I'm of mixed feelings about this. I'm in HPC now, and the thing I'm interested in is RIKEN's post-K supercomputer (http://www.aics.riken.jp/fs2020p/en/ http://www.aics.riken.jp/fs2020p/en/). Fujitsu is building it, and they're going to be producing the CPUs that will be going into post-K, just as they did for K. But, where the K supercomputer used SPARC, this new one is going to use ARM (https://www.top500.org/news/fujitsu-switches-horses-for-post-k-supercomputer-will-ride-arm-into-exascale/ https://www.top500.org/news/fujitsu-switches-horses-for-post...). Also, Fujitsu are working with ARM to develop HPC-specific architecture extensions to the ARMv8 spec. Plus, as Applied Micro has been acquired by MACOM, I wonder how that's going to settle out. So, I'm waiting to see what Fujitsu comes up with. The Post-K supercomputer will be a very good proving ground.
