This article is well worth a read, on European Exascale projects https://www.theregister.co.uk/2018/07/17/europes_exascale_supercomputer_chips/
The automotive market seems to have got mixed in there also! The main thrust dual ARM based and RISC-V Also I like the plexiglass air shroud pictured at Barcelona. I saw something similar at the HPE centre in Grenoble. Damn good idea.
