  • Curious Droid presents the top 10 fastest computers in the world how do they

  • 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

  • thanks for watching and I hope you enjoyed the video if you did then don't
