Power ISA is synonymous with Supercomputing and the early Supercomputers
(ETA-10, ILLIAC-IV, CDC200, Cray) had Vectorisation. It is therefore anomalous
-that Power ISA does not have Scalable Vectors, instead having the legacy
-"PackedSIMD" paradigm. Fortunately this presents
-the opportunity to modernise Power ISA learning from both past ISA features and
-mistakes placing it far above the top of Supercomputing for the next two decades
-and beyond.

**Notes and Observations**:
operations to a runtime-selectable choice of 128-bit, 256-bit, 512-bit or 1024-bit.
3. Massive reductions in instruction count of between 2x and 20x have been demonstrated
with SVP64, which is far beyond anything ever achieved by any *general-purpose*
- ISA Extension added to any ISA in the history of Computing. Normal reductions
- expected are of the order of 5 to 10% being considered a highly worthwhile exercise
- to pursue inclusion.
