NUMA will be much more important. This will really push on memory hierarchy aware data structures and programs.

- jabl 7y agoHmm, I would say the opposite. If all the memory and CPU cores are integrated on a single wafer, the penalty for off-chip access would be much less than if you had to go through a PCB.
- mjevans 7y agoIt'll be less than a networked cluster, but it still mattered with Threadripper units and I'd expect a racked board of this nature to expose more disparity between accessing memory in other chiplet areas.
