Who is Afraid of I/O?
Michela Taufer · 2016
Clear trends in the past and current petascale systems (i.e., Jaguar and Titan) and the new generation of systems that will transition us toward exascale (i.e., Aurora and Summit) outline how concurrency and peak performance are growing dramatically, however, I/O bandwidth remains stagnant. Next-generation systems are expected to deliver 7 to 10 times higher peak floating-point performance with only 1 to 2 times higher PFS bandwidth compared to the current generation.
