tiny-differentiable-simulator
Tiny Differentiable Simulator is a header-only C++ and CUDA physics library for reinforcement learning and robotics with zero dependencies.
Check out Tracy[1]. If you run it as root, it provides a lot of "extra" information, such as when your threads get moved between CPUs. Actually, I saw this post and thought "why should I bother when I already have Tracy?" If anyone has an answer to that, I'm curious to know (:
Tracy is still a frame-based profiler, though.
If you want general system-wide profiling more focused on throughput rather than latency, then I've had a good experience generating flame graphs[2] using plain Linux perf.

Yes, Chrome about://tracing is great to visualize your custom timing data. Happy used for the last 5 years in Bullet and recent physics engines, including events across tracing multiple threads:
