Two weeks ago we wrote about Frontier, a supercomputer at the US Department of Energy's Oak Ridge National Laboratory, arguably the first to have achieved exascale (the ability to perform more than a quintillion calculations per second). Europe too has ambitions in this field: The European High Performance Computing Joint Undertaking announced this week that it has selected the J¨¹lich Supercomputing Centre in Germany to host the continent's first exascale supercomputer. The €500 million required to build the machine is provided half by the Joint Undertaking -an EU initiative dedicated to developing world-leading supercomputing infrastructure -and half by a coalition of the German Federal Ministry of Education and Research, the Ministry of Culture and Science, and the State of North Rhine-Westphalia.
