Cray is creating the world's first production-ready, Arm-based supercomputer with the addition of Cavium ThunderX2 processors, based on 64-bit Armv8-A architecture, to the Cray XC50 supercomputer.

By David Manners, ElectronicsWeekly, Nov. 14, 2017 – 

Cray customers will have a complete Arm-based supercomputer that features a full software environment, including the Cray Linux Environment, the Cray Programming Environment, and Arm-optimized compilers, libraries, and tools for running today's supercomputing workloads.

Cray enhanced its compiler and programming environment to achieve more performance out of the Cavium ThunderX2 processors. In a head-to-head comparison of 135 standard HPC benchmarks, Cray's compiler showed performance advantages in two-thirds of the benchmarks, and showed significant (more than 20%) performance advantage in one-third of the tests, versus other public domain Armv8 compilers from LLVM and GNU.
