Show answer & explanation

Correct answer: A. Sun-way TaihuLight

Explanation

At the time this paper was set (November 2017) China's Sunway TaihuLight topped the TOP500 list at about 93 petaflops on the LINPACK benchmark, well ahead of the other three machines. Piz Daint (Switzerland) was second at roughly 19.6 petaflops, Titan (Oak Ridge) about 17.6 petaflops and Sequoia (Lawrence Livermore) about 17.2 petaflops. Note that this is a general computing-awareness item rather than a software engineering one, and its correctness is tied to the 2017 ranking.
