13.5 Million Core Computers

Having a twin or quad core CPU shouldn’t be so unique lately, and 12 and even 16 core CPUs aren’t that unusual. This Andromeda A supercomputer from Cerebras with 13.5 million cores. The corporate claims it is one of many largest AI supercomputers ever constructed (however not the most important) and might carry out 120 Petaflops of “intensive computing.”

We’re undecided of the methodology, however additionally they declare to have a number of “AI computing” exaflops. The pc has a cloth backplane that may course of 96.8 terabits per second between nodes. In accordance with a submit at Extreme Technology, the core know-how is WSE-2, a 3-plane wafer processor. One aircraft is for communication, one holds 40GB of static RAM, and the maths aircraft has 850,000 impartial cores and three.4 million floating level models.

Knowledge is distributed to the cores and picked up by a financial institution of 64-core AMD EPYC 3 processors. Andromeda is optimized to deal with sparse matrix calculations. The corporate claims that efficiency scales “virtually linearly”. So if you double the variety of cores used, you get roughly half of the entire runtime.

The machine is appropriate for distant use and value about $35 million to construct. Additionally it is not free to run, because it makes use of 500 kW at peak working occasions. Excessive Tech states that the Frontier laptop at Oak Ridge Nationwide Labs is each bigger and extra exact, however prices $600 million, so that you’d count on it to be extra succesful.

Most homebrew “supercomputers” we have seen are extra learning how to work with sets quite than making an attempt to realize that sort of efficiency. In fact when you’ve got a contemporary graphics card OpenCL and CUDA it can allow you to do a few of that as properly, however on a a lot smaller scale.
