Adding intrinsic support for the Tracy profiler by hkaiser · Pull Request #6858 · TheHPXProject/hpx

hkaiser · 2026-01-23T23:35:24Z

See for the Tracy profiler: https://github.com/wolfpld/tracy

flyby: fixing issues in the likwid bindings
flyby: adding names to some of the spinlocks

The integration covers:

thread names
HPX thread execution
HPX locks (hpx::spinlock, hpx::mutex)
HPX Performance counters (visualized as custom Tracy plots)
