compare to a PC or iPad pro if you need to model things like the world's weather,

nuclear reactions, molecular dynamics or simulate the first few seconds after the

Big Bang you're gonna need some pretty serious computing power but just how

much more powerful other top 10 supercomputers compared to the PC on

your desktop or an iPad Pro for example in this video we'll see just how

powerful supercomputers have become but first we need to know how do you measure

a computer's performance there are lots of ways to do this but the most common

high-performance systems and the simplest to understand is to measure how

many calculations per second they're capable of the unit of measurement is

called the flop or floating point operation a flop is a calculation that

would be even adding subtracting multiplying or dividing two numbers with

decimal points in them for example 10.545 multiplied by 6.387 would be

a single flop modern computers can do with billions of times a second at the

time of making this video in February 2016 the latest iPad pro

with the A9x dual core CPU is capable of around about 1.5 gigaFLOPS that's one and a

half thousand million flops per second a typical $1,000 PC with a single Intel

5820 6 core CPU is capable of around 100 gigaFLOPS

66 times more than an iPad Pro you can measure the performance of your own

Intel based PC or Mac or mobile device with the same type of Linpack software

as a used to benchmark supercomputers just look for the link in the

description of this video because supercomputers are so much more powerful

they are measured in PetaFLOPS one PetaFLOP is equal to 1,000 teraFLOPs

and one teraFLOP is equal to 1000 GigaFLOPs and remember our PC was 100

gigaFLOPS and the iPad Pro 1.5 gigaFLOPs. A petaFLOP is equal to

about 1 million billion calculations per second one estimate suggests that it

would take a human about 32 million years to complete the same task now we

know one everyday computing device that you or I own is capable of let's see how it

compares to the top 10 supercomputers in the world. All the figures given were

correct as of November 2015 and gathered from the top500 list of supercomputers

at number ten we have the Stampede supercomputer the Texas Advanced

Computing Center at the University of Texas in United States this

supercomputer is made by Dell and has a maximum Linpack performance of 5.1

petaFLOPs that's equivalent of 51,000 of our $1000 PC's or 3.4 million iPad pros

it has 464,462 processing cores and 192Tb

of RAM and consumes approximately 4.5 megawatts of power at

maximum performance at number nine we have been Shaheen 2 at the King Abdullah

University of Science and Technology in saudi arabia this supercomputer is made

by Cray and has a maximum Linpack performance of 5.5 petaFLOPs that's

equivalent of 55,000 of our PCs or 3.66 million iPad pros it costs approximately

$51M to buy and install it has 196,608 processing cores and 790

terabytes of RAM

consumes a maximum power of 2.8 megawatts at number eight is the

Hazel Hen at the HLRS in Stuttgart Germany this is another super computer

made by Cray Inc and it has a maximum Linpack performance of 5.6 petaFLOPs

and is the fastest supercomputer in the European Union that's equipped to

56,000 of our PC's or 3.73 million iPad pros it has 185,088

processing cores and consumes a maximum of 3.2 megawatts of power at number

seven we have the Piz Daint at the Swiss National Supercomputing Center at Lugano

Switzerland the Piz Daint named after a nearby mountain is yet another

Cray built supercomputer has a maximum Linpack performance of 6.2 petaFLOPs thats

equivalence of 62,000 of our PCs or 4.13 million iPad pros it has 115,984

processing cores and 169Tb

of RAM and consumes a maximum of 2.3 megawatts of power at

number six is the trinity at the Los Alamos National Laboratory New Mexico

United States yes this is yet another Cray supercomputer and is a maximum Linpack

performance of 8.1 petaFLOPs

81,000 PCs or 5.4 million iPad pros it has 301,056 processing cores and

cost approximately $174M. At number

five we have the Mira Bluegene/Q at the US Department of Energy Argonne

National Laboratory Illinois United States this supercomputer was built by

IBM and has a maximum Linpack performance of 8.5 petaFLOPs that's the equivalent of

85,000 of our PCs or 5.66 million iPad pro's it has 780,432 processing

cores 768 terabytes of RAM and consumes a maximum of 3.9 megawatts

power no cost has been released by IBM but it was believed to have been around

$50M at number four is the K computer at the RIKEN advanced

Institute for computational science at Kobe Japan built by Fujitsu the K supercomputer

has a maximum Linpack performance of 10.5 petaFLOPs that

the equivalent of 105,000 of our PC's or 7 million iPad Pro's

it has 705,024 processing

cores and 1,410 terabytes of RAM and consumes a maximum of 12 megawatts

of power to give you an idea of a the perforemance of this machine simulation of

the human heart which had taken two years was accomplishing just one day on

the K computer at number three is the Sequoia Bluegene/Q at the Lawrence

Livermore National Laboratory California United States the number three on the

top 10 list is built by IBM and has a maximum Linpack performace of 17.1 petaFLOPs

that's equivalent of 171,000 of our PC's or 11.4

million iPad pros it has 1,572,864

processing cores 1,572 terabytes of RAM and consumes

a maximum power of seven point eight mega watts

the primary use of a Sequoia is for nuclear weapons simulation but it would

also be used to study of the human genome, climate change and astronomy to

name but a few at number two is the Titan

Oak Ridge National Laboratory Tennessee United States another Cray built

supercomputer is at number two on the list and has a maximum Linpack

performance of 17.5 petaFLOPs that the equivalent of 175,000

thousand of our PCs

11.6 million iPad Pro's it has 560,640

processing cores 710 terabytes of RAM and consumes a

maximum of 7.1 mega watts power at the number one slot on the top 10 list of

the world's most powerful supercomputers is the Tianhe-2 or Milky Way 2 have a

national Supercomputer Center at Guangzhou City Guangdong Province China

this was built by the Chinese national university of defense technology and

has a maximum Linpack performance of 33.8 petaFLOPs thats the equivalent of 338,000

our PCs or 22.53 mIllion iPad Pro's it has 3,120,000

processing cores and 1024 terabytes

of RAM and consumed a maximum power of 17.8 megawatts the Tianhe-2 has been a

top supercomputer for the past three years running now in the top 500 list

which comes out twice a year so where do we go from here

well if anyone can figure out how to build a real quantum computer IBM have

previously stated that if one could be made with just 50 quantum bits or qubits

that could detect both types of errors and scale to large systems no

combination of today's top 500 supercomputers could successfully

outperform it until then we'll look forward to the first 1,000 petaflop or

1 exaFLOP machine in hopefully around 2025
