    When is a computer called a supercomputer?


    Have a query about supercomputers? Looking out for more details here? You can scroll through this page and get information regarding the specifications and the make of a supercomputer and the fastest one in the world and in India.

    Today's world is digital age and everything is governed by computer or smart devices. I want to know what is the meaning of supercomputer? What are the specifications of a computer which makes it go into the category of the supercomputer?
    Which company has the fastest supercomputer as of now and which is India's supercomputer?

    What is Super Computer
    A computer with a high level performance than a general purpose computer is called super computer. These super computers were introduced in 1960. Super computer run by the concept called parallel computing, this parallel processing involves in dividing the tasks into smaller tasks that can be processed in parallel. And the result will be obtained by computing outputs from each processor.

    Super computer consists of an array of processors and GPU's which are stacked together to perform high computational tasks. These processors can perform very fast parallel processing. Super computers are collection of smaller supercomputers spread across large geographical distances. Unlike regular computers, super computers are measured based on how many FLOPS they are capable to perform. FLOPS means floating point operations per second. Where as in general computers we measure performance in GHz.

    Applications of Supercomputers
    These were used in many sectors such as weather forecasting, understanding the creation of universe, making meteorological predictions, aerodynamic modelling, bioinformatics, simulating nuclear missile tests, scientific research, missile simulation etc.

    Super Computers in India
    Here are some of the supercomputers in India:

    1. SahasraT Supercomputer located at SERC Supercomputer Education and Research Centre at Indian Institute of Science, Bangalore.
    2. Aditya Super computer manufatured by IBM located at Indian Institute of Tropical Meteorology, Pune.
    3. TIFR Colour Boson located at Tata Institute of Fundamental Research Facility, Hyderabad.
    4. IIT Delhi HPC located at Indian Institute of Technology, Delhi.
    5. Param Yuva 2 located at Center for Development of Advanced Computing in Pune.

    Supercomputers are mainly used for scientific and engineering applications. These computers will handle very large databases or do a great amount of computation or both. A supercomputer is exceptional in terms of performance.
    The largest, most powerful supercomputers are multiple computers which can perform parallel processing. Normally there are two parallel processing approaches symmetric multiprocessing (SMP) and massively parallel processing (MPP).
    The fastest supercomputer in the world was the Sunway TaihuLight, in the city of Wixu in China as on June 2016. A few specifications of TaihuLight Supercomputer are mentioned as
    40,960 64-bit, RISC processors with 260 cores each.
    Peak performance of 125 petaflops (quadrillion floating point operations per second).
    32GB DDR3 memory per compute node, 1.3 PB memory in total.
    Linux-based Sunway Raise operating system (OS).
    A series of supercomputers designed and assembled by the Centre for Development of Advanced Computing (C-DAC) in Pune, India is known as PARAM. The latest machine in the series is the PARAM ISHAN

    First, let me tell you about the basic difference between computer and supercomputers.

    COMPUTER
    1) A computer is an electronic device, which performs arithmetic and logical operations with a set of instruction given by the user.
    2) A computer is also known as mini or microcomputers and even less expensive.
    3) Computer size range from calculator size to desktop size.
    4) These perform small tasks given by the user they can be referred to a personal computer, Desktop computer, Laptop etc

    SUPERCOMPUTERS
    1) Supercomputers are the type of computers which posses the best processing capacity.
    2) Supercomputers are expensive than other types of computers
    3) Supercomputers normally occupy the size of a room.
    4) Supercomputers are specially designed for Scientific jobs like weather forecasting, artificial intelligence research etc. These are the fastest computers.

    Following hardware components like CPU - Central Processing Unit, an Input device, Output device are the same on both the computers.

    The supercomputer was named by the company "Control Data Corporation - CDC" marketed Cyber series of supercomputers and another company named, "Cray Research Incorporation" marketed the Cray series of supercomputers. India has acquired the CRAY X-MP/14 supercomputer from Cray Research Incorporation.
    Today due to technological advances being made, the different computer models are having the capacity for equal functions. For Eg. a powerful Micro can perform the task of a MINI and so on.

    1. A supercomputer is a computer with a very high level of performance compared to a computer normally used at home and in office.
    2. Presently China has the top two fastest supercomputers in the world. I am afraid I don't the name of the Company which has manufactured these supercomputers.
    3. Supercomputer PARAM 8000 made by C-DAC and launched in July 1991 was the first supercomputer of India.

    Beware! I question everything and everybody.

    The performance level of Supercomputer is very high compared to general purpose computer. Super computer used to solve problems that are too massive for standard computers. First Super computer built by Seymour Cray in 1957. Performance of a supercomputer is measured in floating point operations per second(FLOPS) instead of Million instruction per second(MIPS). Super computer is a computer that performs at or near the currently highest operational rate for computers. It is used to handle large database and for performing high calculations. Super computers are too expensive, too big, Supercomputer do same thing what computer does but supercomputer do more faster, with more data and in a different way. Supercomputer system requires scaled up software that organizes, assigns, stores and processes data in the particular way that makes parallel computing possible.

    Pleiades is also a supercomputer in NASA headquarters. The only difference between normal computers and supercomputers are tabulated below.

    Supercomputers
    The processing unit is faster and the Graphical processing unit are lighting fast to bogged down any system information or resources of the host computers and internet. Take an instance of BitCoins mining machines ASCIs machines. They are also super computers.
    By using the graphical processing unit (GPU) in computer graphics cards and installing super computers hardwares, a bit coin mining machine are able to hash data 100 to 1000 times faster and consumed much less power per unit of work.

    This computer can be used in variety of projects. From scientific research to technology. In short its the deadliest of the computer if we consider it as a weapon.

    Hackers never learns but always wins!
