Today there is an uncompromising execution and continuous thirst for innovation in technology. The question, “What’s the next advancement or feature we can bring and place before the world?”, keeping the technical experts to be on the wire of inventing or discovering something new. It was processor then, it is machine learning now, and it will be an era of supercomputers or maybe minicomputers.

With calmness and determination, there is a derivation for the ideas and by analyzing each idea, by brainstorming, the tech experts are able to unleash the newest and are giving the best technological experience ever.

Well, it’s the product of the US that brings in new supercomputer beating China’s Sunway TaihuLight supercomputer which was considered as the most powerful one till a few days back.

The US named it as “Summit” and initially, it’s applicable in the fields of cancer research, systems biology, and astrophysics. IBM and Nvidia remained as partners and Oak Ridge National Laboratory (ORNL), Tennessee is where it was developed.

However, as everything has a top chart, supercomputers also ranked accordingly. According to 2017 supercomputer chart, the US owned 143 off top 500 while China owned 202.

It was “Titan” from the US that placed at 5th.


200,000 trillion calculations per second is a millennium speed that this supercomputer operates or we can say it’s 200 petaflops (it executes one thousand trillion trillion floating operations per second).

Whereas, China’s Sunway TaihuLight supercomputer is 93 petaflops.

Supercomputers are embedded with thousands of processors those are designed to carry out intensive tasks in a favorable way. Summit has 4,608 computing servers with more than 10 petabytes of memory.

These special considerations make this supercomputer unique from the rest of the supercomputers. Want to have a look at top 10 supercomputers? Here is the list;
