&gt;The ratio can now be as much as 1:100, so a supercomputer is forced to spend the vast majority of its time moving data to and from memory.  This is spurring the adoption of data-tiering hardware and software that try to maximize CPU effectiveness by storing frequently accessed data in high-speed tiers such as solid-state drive<p>Err... this isn&#x27;t new, wouldn&#x27;t the high speed tiers be processor registers and cache and we&#x27;ve been doing this for over 30 years?
