10 fastest supercomputers in the world 2018

    Two months ago, in June, the Top500 list was published. Top500 is a project for compiling ratings and descriptions of the 500 most powerful socially known computing systems in the world. The current list of supercomputers is published twice a year (June / November). The project is just celebrating its anniversary (25 years) and, which is good news, the list has been updated compared to the previous ones, it includes 133 new systems, and the first places are occupied by new favorites.

    It seems that they accumulated all the world's digatal power. Meet the world's top 10 fastest supercomputers in 2018. The entire rating of the link .

    1. Summit - IBM (USA)

    What we observe:

    • The USA is again in the first place in the Top500 rating (there was no American system in the top since 2012)
    • China still leads in the number of supercomputers in the Top500 list.
    • 202 supersystems belong to China, 104 - the USA, 36 - to Japan, 22 - Great Britain, 21 - Germany, 18 - France.
