Hello folks,this is Sushil here am sorry for the delay in the posts as i have exams going on.
Today i am going to talk about supercomputers.Yes as the name suggests these are no less than superheroes.Let me give me introduction to the term supercomputer. Basiacally,the supercomputer are body builders of the computer industry.
A supercomputer is a computer with a high-level computational capacity compared to a general-purpose computer. Performance of a supercomputer is measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS). As of 2015, there are supercomputers which can perform up to quadrillions of FLOPS.
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 June 2016, the fastest supercomputer in the world is the Sunway TaihuLight, in mainland China, with a Linpack benchmark of 93 PFLOPS, exceeding the previous record holder, Tianhe-2, by around 59 PFLOPS. It tops the rankings in the TOP500 supercomputer list. Sunway TaihuLight’s emergence is also notable for its use of indigenous chips, and is the first Chinese computer to enter the TOP500 list without using hardware from the United States. As of June 2016, China, for the first time, had more computers (167) on the TOP500 list than the United States (165). However, U.S. built computers held ten of the top 20 positions.
Now to think about this is that where are these beasts used in the real world and how they program and all sort of things . this will obviously take time to explain the whole working of the supercomputers and hence i am going to divide this topic in two posts . this posts i will give its uses and the areas that are used .
These beasts are generally used for the unimaginable calculations that have to be performed in the real life. according to various industries these are used in the so called space calculations. they help in calculating the trajectories and other various high end calculations which even the calculators cant perform . so obviously these calculations are surely way far ahead of what our minds or even the geniuses can think.
Below are five real-life applications of supercomputers that you never knew about until now.
1. The Bitcoin marketplace
Ever thought of supercomputing as a get-rich-quick strategy? Computer geeks do. It turns out that supercomputing processes are perfect for mining for Bitcoin.
The mining community is now using dedicated mining machines built purely to mitigate Bitcoin hash-rate problems. Supercomputers are so well suited to this that they’re now becoming essential for real financial success in the emerging online currency world.
2. Automobile safety ratings
Supercomputers play a very important role in helping people decide what car to buy. When auto manufacturers subject their vehicles to safety testing, only a fraction of the testing is done in a live, simulated environment with a dummy.
In fact, a large portion of a vehicle’s safety rating is based on complex computer-generated scenarios, where supercomputers crunch equations involving dozens upon dozens of different variables.
These computer-generated scenarios, along with the data taken from the crash tests themselves, are analysed to determine safety ratings.
3. The newspaper
Journalists are finding key sources — in the form of supercomputers. The Associated Press and other major news organisations recently began using software that employs algorithms to spot facts and key trends in data, and describe them in a narrative way – effectively enhancing the journalist’s ability to generate insights for data-centric stories such as earnings reports.
The algorithms can comb through historical data for outlier cases, select appropriate words from a vast thesaurus, and apply what it considers to be the best ones to describe a situation. Voila – a news article is made.
4. Smog control in cities
By running meteorological data through high-power supercomputers, scientists can predict pollution levels in major cities like Beijing.
These processes can help identify the source and dispersal pattern of pollutants across Beijing with a street-level degree of detail days in advance.
Armed with this information, public health officials can warn at-risk individuals and potentially control the pollution’s damaging effect on a community.
The same insights can also help reduce pollution in the future by looking at energy consumption, predicting the effectiveness of alternative energy sources – such as solar and wind – or effectively managing energy production to minimise waste.
Hope you guys love these beasts and dream about computing with these beasts. i will tell you the hardware and software part about this in the next post.
