140 Tonnen Silizium, Plastik und Blech für einen Blick in die Zukunft
Ein bisschen Supercomputer-Porno gefällig? Der britische Wetterdienst Met Office hat sich einen neuen Cray XC40 Supercomputer zugelegt. 140 Tonnen schwer, 16 Petaflops schnell, 123 Millionen Euro teuer. 480.000 CPUs sollen die Zellengröße, also die Auflösung, in der die Wettersimulation läuft, auf 1,5 Kilometer herunter bringen - womit zum Beispiel Stadtteilvorhersagen möglich werden.
Die ganz spannenden Cray-XC40-Spezifikationen findet ihr nach dem Break.
