The Trillion-Transistor Chip That Just Left a Supercomputer in the Dust:
So, in a recent trial, researchers pitted the chip—which is housed in an all-in-one system about the size of a dorm room mini-fridge called the CS-1—against a supercomputer in a fluid dynamics simulation. Simulating the movement of fluids is a common supercomputer application useful for solving complex problems like weather forecasting and airplane wing design.
The trial was described in a preprint paper written by a team led by Cerebras's Michael James and NETL's Dirk Van Essendelft and presented at the supercomputing conference SC20 this week. The team said the CS-1 completed a simulation of combustion in a power plant roughly 200 times faster than it took the Joule 2.0 supercomputer to do a similar task.
The CS-1 was actually faster-than-real-time. As Cerebrus wrote in a blog post, "It can tell you what is going to happen in the future faster than the laws of physics produce the same result."
The researchers said the CS-1's performance couldn't be matched by any number of CPUs and GPUs. And CEO and cofounder Andrew Feldman told VentureBeat that would be true "no matter how large the supercomputer is." At a point, scaling a supercomputer like Joule no longer produces better results in this kind of problem. That's why Joule's simulation speed peaked at 16,384 cores, a fraction of its total 86,400 cores.

I was at the conference where this was introduced. The consensus among the attendees, all of whom were experts in the field, was that it was yet another attempt at WSI, was an impressive proof-of-concept, and like every other time this has been tried would sink without trace after a year or two. No-one could see where this was going or who would buy it apart from one or two national labs to play with it for awhile.

Sorry... what is a "WSI," and why is this apparently not-a-big-deal? (I'm not as familiar with this field.)
