◆ as_map()

std::map< std::string, double > q3::ProfilingCounters::DavidsonTimingAccumulator::as_map ( ) const

inline

The same breakdown print_summary() logs, as data.

Caveat for anyone doing arithmetic on these: the four hamiltonian_* sub-component timers are NOT a partition of hamiltonian_application. They are accumulated in the applicator (hamiltonian_applicator/serial.hpp) while the parent is accumulated around the call site in davidson.hpp, and the sub-components are reached from paths the parent timer does not wrap – a 2-atom silicon run reports 72.9 ms of hamiltonian_fft against 52.2 ms of hamiltonian_application. Use them to compare like with like across configurations, not to decompose the parent.

Kept beside the printer so the two cannot drift: a stage added to one and forgotten in the other is the failure mode this guards against. Returns a flat map of stage name to milliseconds; the caller decides where it goes.

◆ total_time_ms()

double q3::ProfilingCounters::DavidsonTimingAccumulator::total_time_ms ( ) const

inline

The same sum print_summary() reports as TOTAL. The Hamiltonian sub-components (fft, kinetic, nonlocal, allreduce) are deliberately excluded: they partition hamiltonian_application, so adding them again would double-count it.
