> On the software side, the system uses either a JIT compiler, static compiler, or binary instrumentation to split a single-threaded program into code segments to assign different blocks to different cores. It injects special instructions for flow control, register passing, and sync behavior, enabling the hardware to maintain execution integrity.

Itanium is back again?

As bad as it worked out I don't think Itanium tried to break Amdahl's law. And that is how I understand this magic multicore execution of single-thread code.

With Itanium they assumed that "smart compilers" would locally parallelize programs.

I'm surprised they even pursued this line of research, though they may be considering it just as a basic territory claim that they don't have a high expectation of turning into anything. Research into "implicit parallelism" has been done a lot over the years and the consistent result has been that there is a lot less than people intuitively think, and I mean, a lot less. I wouldn't hold out much hope for this... but then again, in a world of nearly frozen clock speeds, it wouldn't take much to stand out.
