This weekend I was reading this paper on programming the Cerebras wafer scale engine, https://arxiv.org/html/2405.07898v1 . Data movement is the expensive part of computing, and some algorithms like stencils only require nearest neighbor data movement per cycle. Cerebras wafers have very low energy transfer between neighboring processing elements on the same wafer, so they come up with a language called Tungsten that focuses on this exchange primitive in the kernel programming model. I thought the challenge of programming 100,000s of cores using a mesh would be interesting so I wrote a…

There's also interesting custom-made machines for molecular simulations that don't rely on GPGPUs and are significantly faster, e.g.: - https://arxiv.org/abs/2405.07898 - https://www.psc.edu/resources/anton/
