Perf Support For 2,048 CPU Cores Is Becoming Not Enough - Patches Bump Kernel Limit

Today's the day the prophesy becomes true.

- Thank god we were able to ditch flash player!
  
  I suppose we reached 4096 CPU support before full screen Flash support, just in a different way. Maybe somebody who used Linux in the Flash era can comment if it ever was working well.
How long until CPUs and GPUs just merge into one thing
- Probably never. Those 2048 cores are all separate threads. GPUs work with a cluster of cores all following a single thread of execution.
  MIMD Vs SIMD.
- You mean like an APU?
  
  Not OP, but I doubt that's what he meant. An APU still has a CPU and a GPU on it as separate things.
Intel has been making CPUs with integrated GPUs for ages, i7-6700K with UHD630 graphics for example, the thing is they contain a very small number of shaders, etc, because there is only so much real-estate on a single die and these weren't really intended for gaming, just providing enough GPU for a basic display, watch videos, etc.
- Can have a shared power envelope and naturally shares heat dissipation - which can both be limiters to simultaneously making full use of integrated graphics & CPU as well, even if the integrated graphics were powerful enough for gaming.
