Great question!

Short answer: GPU

Long answer: CUDA

Seriously though. Implementing a full high-level lang in parallel is HARD, so, to simplify it greatly, we made IC nodes 64-bit, which allows us to use native 64-bit atomic operations in many parts of the implementation. Since each 64-bit node has 2 ports, that gives us 32 bits per port. And since we use 3 bits for the tag, that leaves us with 29 bit payloads. We used that space to easily implement unboxed numbers (f24, u24, i24).

That said, we will have (boxed) 64-bit numbers soon! With this foundation in place, adding them is a matter of coding. I just want to have some time to let people use the limited version, find bugs, etc., before I add more stuff.
