SVE2 is **Silicon** Scalable, not **Programmer** Scalable: the distinction is profoundly -important (already causing problems). +important (already +[causing problems](https://gist.github.com/zingaburga/805669eb891c820bd220418ee3f0d6bd#file-sve2-md) ). For Predicated SIMD, Programmers must emulate Cray-style scaling through explicit predicate masking, which increases instruction count in hot-loops.
