Member Function Documentation

◆ band_rank_index()

int q3::execution::QuantumSystemExecutionPolicy::band_rank_index ( ) const

inline

Index of this process within its band group (0 = band root).

Definition at line 46 of file init.hpp.

References q3::execution::ExecutionPolicy::group_rank_index().

◆ band_size()

int q3::execution::QuantumSystemExecutionPolicy::band_size ( ) const

inline

Number of processes collaborating within this band group.

1 means each process diagonalizes its quantum states alone (no band parallelism); >1 means the diagonalization work of each quantum state is shared across the group.

Definition at line 39 of file init.hpp.
