Quick access

Variables:

get_lorder_lm_blocking, get_snake_lm_blocking, get_standard_lm_blocking, get_subblocks, llm, llmmag, lm2, lm22l, lm22lm, lm22m, lm2l, lm2lma, lm2lms, lm2m, lm_balance, lo_map, lo_sub_map, nlmbs2, sizelmb2, st_map, st_sub_map, ulm, ulmmag

Routines:

Needed modules

• iso_fortran_env (output_unit())

• precision_mod: This module controls the precision used in MagIC

• mem_alloc (memwrite(), bytes_allocated()): This little module is used to estimate the global memory allocation used in MagIC

• parallel_mod (nthreads(), rank(), n_procs(), rank_with_l1m0(), load(), getblocks()): This module contains the blocking information

• truncation (lm_max(), l_max(), n_theta_max(), minc(), n_r_max(), m_max(), m_min()): This module defines the grid points and the truncation

• logic (l_save_out(), l_finite_diff(), l_mag()): Module containing the logicals that control the run

• output_data (n_log_file(), log_file()): This module contains the parameters for output control

• lmmapping (mappings(), allocate_mappings(), deallocate_mappings(), allocate_subblocks_mappings(), deallocate_subblocks_mappings(), subblocks_mappings())

• useful (logwrite(), abortrun()): This module contains several useful routines.

• constants (one()): module containing constants and parameters used in the code.
