Global Variables

Description

Contains all variables, arrays and derived types instances shared throughout the code. Specifically, it contains definitions of the effective_bath, the gfmatrix and the sector data structures.

Quick access

Types:

h_operator, sector_map, sector, gfspectrum, gfchannel, gfmatrix

Variables:

ed_file_suffix, imphloc, neigen_sector, nlevels, ns, ns_orb, ns_ud, nsectors, sph0, sph0d, sph0dws, sph0e_eph, sph0nd, sph0ph_eph, sph0ups

Routines:

allocate_gfmatrix(), deallocate_gfmatrix(), write_gfmatrix(), read_gfmatrix()

Used modules

  • sf_constants

  • sf_iotools

  • ed_sparse_matrix: This class defines a data structure to efficiently store sparse matrices into dedicated CSR matrices, featuring support to MPI parallel storage, so that each matrix is spread across the threads.

  • ed_input_vars: Contains all global input variables which can be set by the user through the input file. A specific preocedure ed_read_input() should be called to read the input file using parse_input_variable() procedure from SciFortran. All variables are automatically set to a default, looked for and updated by reading into the file and, sequentially looked for and updated from command line (std.input) using the notation variable_name=variable_value(s) (case independent).
