top 5 supercomputers

Computers have become an important part of our life, we are seeing how computers are changing our world and making our lives easier every day. We have come a long way from world’s very first computer to Quantum computers that’s 1 billion times faster than the first electronic computer and 100 million times faster than a conventional one core PC.

But we’ll be covering only supercomputers, so the question why do we need supercomputers when we have home computers that are capable of doing big calculations? well, home computers are good to do calculations we use on a daily basis but when it comes to scientific researches and calculations home computer are useless.

Supercomputers play a big role in research and development like finding secrets of the universe or solving maths problems like graham’s number.

Top 5 Supercomputers In The World:

5. K Computer:

The K computer – named for the Japanese word “Kei”, meaning 10 quadrillion in simple 1016. K computer comprises 88,128 2.0 GHz eight-core SPARC64 VIIIfx processors contained in 864 cabinets, for a total of 705,024 cores. Each cabinet contains 96 computing nodes. Each computing node contains a single processor and 16 GB of memory.

4. IBM Sequoia:

IBM Sequoia is a petascale Blue Gene/Q supercomputer constructed by IBM for the National Nuclear Security Administration as part of the Advanced Simulation and Computing Program (ASC).  It consists of 96 racks containing 98,304 compute nodes, The compute nodes are 16-core A2 processor chips with 16 GB of DDR3 memory each. Thus, the system contains a total of 96·1024·16 = 1,572,864 processor cores with 1.5 PiB memory.

3. Titan:

Titan is a supercomputer built by Cray at Oak Ridge National Laboratory for use in a variety of science projects. Titan is an upgrade of Jaguar supercomputer. Titan has 18,688 nodes (4 nodes per blade, 24 blades per cabinet), each containing a 16-core AMD Opteron 6274 CPU with 32 GB of DDR3 ECC memory and Nvidia Tesla K20X GPU with 6 GB GDDR5 ECC memory. There is a total of 299,008 processor cores and a total of 693.6 TiB of CPU and GPU RAM.

2. Milky Way-2:

Milky way-2 is a 33.86-petaflopsupercomputer located in National Supercomputer Center in Guangzhou. It was developed by a team of 1,300 scientists and engineers. Milky Way-2 contains 16,000 computer nodes, each comprising two Intel Ivy Bridge Xeon processors and three Xeon Phi coprocessor chips. Milky Way-2 represented the world’s largest installation of Ivy Bridge and Xeon Phi chips, counting a total of 3,120,000 cores. Each of the 16,000 nodes possessed 88 gigabytes of memory.  The total CPU plus coprocessor memory was 1,375 TiB (approximately 1.34 PiB).

1. Sunway TaihuLight:

The Sunway Taihulight is a Chinese supercomputer which, as of November 2016, is ranked number one as the fastest supercomputer in the world. The Sunway TaihuLight uses a total of 40,960 Chinese-designed SW26010 manycore 64-bit RISC processors. Each processor chip contains 256 processing cores and an additional four auxiliary cores for system management (also RISC cores, just more fully featured) for a total of 10,649,600 CPU cores across the entire system.
