Cray ARMs Highest End Supercomputer with ThunderX2

Beats Intel Broadwell and Skylake in many memory-bound codes and surprisingly enough it can compensate with core count and clocks for its meager SIMD units even when running strongly instruction and cache-bound codes like GROMACS.

Among the many questions remaining consumption/efficiency is certainly among the top and which accelerators will the ThunderX2 platform be paired with first? NVIDIA does not have (officially) an Aarch64 driver. AMD's OSS ROCm stack however will soon be released for Aarch64 [1].
