The first exascale computer in Europe, called JUPITER, should be completed next year, and it may even become the most powerful computer in the world. It will allow experiments and simulations currently only possible on a tiny number of machines in the US and China.
Exascale machines can carry out a billion billion operations per second, an exaflop. Currently, there are – officially – only two supercomputers in the world capable of those sorts of calculations: the Frontier machine at the Oak…
