This is such a novel and strange device. I can imagine it might be useful for a lot of things, but what? The non-Von Neumann architecture (putting compute next to memory) has been tried many times and AFAIK never taken hold. What would you use this for?
Vector search is a great application for this. You can run the HNSW algorithm on the riscV cores local to the memory. Which is even better than GPU since it’s actually MIMD with tons of cores so each can follow its own branching logic. And a bunch of servers can share the RAM (read only) in the M1.
