Enterprise Datacenter Hardware Assumptions May Be In For a Shakeup (acm.org)

Posted by timothy on from the bottlenecks-shift dept.

For the entire careers of most practicing computer scientists, a fundamental observation has consistently held true: CPUs are significantly more performant and more expensive than I/O devices. The fact that CPUs can process data at extremely high rates, while simultaneously servicing multiple I/O devices, has had a sweeping impact on the design of both hardware and software for systems of all sizes, for pretty much as long as we've been building them. This assumption, however, is in the process of being completely invalidated.

    Look at the I/O towers.
    Every tower is lighting up.

    Never seen the word "performant" until today. Must be an obscure five-dollar word that scientists love to toss around. Meanwhile, I'll stick with cheap performance as my word of choice.
