matter in the universe, happened
more than 13 billion years ago in trillion-degree Celsius temperatures, but supercomputer
simulations make it possible to observe what went on during the universe's birth. Researchers
at the Texas Advanced Computing Centre (TACC) at the University of Texas in Austin have
also used supercomputers to simulate the formation of the first galaxy, while scientists at
NASAs Ames Research Centre in Mountain View, Calif., have simulated the creation of
stars from cosmic dust and gas.
Supercomputer simulations also make it possible for physicists to answer questions about the
unseen universe of today. Invisible dark matter makes up about 25 percent of the universe,
anddark energy makes up more than 70 percent, but physicists know little about either.
Using powerful supercomputers like IBM's Roadrunner at Los Alamos National Laboratory,researchers can run models that require upward of a thousand trillion calculations per second,
allowing for the most realistic models of these cosmic mysteries yet.
Understanding earthquakes
Other supercomputer simulations hit closer to home. By modeling the three-dimensional
structure of the Earth, researchers can predict howearthquake waves will travel both locally
and globally. It's a problem that seemed intractable two decades ago, says Princeton

geophysicist Jeroen Tromp. But by using supercomputers, scientists can solve very complex
equations that mirror real life.
"We can basically say, if this is your best model of what the earth looks like in a 3-D sense,
this is what the waves look like," Tromp said.
By comparing any remaining differences between simulations and real data, Tromp and his
team are perfecting their images of the earth's interior. The resulting techniques can be used
to map the subsurface for oil exploration or carbon sequestration, and can help researchers
understand the processes occurring deep in the Earth's mantle and core.
Folding Proteins
In 1999, IBM announced plans to build the fastest supercomputer the world had ever seen.
The first challenge for this technological marvel, dubbed "Blue Gene"?
Unravelling the mysteries of folding. Proteinsare made of long strands of amino acids folded
into complex three-dimensional shapes. Their function is driven by their form. When a
protein misfolds, there can be serious consequences, including disorders like cystic fibrosis,
Mad Cow disease and Alzheimer's disease. Finding out how proteins foldand how folding
can go wrongcould be the first step in curing these diseases.
Blue Gene isn't the only supercomputer to work on this problem, which requires massive
amounts of power to simulate mere microseconds of folding time. Using simulations,
researchers have uncovered the folding strategies of several proteins, including one found in
the lining of the mammalian gut. Meanwhile, the Blue Gene project has expanded. As of
November 2009, a Blue Gene system in Germany is ranked as the fourth-most powerful
supercomputer in the world, with a maximum processing speed of a thousand trillion
calculations per second.

Mapping the blood stream
Think you have a pretty good idea of how your blood flows? Think again. The total length of
all of the veins, arteries and capillaries in the human body is between 60,000 and 100,000
miles. To map blood flow through this complex system in real time, Brown University
professor of applied mathematics George Karniadakis works with multiple laboratories and
multiple computer clusters.
In a 2009 paper in the journal Philosophical Transactions of the Royal Society, Karniadakas
and his team describe the flow of blood through thebrain of a typical person compared with
blood flow in the brain of a person with hydrocephalus, a condition in which cranial fluid
builds up inside the skull. The results could help researchers better understand strokes,
traumatic brain injury and other vascular brain diseases, the authors write.
Modeling swine flu
Potential pandemics like the H1N1 swine flu require a fast response on two fronts: First,
researchers have to figure out how the virus is spreading. Second, they have to find drugs tostop it.
Supercomputers can help with both. During the recent H1N1 outbreak, researchers at
Virginia Polytechnic Institute and State University in Blacksburg, Va., used an advanced
model of disease spread called EpiSimdemics to predict the transmission of the flu. The
program, which is designed to model populations up to 300 million strong, was used by the
U.S. Department of Defense during the outbreak, according to a May 2009 report in IEEE
Spectrum magazine.

Meanwhile, researchers at the University of Illinois at Urbana-Champaign and the University
of Utah were using supercomputers to peer into the virus itself. Using the Ranger
supercomputer at the TACC in Austin, Texas, the scientists unraveled the structure of swine
flu. They figured out how drugs would bind to the virus and simulated the mutations that
might lead to drug resistance. The results showed that the virus was not yet resistant, but
would be soon, according to a report by the TeraGrid computing resources center. Such
simulations can help doctors prescribe drugs that won't promote resistance.
Testing nuclear weapons
Since 1992, the United States has banned the testing ofnuclear weapons.But that doesn't
mean the nuclear arsenal is out of date.
The Stockpile Stewardship program uses non-nuclear lab tests and, yes, computer simulations
to ensure that the country's cache of nuclear weapons are functional and safe. In 2012, IBM
plans to unveil a new supercomputer, Sequoia, at Lawrence Livermore National Laboratory
in California. According to IBM, Sequoia will be a 20 petaflop machine, meaning it will be
capable of performing twenty thousand trillion calculations each second. Sequoia's primedirective is to create better simulations of nuclear explosions and to do away with real-world.

Forecasting hurricanes
With Hurricane Ike bearing down on the Gulf Coast in 2008, forecasters turned to Ranger for
clues about the storm's path. This supercomputer, with its cowboy moniker and 579 trillion
calculations per second processing power, resides at the TACC in Austin, Texas. Using data
directly from National Oceanographic and Atmospheric Agency airplanes, Ranger calculated
likely paths for the storm. According to a TACC report, Ranger improved the five-day
hurricane forecast by 15 percent.
Simulations are also useful after a storm. When Hurricane Rita hit Texas in 2005, Los
Alamos National Laboratory in New Mexico lent manpower and computer power to model
vulnerable electrical lines and power stations, helping officials make decisions about
evacuation, power shutoff and repairs.
Predicting climate change
The challenge of predicting global climate is immense. There are hundreds of variables, from
the reflectivity of the earth's surface (high for icy spots, low for dark forests) to the vagaries
of ocean currents. Dealing with these variables requires supercomputing capabilities.Computer power is so coveted by climate scientists that the U.S. Department of Energy gives
out access to its most powerful machines as a prize.
The resulting simulations both map out the past and look into the future. Models of the
ancient past can be matched with fossil data to check for reliability, making future predictions
stronger. New variables, such as the effect of cloud cover on climate, can be explored. One
model, created in 2008 at Brookhaven National Laboratory in New York, mapped the aerosol
particles and turbulence of clouds to a resolution of 30 square feet. These maps will have to

become much more detailed before researchers truly understand how clouds affect climate
over time.
Building brains
So how do supercomputers stack up tohuman? Well, they're really good at computation: It
would take 120 billion people with 120 billion calculators 50 years to do what the Sequoia
supercomputer will be able to do in a day. But when it comes to the brain's ability to process
information in parallel by doing many calculations simultaneously, even supercomputers lag
behind. Dawn, a supercomputer at Lawrence Livermore National Laboratory, can simulate
the brain power of a catbut 100 to 1,000 times slower than a real cat brain.
Nonetheless, supercomputers are useful for modeling the nervous system. In 2006,
researchers at the colePolytechniqueFdrale de Lausanne in Switzerland successfully
simulated a 10,000-neuron chunk of a rat brain called a neocortical unit. With enough of
these units, the scientists on this so-called "Blue Brain" project hope to eventually build a
complete model of the human brain.
The brain would not be an artificial intelligence system, but rather a working neural circuit
that researchers could use to understand brain function and test virtual psychiatric treatments.But Blue Brain could be even better than artificial intelligence, lead researcher Henry
Markram told The Guardian newspaper in 2007: "If we build it right, it should speak."

How super computer is different from other computers??
Mainframe computers were introduced in 1975. A mainframe computer is a large computer in
term of price, power and speed. It is more powerful than minicomputer. Mainframe computer
can serve up to 50,000 users simultaneously. Its price is $5000 to $5 million. These
computers can store large amount of data, information and instructions. The users access a
mainframe computer through terminal or personal computer.A typical mainframe computer
can execute 16 million instructions per second. Qualified operators and programmers are
required to use these computers. Mainframe computers can accept all types of high-level
languages. Different types of peripheral devices can be attached with mainframe computer.
Examples:
1- IBM4381
2- NEC 610
3- DEC 10 etc.
Super Computer: Super computer were introduced in 1980. Super computer is the biggest in
size and the most expensive in price than any other computers. It is the most sophisticated,
complex and advanced computer. It has very large storage capacity. It can process trillions of
instructions in one second. Its price is $500000 to $350 million. Super computer use high
speed facilities such as satellite for online processing.
A supercomputer can handle high amounts of scientific computation. It is maintained in a
special room. It is 50000 times faster than that of microcomputers, which are very common
nowadays. The cost that is associated with a supercomputer is roughly $20 million. Due to its
high cost it is not used for domestic or office level of work.
Examples:
1- CRAY-XP
2- ETA-10 etc.

It is used in areas such as defence, weaponry systems, weather forecasting or scientific
research. It was first used for defence purposes and was used to keep the record information
of war weapons and its allied products.
For example George and David Chudnovsky broke the world record for PI calculation by
using two supercomputers to calculate PI to 480 million decimal places (PI is a commonly
used mathematical constant that is based on the relationship of a circle's circumference to its
diameter). From there onwards the value of PI became popular for geographically related
calculations. In the next few years, more and more large industries will start using
supercomputers such as the parallel computer, which will have hundreds or even thousands of
processors.
Mainframe computers are used in large scale organization whereas super computers are
considered to be fast with regardless of its size.Mainframes are generally called as an
operating system whereas super computers are a mini computers.
A MAINFRAME is one form of a computer system that is generally more powerful than
other typical mini systems. They r used in large organizations 4 large scale jobs& also
mainframes themselves may vary widely cost capability.
The kind traditionally used as the main record-keeper and data processor for large businesses
and government facilities. But Super-computer" is a term used for very fast computers,
regardless of their physical size. It used to be that a computer that could perform more than
one gigaflop (one billion operations per second) was considered to be a supercomputer. Now,
most high-end personal computers operate at that speed The most largest ,fastest the most
expensive computers in the world is SUPER COMPUTER. They are used for Bio-Medical
Research, Weather Forecasting,and Chemical Analysis in Laboratory etc.NEC'sEarth
Simulator in Japan is now world's fastest computer.

Supercomputing in India
India'ssupercomputerprogram was started in late 1980s becauseCraysupercomputers were
denied for import due to an arms embargo imposed on India, as it was a dual use technologyand could be used for developingnuclear weapons.
PARAM 8000 is considered India's firstsupercomputer. It was indigenously built in 1990
by Centre for Development of Advanced Computing and was replicated and installed at
ICAD Moscow in 1991 under Russian collaboration.

PARAM SERIES
After being deniedCraysupercomputers as a result of a technologyembargo,India started a
program to develop indigenous supercomputers and supercomputing technologies.
Supercomputers were considered a double edged weapon capable of assisting in the
development ofnuclear weapons.[5]For the purpose of achieving self-sufficiency in the field,
theCentre for Development of Advanced Computing (C-DAC) was set up in 1988 by the
then Department of Electronics with Dr.Vijay Bhatkar as its Director. The project was given
an initial run of 3 years and an initial funding of 300,000,000. Because the same amount of
money and time was usually expended to purchase a supercomputer from the US. In 1990,
aprototype was produced and wasbenchmarked at the 1990 Zurich Supercomputing Show. It
surpassed most other systems, placing India second after US.
The final result of the effort was the PARAM 8000, which was installed in 1991. It is
considered India's first supercomputer.
PARAM 8000
Unveiled in 1991, PARAM 8000 usedInmos T800transputers.Transputers were a fairly new
and innovativemicroprocessor architecture designed forparallel processing at the time. It
was a distributedMIMD architecture with a reconfigurable interconnection network. It had
64CPUs.
PARAM 8600
PARAM 8600 was an improvement over PARAM 8000. It was a 256 CPU computer. For
every four Inmos T800, it employed anIntel i860 coprocessor. The result was over
5GFLOPS at peak forvector processing.Several of these models were exported.
PARAM 9900/SS
PARAM 9900/SS was designed to be aMPP system. It used theSuperSPARC IIprocessor.
The design was changed to be modular so that newer processors could be easily
accommodated. Typically, it used 32-40 processors. But, it could be scaled up to 200 CPUs
using theclose network topology.PARAM 9900/USwas theUltraSPARC variant
and PARAM 9900/AAwas the DEC variant.

PARAM 10000
In 1998, the PARAM 10000 was unveiled. PARAM 10000 used several independent nodes,
each based on theSun Enterprise 250 server and each such server contained two
400MhzUltraSPARC IIprocessors. The base configuration had three compute nodes and aserver node. The peak speed of this base system was 6.4GFLOPS.A typical system would
contain 160CPUs and be capable of 100GFLOPS.But; it was easily scalable to
theTFLOP range.
PARAM Padma
PARAM Padma (PadmameansLotusinSanskrit)was introduced in April 2003.It had a peak
speed of 1024 GFLOPS (about 1 TFLOP) and peak storage of 1 TB. It used
248IBMPower4CPUs of 1 GHz each. Theoperating system was IBM AIX 5.1L. It used
PARAMnet II as its primary interconnects. It was the first Indian supercomputer to break the
1 TFLOP barriers.
PARAM Yuva
PARAM Yuva (Yuvameans YouthinSanskrit) was unveiled in November 2008. It has a
maximum sustainable speed (Rmax) of 38.1 TFLOPS and a peak speed (Rpeak) of 54
TFLOPS.[10]There are 4608 cores in it, based onIntel 73XX of 2.9 GHz each. It has a storagecapacity of 25 TB up to 200 TB. It uses PARAMnet 3 as its primary interconnects.
ParamYuva II
ParamYuva II was made by Centre for Development of Advanced Computing in a period of
three months, at a cost of 16 crore (US$2 million), and was unveiled on 8 February 2013. It
performs at a peak of 524 teraflops and consumes 35% less energy as compared to
ParamYuva. It delivers sustained performance of 360.8 teraflops on the community standard
Linpack benchmark, and would have been ranked 62 in the November 2012 ranking list of
Top500. In terms of power efficiency, it would have been ranked 33rd in the November 2012
List of Top Green500 supercomputers of the world. It is the first Indian supercomputer
achieving more than 500 teraflops.
