alt Hacker NewsYes, I'm pointing out the fact that the programmer is expected to manage the ALAT, and that these machines do not automatically recover from cases where your advanced loads are incorrect. That process is expected to be part of the instruction stream, and [we have collectively learned that] that's an expensive feedback loop.
Yes, it doesn't require determinism to work, but it means that your performance is especially sensitive to nondeterminism because the compiler cannot account for loads and stores that occur online. The SDM (see vol 1, section 9.5.1) describes this idea pretty well.
You didn't generally need to manage the ALAT as a programmer.
You can, in the same way that you can manually manage reservation station port residency as a programmer in an OoO core to get maximum throughput, but neither of those are required in normal programming.
