ARM seems a competitor to Intel in HPC, particularly in the Fujitsu post-K system (whose actual name I forget), but even the existing ThunderX2 systems. Interestingly, Intel people don't necessarily have the information to optimize for Intel CPUs even, and the hardware may not tell you. It's really complicated and messy. An example that's relevant to linear algebra is figuring out whether to use FMA, e.g. https://github.com/jeffhammond/vpu-count https://github.com/jeffhammond/vpu-count
