states_elec_group_oct_m::states_elec_group_t Type Reference

Group of electronic states. More...

Detailed Description

Group of electronic states.

This class represents a group of batches of wave functions. It contains groups of blocks (batches) electronic states, represented by wfs_elec_oct_m::wfs_elec_t, together with the meta-data how these blocks are organized.

Each block contains wave functions with the same k point. The blocks can be distributed over nodes, when using state parallelization.
