sigh. I want to love this game. I really do. I guess this is a computer science problem nobody can solve because even in rimworld this crap goes on.

So the least available answer is less of how to unroll the algorithm itself across multiple cores and more in how to evenly spread each instruction expressed by the compiler out to each core. This has been accomplished by MIT with their bare metal exokernel. I haven't delved into the specifics but the kernel accomplishes this by spreading all instructions across cores.
