> kHz, not MHz Ha, I overestimated the capabilities of scaleout :D I figured if you added enough racks you could go that high... but yeah, that's asking for the equivalent of total coherency on a piece of software running simultaneously across thousands(?) of nodes. (Ha, I wonder if the current systems use 50Gbit networking. Or 100Gbit? Wow...) > A lot more simulation happens at the subsystem-level. You can isolate some subsystem, such as a cache controller, and then manufacture traces of the communication it does with the rest of the chip. Then you can just simulate that part at much lower cost, do tweaks, see how the operation changes under the simulation, and repeat. Right, that makes sense. And interestingly, that sounds similar to how retro/hobbyist emulation systems do things too. Emulate the exact behavior necessary for a specific set of things to work the way you want.
