16. Less Coffee, Better Sleep (www.marginalia.nu)
As an experiment, I’ve reduced my coffee-intake to a single cup a day for about a week now. It’s made an enormous difference in sleep, mood and energy. I get tired at night, fall asleep quickly, and wake up refreshed.
As mentioned previously in the context of morning sunlight exposure—another thing that’s aided my sleeping habits, but is somewhat less practical to sustain as it requires fair weather—I’ve always been slow to get going in the morning, active at night, bad at getting to bed at sane hours. Tired when I should be awake, and awake when I should be tired.

27. Characterizing Warp Divergence from Pascal to Blackwell (arxiv.org)
Since Volta introduced Independent Thread Scheduling (ITS), NVIDIA GPUs have been widely assumed to handle warp divergence in a fixed manner. We test this assumption across Ampere, Hopper, and datacenter and consumer Blackwell GPUs, using pre-ITS Pascal as a baseline. Combining cycle-accurate microbenchmarks, hardware counters, and static analysis of compiler-generated SASS, we separate stable behavior from architectural change. Across all tested generations, divergent paths serialize linearly with the number of paths $k$, following $T(k) \approx sk$ with no super-linear reconvergence penalty. Warp execution efficiency falls as $32/k$, the penalty is independent of occupancy, and predication removes the serialization cost. The same behavior appears on Pascal, showing that this programmer-visible cost model predates ITS. The compiler-emitted reconvergence machinery, however, has changed substantially. Pascal uses a per-warp SSY/SYNC instruction stack, whereas later generations use barrier-register instructions. Deferred reconvergence beyond the immediate post-dominator falls from 29 cases on Ampere to 2 on Blackwell. Blackwell also introduces a two-tier convergence-barrier classification, uniform-branch instructions, and explicit partial-mask warp synchronization, none of which appear on Ampere or Hopper. Controlled bit-flip experiments indicate that the new barrier class is a static compiler classification with no observable runtime effect in our tests. Thus, divergence retains a stable and predictable performance cost even as NVIDIA's control-flow ISA and reconvergence mechanisms continue to evolve.
NVIDIA’s approach to warp divergence in its GPUs has been taken for granted since the introduction of Independent Thread Scheduling. This study evaluates how different GPU architectures, from Pascal to Blackwell, actually manage warp divergence, revealing insights into their performance and architectural changes over generations.
