From 92c371b8ff44ff12a8b2805e7807f3215bdf3c1d Mon Sep 17 00:00:00 2001 From: abacus_fixer Date: Sat, 29 Aug 2026 21:40:21 +0800 Subject: [PATCH 01/40] Slim down Plus_U_Base interface in dftu_base.h - Remove dead members with no callers: get_u_target, get_orbital_corr_data, deprecated get_pot_uterm_pw(iat), element-wise set_occ_mat, and mix_occ_mat (occupation mixing now goes through Charge_Mixing::mix_uom + sync_occ_to_uom) - Merge duplicate occ_mat_initialized accessors: keep the is_*/mark_* pair and update dftu_lcao_occ.cpp call sites accordingly - Replace unitcell.h/charge_mixing.h includes with forward declarations in dftu_base.h; add explicit includes to units that relied on them transitively (dftu_base.cpp, dftu_cal_occ_pw.cpp, dftu_output.cpp) and parallel_comm.h to stodft/hsolver units that used BP_WORLD/POOL_WORLD/INT_BGROUP indirectly Verified: full incremental build of all targets passes with no errors; repo-wide grep confirms no remaining references to the removed symbols. --- source/source_hsolver/hsolver_pw_sdft.cpp | 1 + .../source_lcao/module_dftu/dftu_lcao_occ.cpp | 24 ++++++-- source/source_pw/module_pwdft/dftu_base.cpp | 58 +------------------ source/source_pw/module_pwdft/dftu_base.h | 29 ++-------- .../module_pwdft/dftu_cal_occ_pw.cpp | 2 + source/source_pw/module_pwdft/dftu_output.cpp | 1 + source/source_pw/module_pwdft/onsite_proj.cpp | 4 +- source/source_pw/module_stodft/sto_dos.cpp | 1 + .../source_pw/module_stodft/sto_elecond.cpp | 1 + source/source_pw/module_stodft/sto_iter.cpp | 1 + source/source_pw/module_stodft/sto_tool.cpp | 1 + 11 files changed, 35 insertions(+), 88 deletions(-) diff --git a/source/source_hsolver/hsolver_pw_sdft.cpp b/source/source_hsolver/hsolver_pw_sdft.cpp index 339ac576a1c..eee59358463 100644 --- a/source/source_hsolver/hsolver_pw_sdft.cpp +++ b/source/source_hsolver/hsolver_pw_sdft.cpp @@ -1,6 +1,7 @@ #include "hsolver_pw_sdft.h" #include "source_base/global_function.h" +#include "source_base/parallel_comm.h" #include "source_base/parallel_device.h" #include "source_base/timer.h" #include "source_base/tool_title.h" diff --git a/source/source_lcao/module_dftu/dftu_lcao_occ.cpp b/source/source_lcao/module_dftu/dftu_lcao_occ.cpp index 247c8b1174f..b375ed56536 100644 --- a/source/source_lcao/module_dftu/dftu_lcao_occ.cpp +++ b/source/source_lcao/module_dftu/dftu_lcao_occ.cpp @@ -8,7 +8,7 @@ #include "source_lcao/hamilt_lcao.h" #endif -// copy_occ_mat(), zero_occ_mat(), mix_occ_mat(), set_occ_mat(ucell), +// copy_occ_mat(), zero_occ_mat(), set_occ_mat(ucell), // get_occ_mat_flat(), set_occ_mat_flat() // are now implemented in dftu_base.cpp as Plus_U_Base methods (inherited by Plus_U). @@ -584,13 +584,20 @@ void cal_occ_mat(const Parallel_Orbitals* pv, const bool gamma_only_local, const int nspin) { - bool occ_mat_initialized = dftu.get_occ_mat_initialized();

The IO free functions read_occup_m / local_occup_bcast now take an OccupationMatrix& instead of the raw nested vector, and write into it through the set()/mat() interface. write_occup_m / output already used the public get_occ_mat() accessors and are unchanged.

Plus_U_Base::cal_occ_pw remains as the thin orchestration wrapper. Verified: cmake --build build -j4 (exit 0).

Both now read all occupation-matrix state from dftu.occmat() (mat/mat_save/data/data_save/iatlnmipol2iwt/nspin/npol) and the Plus_U_Base accessors (get_orbital_corr_vec / is_occ_mat_initialized / mark_occ_mat_initialized), and use occmat().copy_to_save()/zero() instead of the duplicated hand-written copy/zero loops. The intermediate cal_occ_mat template forwarders shrink to a single direct call. MPI_Allreduce(MPI_COMM_WORLD) inside the accumulation is intentionally left unchanged: it has no exact Parallel_Reduce counterpart and was kept per the "only replace what maps cleanly" rule. Verified: cmake --build build -j4 (exit 0). This build has no test targets. --- .../source_lcao/module_dftu/dftu_lcao_occ.cpp | 238 ++++++------------ .../source_lcao/module_dftu/dftu_lcao_occ.h | 19 +- 2 files changed, 76 insertions(+), 181 deletions(-) diff --git a/source/source_lcao/module_dftu/dftu_lcao_occ.cpp b/source/source_lcao/module_dftu/dftu_lcao_occ.cpp index 9a64d91dfb2..9281f7dc388 100644 --- a/source/source_lcao/module_dftu/dftu_lcao_occ.cpp +++ b/source/source_lcao/module_dftu/dftu_lcao_occ.cpp @@ -3,15 +3,15 @@ #include "dftu_folding.h" #include "source_base/timer.h" #include "source_base/module_external/scalapack_connector.h" -#include "source_io/module_parameter/parameter.h" #include "source_estate/occ_matrix.h" +#include "source_io/module_parameter/parameter.h" #ifdef __LCAO #include "source_lcao/hamilt_lcao.h" #endif -// copy_occ_mat(), zero_occ_mat(), set_occ_mat(ucell), -// get_occ_mat_flat(), set_occ_mat_flat() -// are now implemented in dftu_base.cpp as Plus_U_Base methods (inherited by Plus_U). +// cal_occ_mat_k / cal_occ_mat_gamma take Plus_U& dftu directly and read all +// occupation-matrix state (occ/save arrays, lookup table, nspin/npol, and the +// occ_mat_initialized flag) from dftu.occmat() and the Plus_U_Base accessors. #ifdef __LCAO @@ -23,63 +23,21 @@ void DFTU_LCAO::cal_occ_mat_k(const Parallel_Orbitals* pv, const double& mixing_beta, hamilt::Hamilt>* p_ham, const bool gamma_only_local, -

Note: setup_dftu_lcao.cpp/h keep their names (they are not in module_dftu and represent the DFT+U setup workflow, not a basis-specific implementation).

for nspin=1 For nspin==1, uom_save is allocated as a single block (pot_index is doubled only when nspin==2). However, write_save_to_flat previously wrote both spin channels unconditionally, causing part of the first block to be overwritten and indices past the vector end to be accessed (undefined behavior via operator[]). Fix by guarding the channel-[1] write with `if (nspin_ == 2)`, consistent with write_to_flat() and read_from_flat() which already handle the two channels correctly. --- source/source_estate/occ_matrix.cpp | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) diff --git a/source/source_estate/occ_matrix.cpp b/source/source_estate/occ_matrix.cpp index 1ba881b45ae..89283ef5f17 100644 --- a/source/source_estate/occ_matrix.cpp +++ b/source/source_estate/occ_matrix.cpp @@ -291,11 +291,17 @@ void OccupationMatrix::write_save_to_flat(const UnitCell& cell, } else if (nspin_ == 1 || nspin_ == 2) { - const int half_size = uom_save.size() / 2; for (int mm = 0; mm < size; mm++) { uom_save[index[iat] + mm] = occ_[iat][target_l][0][0].c[mm]; - uom_save[half_size + index[iat] + mm] = occ_[iat][target_l][0][1].c[mm]; + } + if (nspin_ == 2) + { + const int half_size = uom_save.size() / 2; + for (int mm = 0; mm < size; mm++) + { + uom_save[half_size + index[iat] + mm] = occ_[iat][target_l][0][1].c[mm]; + } } } } From 8d7e74ff7d628a3bdfc2e6df744b3d72e31ac763 Mon Sep 17 00:00:00 2001 From: abacus_fixer Date: Tue, 1 Sep 2026 15:22:06 +0800 Subject: [PATCH 24/40] fix: adapt onsite_proj_force_stress.cpp to renamed Plus_U_Base interface Upstream PR #7873 split onsite_proj.cpp and introduced onsite_proj_force_stress.cpp, which still called the removed get_orbital_corr_data() (returning const int*).

C++14 requires at least one argument be passed for the ... parameter; omitting it is a C++20 extension that triggers -Wvariadic-macro-arguments-omitted under icpx -pedantic. Tensor::sync was the only call site in the whole codebase that omitted the second argument.
