UpDown: Efficient Manycore based on Many Threading & Scalable Memory Parallelism

Yet another manycore proposal, but I feel each time we're getting closer. Bandwidth is one of the few dimensions still growing, and there's something to unlock by shaping computation by this firehose of bits.

However it seems the software part is always a blocker, and these architecture only address well a handful of program types.

Is this time different? I think it is. The paradigm here is about small threads that yield very often, and we have that way of programming: Erlang, Go, Java's virtual threads.
