} From aa9e51574203b005fadd94cca10696f5740405f4 Mon Sep 17 00:00:00 2001 From: abacus_fixer Date: Wed, 16 Sep 2026 11:11:16 +0800 Subject: [PATCH 002/130] module_charge: aggregate Charge_Mixing params into MixingConfig Introduce a MixingConfig POD that bundles the INPUT mixing parameters with the runtime globals (nspin, scf_thr_type, double_grid), and change set_mixing from a 12-argument interface to set_mixing(const MixingConfig&, double&, double&). Charge_Mixing now stores the config and reads nspin / scf_thr_type / double_grid from it instead of PARAM.inp / PARAM.globalv, removing the direct PARAM reads in set_mixing and init_mixing. The single production call site (esolver_ks.cpp) fills the config, and the unit test drives set_mixing via a make_cfg() helper. The '#define private public' access hack is kept for now with a TODO: the test still must write Parameter::input/sys, Charge::_space_* and XC_Functional privates, which need the Step 4/5 global-state parameterization before it can be removed.

Extract the four branches into private methods -- read_rho_from_file, init_rho_atomic_and_tau, load_rho_from_restart, init_rho_from_wfc -- and leave init_rho as a thin sequence of stage calls. Logic is unchanged; the error flags are threaded through as parameters. The deepest stage (read_rho_from_file) now sits at complexity 19, down from 36 for the monolith.

Move the three bodies into a new charge_math namespace as free functions with those values passed explicitly, and leave the Charge members as thin forwarding wrappers so no caller outside the module changes. The kernels are now unit-testable in isolation and no longer coupled to Charge state. One behavior note: the pre-quit debug line that printed sum_rho to ofs_warning is dropped so the free function stays free of global-stream dependencies. charge_math.cpp is wired into the estate library and the charge_test target. --- source/source_estate/CMakeLists.txt | 1 + source/source_estate/module_charge/charge.cpp | 46 +----- .../module_charge/charge_init.cpp | 79 ++------- .../module_charge/charge_math.cpp | 155 ++++++++++++++++++ .../source_estate/module_charge/charge_math.h | 47 ++++++ source/source_estate/test/CMakeLists.txt | 2 +- 6 files changed, 219 insertions(+), 111 deletions(-) create mode 100644 source/source_estate/module_charge/charge_math.cpp create mode 100644 source/source_estate/module_charge/charge_math.h diff --git a/source/source_estate/CMakeLists.txt b/source/source_estate/CMakeLists.txt index a54b62394aa..4a5cd86787f 100644 --- a/source/source_estate/CMakeLists.txt +++ b/source/source_estate/CMakeLists.txt @@ -30,6 +30,7 @@ list(APPEND objects module_charge/gint_prec_ctrl.cpp module_charge/charge.cpp module_charge/charge_init.cpp + module_charge/charge_math.cpp module_charge/charge_mpi.cpp module_charge/charge_extra.cpp module_charge/charge_mixing.cpp diff --git a/source/source_estate/module_charge/charge.cpp b/source/source_estate/module_charge/charge.cpp index 798287c86dc..c6a646813b9 100644 --- a/source/source_estate/module_charge/charge.cpp +++ b/source/source_estate/module_charge/charge.cpp @@ -17,6 +17,7 @@ // even in a LSDA calculation. //---------------------------------------------------------- #include "charge.h" +#include "charge_math.h" #include "source_base/global_function.h" #include "source_base/global_variable.h" @@ -174,35 +175,8 @@ void Charge::allocate(const int& nspin_in, const bool kin_den) double Charge::sum_rho() const { - ModuleBase::TITLE("Charge", "sum_rho");

After the _space_* storage became std::vector (ecf5084d4), a copied/moved Charge leaves its rho/kin_r views dangling into another object's vector buffer, and a kin_r_save never allocated (ked_flag set after allocate) stays nullptr; both surface as a null rhoin deep inside MPI gather instead of at the source. Delete Charge's copy constructor/assignment so any value copy of the vector-aliasing views fails at compile time, and check kin_r_save in ctrl_output_fp before writing tau.cube so a missing allocation reports a clear message instead of tripping the MPI assert.

Bisecting between 83eb5d0f3 (good) and ecf5084d4 (bad) isolated the regression to ecf5084d4, which moved Charge's _space_* storage from raw new[] to std::vector. Root cause: with 4 ranks the FFT grid is slab-decomposed so that the last rank owns zero real-space points (nrxx == 0, confirmed via a temporary diagnostic printing fn/is/rank/nrxx at the reduce call site). Before ecf5084d4, _space_rho = new double[nspin * 0] == new double[0] returned a unique non-null pointer, so rho_save[is] was non-null and the assert passed. After the change, an empty vector's .data() returns nullptr, so the rank with nrxx == 0 handed a null rhoin to reduce and tripped the assert (Debug) or fed MPI_Gatherv a null buffer (Release). A rank with nrxx == 0 is legitimate: MPI_Gatherv is invoked with sendcount 0 and ignores the send buffer. Relax the assert to only flag a null buffer when nrxx != 0, and revert the now-unneeded kin_r_save guard in ctrl_output_fp (it would have falsely aborted on the nrxx == 0 rank).

5 public functions become module_charge::symmetrize_rho / cal_rhog_symm (2 overloads) / cal_rhog_symm_soc (2 overloads) - 2 cross-TU helpers (psymmg/psymmg_soc) moved to module_charge::detail via chg_symm_detail.h - 3 internal MPI helpers moved to anonymous namespace - Delete dead code psymm (real-space symmetrization, never called) - Remove empty ctor/dtor and parallel_grid.h include - Rename begin/begin_soc to cal_rhog_symm/cal_rhog_symm_soc for clarity - Update timer/TITLE labels from "Symmetry_rho" to "module_charge" - Migrate all 14 call sites and 1 test stub - Remove obsolete Makefile special rule (no more name collision) --- source/Makefile | 8 -

Continues the module_charge convention of stateless free functions in chg_* files. * charge_mixing_rho.cpp -> chg_tau.cpp: rename for the module_charge short-underscore convention; the file only contains mix_tau_recip. * Extract mix_tau_recip declaration from chg_rho_detail.h into a new chg_tau.h so chg_tau.cpp no longer pulls in the detail template helpers (make_twobeta_mix / pack_rho_mag / unpack_rho_mag). charge_mixing.cpp adds chg_tau.h while keeping chg_rho_detail.h for the template helpers it still uses. * Widen ModuleIO::read_vdata_palgrid's ofs_running parameter from std::ofstream& to std::ostream& (cube_io.h / read_cube.cpp). The body only uses operator<<, so std::ostream& is sufficient; this fixes the chg_init.cpp compile error where read_rho_file / read_kin_file (per project rules, std::ostream&) could not bind to the old std::ofstream& parameter. Existing callers passing std::ofstream& (GlobalV::ofs_running, test fixture) convert implicitly via base-class reference. Build lists updated: source/Makefile.Objects and source/source_estate/{CMakeLists.txt,test/CMakeLists.txt}. Verification: chg_init.* changes compile-verified by user before this session; chg_tau rename and chg_tau.h extraction not yet compile-verified; cube_io type widening not yet compile-verified. --- source/Makefile.Objects | 4 +- source/source_estate/CMakeLists.txt | 4 +- source/source_estate/module_charge/charge.h | 28 -- .../module_charge/charge_init.cpp | 305 ------------- .../module_charge/charge_mixing.cpp | 1 + .../source_estate/module_charge/chg_init.cpp | 420 ++++++++++++++++++ source/source_estate/module_charge/chg_init.h | 37 ++ .../module_charge/chg_rho_detail.h | 28 +- .../{charge_mixing_rho.cpp => chg_tau.cpp} | 2 +- source/source_estate/module_charge/chg_tau.h | 44 ++ source/source_estate/test/CMakeLists.txt | 2 +- source/source_io/module_output/cube_io.h | 2 +- source/source_io/module_output/read_cube.cpp | 2 +- 13 files changed, 512 insertions(+), 367 deletions(-) delete mode 100644 source/source_estate/module_charge/charge_init.cpp create mode 100644 source/source_estate/module_charge/chg_init.cpp create mode 100644 source/source_estate/module_charge/chg_init.h rename source/source_estate/module_charge/{charge_mixing_rho.cpp => chg_tau.cpp} (99%) create mode 100644 source/source_estate/module_charge/chg_tau.h diff --git a/source/Makefile.Objects b/source/Makefile.Objects index cedd880e8d6..8d1799693c1 100644 --- a/source/Makefile.Objects +++ b/source/Makefile.Objects @@ -827,7 +827,7 @@ OBJS_SRCPW=h_ewald_pw.o\ chg_routine.o\ charge.o\ chg_atomic.o\ - charge_init.o\ + chg_init.o\ chg_tools.o\ chg_parallel.o\ chg_extra.o\ @@ -835,7 +835,7 @@ OBJS_SRCPW=h_ewald_pw.o\ chg_dmr.o\ chg_drho.o\ chg_precond.o\ - charge_mixing_rho.o\ + chg_tau.o\ chg_symm.o\ chg_symm_detail.o\ chg_uspp.o\ diff --git a/source/source_estate/CMakeLists.txt b/source/source_estate/CMakeLists.txt index e4eb55ebb70..2c29e5e6757 100644 --- a/source/source_estate/CMakeLists.txt +++ b/source/source_estate/CMakeLists.txt @@ -30,7 +30,7 @@ list(APPEND objects module_charge/chg_routine.cpp module_charge/charge.cpp module_charge/chg_atomic.cpp - module_charge/charge_init.cpp + module_charge/chg_init.cpp module_charge/chg_tools.cpp module_charge/chg_parallel.cpp module_charge/chg_extra.cpp @@ -38,7 +38,7 @@ list(APPEND objects module_charge/chg_dmr.cpp module_charge/chg_drho.cpp module_charge/chg_precond.cpp - module_charge/charge_mixing_rho.cpp + module_charge/chg_tau.cpp module_charge/chg_symm.cpp module_charge/chg_uspp.cpp module_charge/chg_symm_detail.cpp diff --git a/source/source_estate/module_charge/charge.h b/source/source_estate/module_charge/charge.h index b0e4654d475..d891e8121f0 100644 --- a/source/source_estate/module_charge/charge.h +++ b/source/source_estate/module_charge/charge.h @@ -124,34 +124,6 @@ class Charge void destroy();

CC reduced to 7, score 40->100. - Replace all PARAM.inp.nelec/domag/domag_z/test_charge and GlobalV::ofs_warning with explicit AtomicRhoCfg parameter. - Remove unused parameter.h include. - Add chg_atomic_detail.h declaring detail helpers and RhoG3dCtx. chg_init/chg_extra/esolver_*: - Pass AtomicRhoCfg through call sites of atomic_rho, extrapolate_charge, and update_delta_rho. Bug fixes: - chg_drho_inner.cpp: fix duplicate const (const MixingConfig const& -> const MixingConfig&) and add detail:: prefix to helper calls. - chg_mix_rho.cpp: use mixing.get()/mixing_highf.get() for unique_ptr. - chg_tools.cpp: fix numeric -> numeric[it] in set_rho_core. Memory safety / cleanup: - Replace ModuleBase::GlobalFunc::ZEROS with std::fill in charge.cpp, chg_symm_detail.cpp, chg_tools.cpp; remove redundant ZEROS calls that precede full overwrites in chg_dmr.cpp and chg_mix_rho.cpp. --- source/Makefile.Objects | 3 + source/source_esolver/esolver_fp.cpp | 18 +- .../source_esolver/esolver_ks_lcao_tddft.cpp | 11 +- source/source_estate/CMakeLists.txt | 1 + source/source_estate/module_charge/charge.cpp | 31 +- .../module_charge/chg_atomic.cpp | 454 ++---------------- .../source_estate/module_charge/chg_atomic.h | 28 +- .../module_charge/chg_atomic_detail.h | 80 +++ .../module_charge/chg_atomic_inner.cpp | 421 ++++++++++++++++ .../source_estate/module_charge/chg_dmr.cpp | 3 - .../module_charge/chg_drho_inner.cpp | 20 +- .../source_estate/module_charge/chg_extra.cpp | 12 +- .../source_estate/module_charge/chg_extra.h | 13 +- .../source_estate/module_charge/chg_init.cpp | 14 +- .../module_charge/chg_mix_rho.cpp | 10 +- .../module_charge/chg_symm_detail.cpp | 11 +- .../source_estate/module_charge/chg_tools.cpp | 7 +- source/source_estate/test/CMakeLists.txt | 2 +- .../source_estate/test/charge_extra_test.cpp | 36 +- 19 files changed, 690 insertions(+), 485 deletions(-) create mode 100644 source/source_estate/module_charge/chg_atomic_detail.h create mode 100644 source/source_estate/module_charge/chg_atomic_inner.cpp diff --git a/source/Makefile.Objects b/source/Makefile.Objects index b99d6ae36a1..9eb2aa8c506 100644 --- a/source/Makefile.Objects +++ b/source/Makefile.Objects @@ -827,13 +827,16 @@ OBJS_SRCPW=h_ewald_pw.o\ chg_routine.o\ charge.o\ chg_atomic.o\ + chg_atomic_inner.o\ chg_init.o\ chg_tools.o\ chg_parallel.o\ chg_extra.o\ chg_mix.o\ + chg_mix_rho.o\ chg_dmr.o\ chg_drho.o\ + chg_drho_inner.o\ chg_precond.o\ chg_tau.o\ chg_symm.o\ diff --git a/source/source_esolver/esolver_fp.cpp b/source/source_esolver/esolver_fp.cpp index d84dd2b1049..783e7fb1627 100644 --- a/source/source_esolver/esolver_fp.cpp +++ b/source/source_esolver/esolver_fp.cpp @@ -2,6 +2,7 @@ #include "source_base/tool_quit.h" #include "source_cell/cal_ux.h" +#include "source_estate/module_charge/chg_atomic.h" #include "source_estate/module_charge/chg_symm.h" #include "source_cell/read_pp_ucell.h" #include "source_estate/param_update.h" @@ -165,7 +166,13 @@ void ESolver_FP::after_scf(UnitCell& ucell, const int istep, const bool conv_eso ModuleIO::output_efermi(conv_esolver, this->pelec->eferm.ef); //!

INPUT values are now passed explicitly: - MixingConfig gains scf_nmax for the drho oscillation history - reduce_diff_pools/rho_mpi/kin_r_mpi take kpar, all_ks_run, bndpar, nspin, out_elf from callers instead of GlobalV::KPAR/PARAM - Charge::kin_density/allocate/check_rho/renormalize_rho/init_final_scf take out_elf/test_charge/nelec as arguments with validation asserts - new InitRhoCfg aggregates INPUT values for init_rho - ScfMixingCtx gains ks_run; dm2rho takes nelec and drops its default skip_normalize argument per governance rule 5 No behavior change: save_rho_before_sum_band now uses the member nspin set by allocate, identical to the previously read PARAM.inp.nspin. --- source/source_esolver/esolver_dfpt_pw.cpp | 2 +- source/source_esolver/esolver_dm2rho.cpp | 2 +- source/source_esolver/esolver_double_xc.cpp | 20 ++++++-- source/source_esolver/esolver_fp.cpp | 4 +- source/source_esolver/esolver_ks.cpp | 18 ++++++- source/source_esolver/esolver_ks_lcao.cpp | 2 +- .../source_esolver/esolver_ks_lcao_tddft.cpp | 2 +- .../source_esolver/esolver_lr_lcao_tddft.cpp | 4 +- source/source_esolver/esolver_of.cpp | 20 ++++++-- source/source_esolver/esolver_of_tool.cpp | 4 +- source/source_estate/elecstate_lcao.cpp | 4 +- source/source_estate/elecstate_pw.cpp | 7 ++- source/source_estate/elecstate_pw_cal_tau.cpp | 7 ++- source/source_estate/init_scf.cpp | 2 +- source/source_estate/module_charge/charge.cpp | 44 ++++++++--------- source/source_estate/module_charge/charge.h | 49 ++++++++++++++++--- .../source_estate/module_charge/chg_init.cpp | 33 +++++++------ source/source_estate/module_charge/chg_init.h | 25 +++++++++- .../source_estate/module_charge/chg_mix.cpp | 3 +- .../source_estate/module_charge/chg_mix_cfg.h | 1 + .../module_charge/chg_parallel.cpp | 40 +++++++++------ .../module_charge/chg_parallel.h | 26 ++++++++-- .../module_charge/chg_routine.cpp | 4 +- .../source_estate/module_charge/chg_routine.h | 1 + source/source_estate/module_dm/init_dm.cpp | 2 +- .../source_estate/module_pot/pot_xc_fdm.cpp | 2 +- source/source_estate/test/charge_test.cpp | 30 ++++++------ .../test/elecstate_base_test.cpp | 7 +-- .../source_estate/test/elecstate_pw_test.cpp | 7 +-- source/source_estate/test/test_chg_mix.cpp | 1 + .../source_estate/test/test_chg_parallel.cpp | 18 +++++-- source/source_io/module_wf/read_wf2rho_pw.cpp | 3 +- source/source_io/test/read_wf2rho_pw_test.cpp | 3 +- source/source_lcao/lcao_set.cpp | 2 +- .../module_operator_lcao/veff_dh.cpp | 4 +- .../module_rdmft/update_state_rdmft.cpp | 4 +- source/source_lcao/rho_tau_lcao.cpp | 5 +- source/source_lcao/rho_tau_lcao.h | 5 +- source/source_pw/module_pwdft/stress_mgga.cpp | 6 ++- source/source_pw/module_stodft/sto_iter.cpp | 6 ++- 40 files changed, 292 insertions(+), 137 deletions(-) diff --git a/source/source_esolver/esolver_dfpt_pw.cpp b/source/source_esolver/esolver_dfpt_pw.cpp index e125b1d431c..20ba662a108 100644 --- a/source/source_esolver/esolver_dfpt_pw.cpp +++ b/source/source_esolver/esolver_dfpt_pw.cpp @@ -45,7 +45,7 @@ class XC_First_Order_FDM : public ModuleDFPT::XC_First_Order fdm_ = new elecstate::PotXC_FDM(rho_basis, chg0, ucell); chg1_ = new Charge(); chg1_->set_rhopw(rho_basis); - chg1_->allocate(chg0->nspin, false); + chg1_->allocate(chg0->nspin, false, PARAM.inp.test_charge); veff_1_.create(chg0->nspin, chg0->nrxx); } diff --git a/source/source_esolver/esolver_dm2rho.cpp b/source/source_esolver/esolver_dm2rho.cpp index 4f1c042deb7..0cfde09a6d7 100644 --- a/source/source_esolver/esolver_dm2rho.cpp +++ b/source/source_esolver/esolver_dm2rho.cpp @@ -66,7 +66,7 @@ void ESolver_DM2rho::runner(BaseCell& basecell, const int istep) // it's dangerous to design psiToRho function like this, mohan note 20251024 // this->pelec->psiToRho(*this->psi); - LCAO_domain::dm2rho(this->dmat.dm->get_DMR_vector(), this->inp_->nspin, &this->chr); + LCAO_domain::dm2rho(this->dmat.dm->get_DMR_vector(), this->inp_->nspin, &this->chr, this->inp_->nelec, false); int nspin0 = this->inp_->nspin == 2 ?

A rank may legitimately own zero real-space grid points (nrxx == 0) when the grid is decomposed across more processes than it has z-slabs (e.g. a 3x3x3 big-cell grid on 4 processes leaves one rank with no slab); its zero-sized vectors then return null data() pointers even though the packing loops perform no access. The unconditional check made LCAO nspin==2 real-space mixing abort with "pack_rho_mag pointer is null" on such ranks. Restrict the null-pointer check to n > 0, matching the convention already used by Parallel_Grid::reduce (only a null buffer with a non-zero size is a genuine bug). n < 0 remains a hard error.

In variable-cell calculations (NPT), pw_rho/pw_rhod are NOT rebuilt on cell change (only pw_wfc is), so rhopw->omega keeps the initial cell volume while ucell.omega is updated every MD step. The stale volume made sum_rho() return a wrong electron count, which made renormalize_rho() scale rho by the wrong factor, corrupting the stress (deviation ~0.002 in 095_PW_NPT) while the total energy stayed near-correct (variational, second-order sensitive). Fix: add an explicit omega parameter to Charge::sum_rho() and renormalize_rho(); all call sites (init_scf, chg_routine, LCAO dm2rho path through HSolverLCAO/dmToRho, RDMFT update_charge, OFDFT renormalize_psi) now pass ucell.omega. This mirrors the existing check_rho(..., ucell.omega) pattern. Also mark three other rhopw->omega users with BUG(investigate) comments: get_local_pp_energy, cal_delta_escf, and Makov-Payne correction. These are pre-existing and were not changed by the refactor; they may have the same stale-volume issue in NPT and should be investigated separately.

The bug manifests as a ~16% overestimate of rhopw->omega on the first MD step (reference-cell volume instead of actual-cell volume) and silently wrong stress/energy values. Since properly fixing this requires refactoring PW_Basis to separate the reference-cell FFT grid (nx/ny/nz) from the physical-cell lattice quantities (lat0/tpiba/G/GGT/omega), temporarily disable the feature: - read_input_item_md.cpp: WARNING_QUIT if ref_cell_factor != 1.0 - input_parameter.h: FIXME comment explaining the disable and the refactor required to re-enable - setup_pwrho.cpp / setup_pwwfc.cpp: NOTE comments at the five initgrids(ref_cell_factor * ucell.lat0, ...) call sites explaining the staleness issue and the initgrids_ref/initgrids_actual split needed when the feature is restored - tests/01_PW/CASES_CPU.txt and CASES_GPU.txt: skip 095_PW_NPT (its INPUT sets ref_cell_factor=1.05, which is now blocked) The 3 BUG(investigate) markers in estate_e_terms.cpp, elecstate_energy.cpp, and makov_payne.cpp are left in place as remainders that those call sites also need review when the reference- cell mechanism is re-enabled. --- .../module_parameter/input_parameter.h | 10 ++++++++ .../module_parameter/read_input_item_md.cpp | 24 +++++++++++++++++++ source/source_pw/module_pwdft/setup_pwrho.cpp | 12 ++++++++++ source/source_pw/module_pwdft/setup_pwwfc.cpp | 19 +++++++++++---- tests/01_PW/CASES_CPU.txt | 2 +- tests/01_PW/CASES_GPU.txt | 2 +- 6 files changed, 62 insertions(+), 7 deletions(-) diff --git a/source/source_io/module_parameter/input_parameter.h b/source/source_io/module_parameter/input_parameter.h index c5afaaaae1e..a550773c8a2 100644 --- a/source/source_io/module_parameter/input_parameter.h +++ b/source/source_io/module_parameter/input_parameter.h @@ -187,6 +187,16 @@ struct Input_para // ============== #Parameters (5.Molecular dynamics) =========================== MD_para mdp; + // FIXME(liuyu): ref_cell_factor is currently DISABLED.

drop dead mixing_gg0 members The chg_precond refactor (commit 6d127d517) made the Kerker kernels read cfg_ (immutable INPUT snapshot) instead of Charge_Mixing members, but close_kerker_gg0() kept writing the now-dead mixing_gg0/mixing_gg0_mag members. As a result, the non-separate-loop EXX path in exx_lri_interface.hpp silently failed to disable Kerker after convergence. Fix: add a kerker_disabled_ flag on Charge_Mixing that the mix_rho_recip/ mix_rho_real screening lambdas short-circuit on. The flag lives on the object, not in cfg_, so the immutable INPUT snapshot invariant is preserved. Also drop the now-dead members mixing_gg0/mixing_gg0_mag/mixing_gg0_min/ mixing_angle/mixing_dmr and the get_mixing_gg0() getter; set_mixing/init_mixing now read these from cfg_ directly. Add CloseKerkerGg0DisablesScreenReal regression test that compares close_kerker_gg0() output against the cfg.mixing_gg0=0 baseline and proves the flag is load-bearing. --- .../source_estate/module_charge/chg_mix.cpp | 32 ++--- source/source_estate/module_charge/chg_mix.h | 21 +-- .../module_charge/chg_mix_rho.cpp | 13 +- .../module_charge/unittests/test_chg_mix.cpp | 125 +++++++++++++++++- 4 files changed, 160 insertions(+), 31 deletions(-) diff --git a/source/source_estate/module_charge/chg_mix.cpp b/source/source_estate/module_charge/chg_mix.cpp index 995397be5c0..dd96c48fb24 100644 --- a/source/source_estate/module_charge/chg_mix.cpp +++ b/source/source_estate/module_charge/chg_mix.cpp @@ -28,20 +28,20 @@ void Charge_Mixing::set_mixing(const MixingConfig& cfg, double& omega_in, double& tpiba_in) { - // store the aggregated config;

normalize_and_check renormalizes uniform density to nelec. - test_chg_atomic.cpp: atomic_rho ntype==0 path (skips atom loop) and spin_number_need==3 abort path.

Tests that only call func_xyz_to_updown now include the lighter dm_tools.h directly and link dmr_cal.cpp for the moved definitions. --- .../module_symmetry/test/CMakeLists.txt | 1 + .../test/symm_rho_soc_test.cpp | 2 +- .../module_dm/density_matrix.cpp | 64 ------------------- .../source_estate/module_dm/density_matrix.h | 56 ++-------------- source/source_estate/module_dm/dm_shift.h | 32 ++++++++++ source/source_estate/module_dm/dm_tools.h | 58 +++++++++++++++++ source/source_estate/module_dm/dmr_cal.cpp | 62 ++++++++++++++++++ .../module_dm/test/CMakeLists.txt | 2 +- .../test/test_soc_magnetization_roundtrip.cpp | 2 +- 9 files changed, 161 insertions(+), 118 deletions(-) create mode 100644 source/source_estate/module_dm/dm_shift.h create mode 100644 source/source_estate/module_dm/dm_tools.h diff --git a/source/source_cell/module_symmetry/test/CMakeLists.txt b/source/source_cell/module_symmetry/test/CMakeLists.txt index 4401d65abf6..9635231c683 100644 --- a/source/source_cell/module_symmetry/test/CMakeLists.txt +++ b/source/source_cell/module_symmetry/test/CMakeLists.txt @@ -22,6 +22,7 @@ AddTest( LIBS parameter base ${math_libs} device symmetry SOURCES symm_rho_soc_test.cpp ${ABACUS_SOURCE_DIR}/source_estate/module_dm/density_matrix.cpp + ${ABACUS_SOURCE_DIR}/source_estate/module_dm/dmr_cal.cpp ${ABACUS_SOURCE_DIR}/source_hamilt/module_hcontainer/base_matrix.cpp ${ABACUS_SOURCE_DIR}/source_hamilt/module_hcontainer/hcontainer.cpp ${ABACUS_SOURCE_DIR}/source_hamilt/module_hcontainer/atom_pair.cpp diff --git a/source/source_cell/module_symmetry/test/symm_rho_soc_test.cpp b/source/source_cell/module_symmetry/test/symm_rho_soc_test.cpp index 01258305d67..6eaf80b60e9 100644 --- a/source/source_cell/module_symmetry/test/symm_rho_soc_test.cpp +++ b/source/source_cell/module_symmetry/test/symm_rho_soc_test.cpp @@ -6,7 +6,7 @@ #include "../symmetry.h" #include "../symm_rot_spin.h" #include "source_cell/unitcell.h" -#include "source_estate/module_dm/density_matrix.h" // real func_xyz_to_updown +#include "source_estate/module_dm/dm_tools.h" // real func_xyz_to_updown /************************************************ * unit test of Symmetry::rhog_symmetry_nspin4 diff --git a/source/source_estate/module_dm/density_matrix.cpp b/source/source_estate/module_dm/density_matrix.cpp index 4934f202aad..a7c8078d939 100644 --- a/source/source_estate/module_dm/density_matrix.cpp +++ b/source/source_estate/module_dm/density_matrix.cpp @@ -218,70 +218,6 @@ void DensityMatrix::switch_dmr(const int mode) -template <> -void DensityMatrix_Tools::func_exp_mul_dmk( - const std::complex kphase, - const std::vector>& DMK_mat_trans, - double* target_DMR_mat) -{ - const std::size_t mat_size = DMK_mat_trans.size(); - for(std::size_t i = 0; i < mat_size; i++) - { - target_DMR_mat[i] - += kphase.real() * DMK_mat_trans[i].real() - - kphase.imag() * DMK_mat_trans[i].imag(); - } -} - -template <> -void DensityMatrix_Tools::func_exp_mul_dmk>( - const std::complex kphase, - const std::vector>& DMK_mat_trans, - std::complex* target_DMR_mat) -{ - BlasConnector::axpy(DMK_mat_trans.size(), - kphase, - DMK_mat_trans.data(), - 1, - target_DMR_mat, - 1); -} - -template <> -void DensityMatrix_Tools::func_xyz_to_updown( - const std::complex tmp[4], - const int icol, - const int step_trace[4], - double* target_DMR_mat) -{ - target_DMR_mat[icol + step_trace[0]] = tmp[0].real() + tmp[3].real(); // rho_0 = (rho_upup + rho_downdown).real() - target_DMR_mat[icol + step_trace[1]] = tmp[1].real() + tmp[2].real(); // rho_x = (rho_updown + rho_downup).real() - // rho_y: the stored DM block is the complex conjugate of the physical 1-RDM P (cal_dm_psi builds - // DM_{ab}=sum conj(c_a) c_b = conj(P), so tmp[1]=DM_{ud}=conj(P_{ud})).

The member specializations drop their now-redundant flag assignments.
