From ae461ddcd69b583a9caf8935d1adcea9ba94e05a Mon Sep 17 00:00:00 2001 From: abacus_fixer Date: Fri, 16 Oct 2026 14:47:40 +0800 Subject: [PATCH 01/99] refactor(out_app_flag): change out_app_flag from bool to int and add unified output directories - Change out_app_flag from bool to int with three states: 0: no append, no subdirectory (overwrite) 1: append to same file (default, backward compatible) 2: write to unified subdirectories - Add new global directory variables in System_para: global_psi_dir, global_chg_dir, global_pot_dir, global_elf_dir, global_dos_dir, global_dip_dir, global_mat_dir - Initialize directories in set_global_dir(): out_app_flag==2 -> OUT.suffix/{PSI,CHG,POT,ELF,DOS,DIP,MAT}/ otherwise -> all point to global_out_dir (backward compatible) - Map legacy WFC->PSI, matrix->MAT - Update all out_app_flag usages from bool to int semantics - Broadcast new directory variables via Parallel_Common::bcast_string Issue: #8151 --- source/source_base/module_out/filename.cpp | 10 +++--- source/source_base/module_out/filename.h | 4 +-- .../source_io/module_ctrl/ctrl_output_fp.cpp | 2 +- .../source_io/module_ctrl/ctrl_scf_lcao.cpp | 12 +++---- source/source_io/module_dhs/write_dh.cpp | 6 ++-- source/source_io/module_dos/cal_dos.cpp | 4 +-- source/source_io/module_dos/cal_dos.h | 2 +- .../source_io/module_dos/write_dos_lcao.cpp | 6 ++-- source/source_io/module_dos/write_dos_lcao.h | 2 +- source/source_io/module_dos/write_dos_pw.cpp | 2 +- source/source_io/module_dos/write_dos_pw.h | 2 +- .../source_io/module_energy/write_bands.cpp | 4 +-- .../source_io/module_hs/dhs_sparse_writer.cpp | 6 ++-- .../source_io/module_hs/dhs_sparse_writer.h | 2 +- source/source_io/module_hs/hs_sparse_io.cpp | 2 +- source/source_io/module_hs/hs_sparse_io.h | 2 +- source/source_io/module_hs/hsk_writer.cpp | 6 ++-- source/source_io/module_hs/hsk_writer.h | 2 +- source/source_io/module_hs/hsr_legacy.cpp | 8 ++--- source/source_io/module_hs/hsr_legacy.h | 4 +-- source/source_io/module_hs/hterm_writer.cpp | 10 +++--- source/source_io/module_hs/hterm_writer.h | 2 +- .../source_io/module_hs/output_mat_sparse.cpp | 2 +- source/source_io/module_hs/pos_op_mat.cpp | 2 +- source/source_io/module_hs/pos_op_mat.h | 2 +- source/source_io/module_hs/pos_op_writer.cpp | 6 ++-- source/source_io/module_hs/pos_op_writer.h | 2 +- source/source_io/module_hs/vxc_op_lip.cpp | 2 +- source/source_io/module_hs/vxc_op_mat.cpp | 2 +- .../module_parameter/input_parameter.h | 5 +-- .../module_parameter/read_inp_out.cpp | 18 +++++++--- .../module_parameter/read_set_globalv.cpp | 36 +++++++++++++++++++ .../module_parameter/system_parameter.h | 10 +++++- source/source_io/module_wf/read_wf2rho_pw.cpp | 2 +- source/source_io/module_wf/read_wfc_nao.cpp | 2 +- source/source_io/module_wf/write_wfc_nao.cpp | 10 +++--- source/source_io/module_wf/write_wfc_nao.h | 2 +- source/source_io/module_wf/write_wfc_pw.cpp | 2 +- source/source_psi/psi_init_file.cpp | 2 +- 39 files changed, 131 insertions(+), 76 deletions(-) diff --git a/source/source_base/module_out/filename.cpp b/source/source_base/module_out/filename.cpp index 4dd86dc2bea..c7fa58fb9eb 100644 --- a/source/source_base/module_out/filename.cpp +++ b/source/source_base/module_out/filename.cpp @@ -14,7 +14,7 @@ std::string filename_output( const int nspin, const int nkstot, const int out_type, - const bool out_app_flag, + const int out_app_flag, const bool gamma_only, const int istep, const int iter) @@ -97,14 +97,14 @@ std::string filename_output( } std::string istep_block - = (istep >= 0 && (!out_app_flag)) + = (istep >= 0 && (out_app_flag != 1)) ?

Add a calculation parameter and open the stream with ios::app under the same condition as open_sparse_file (calculation=="md" && out_app_flag==1 && istep>=0), so each MD step appends a new record while other calculations start fresh. --- source/source_io/module_ctrl/ctrl_scf_lcao.cpp | 2 +- source/source_io/module_dm/test/write_dmk_test.cpp | 4 ++-- source/source_io/module_dm/write_dmk.cpp | 14 +++++++++++++- source/source_io/module_dm/write_dmk.h | 3 +++ 4 files changed, 19 insertions(+), 4 deletions(-) diff --git a/source/source_io/module_ctrl/ctrl_scf_lcao.cpp b/source/source_io/module_ctrl/ctrl_scf_lcao.cpp index 9ff021bf95f..e0dfe6d1667 100644 --- a/source/source_io/module_ctrl/ctrl_scf_lcao.cpp +++ b/source/source_io/module_ctrl/ctrl_scf_lcao.cpp @@ -197,7 +197,7 @@ void ModuleIO::ctrl_scf_lcao(UnitCell& ucell, } const int precision = inp.out_dmk[1]; - ModuleIO::write_dmk(dm->get_dmk_vec(), kv, precision, efermis, &(ucell), pv, global_mat_dir, istep, out_app_flag, ofs_running); + ModuleIO::write_dmk(dm->get_dmk_vec(), kv, precision, efermis, &(ucell), pv, global_mat_dir, istep, out_app_flag, inp.calculation, ofs_running); } //------------------------------------------------------------------ diff --git a/source/source_io/module_dm/test/write_dmk_test.cpp b/source/source_io/module_dm/test/write_dmk_test.cpp index 6b552788306..8990f4f68ed 100644 --- a/source/source_io/module_dm/test/write_dmk_test.cpp +++ b/source/source_io/module_dm/test/write_dmk_test.cpp @@ -165,8 +165,8 @@ TEST(DMKTest,WriteDMK) { kv.kd_done = true; std::ofstream ofs_log; - ModuleIO::write_dmk(dmk, kv, 3, efs, ucell, pv, out_dir, istep, 0, ofs_log); - ModuleIO::write_dmk(dmk_multik, kv, 3, efs, ucell, pv, out_dir, istep, 0, ofs_log); + ModuleIO::write_dmk(dmk, kv, 3, efs, ucell, pv, out_dir, istep, 0, "scf", ofs_log); + ModuleIO::write_dmk(dmk_multik, kv, 3, efs, ucell, pv, out_dir, istep, 0, "scf", ofs_log); std::ifstream ifs; diff --git a/source/source_io/module_dm/write_dmk.cpp b/source/source_io/module_dm/write_dmk.cpp index c57b8f196b9..e3774e213e4 100644 --- a/source/source_io/module_dm/write_dmk.cpp +++ b/source/source_io/module_dm/write_dmk.cpp @@ -189,6 +189,7 @@ void ModuleIO::write_dmk(const std::vector>& dmk, const std::string& dmk_dir, const int istep, const int out_app_flag, + const std::string& calculation, std::ofstream& ofs_running) { ModuleBase::TITLE("ModuleIO", "write_dmk"); @@ -198,6 +199,9 @@ void ModuleIO::write_dmk(const std::vector>& dmk, // so each ionic step overwrites the previous snapshot; the file body // still records the real ionic step via istep. const int istep_file = (out_app_flag == 1) ? -1 : istep; + // Each MD step appends a new record to the fixed file, mirroring the + // open_sparse_file convention; other calculations start fresh. + const bool append_on_restart = (calculation == "md") && (out_app_flag == 1) && (istep >= 0); int my_rank = 0; #ifdef __MPI @@ -247,7 +251,13 @@ void ModuleIO::write_dmk(const std::vector>& dmk, std::string fn = dmk_dir + dmk_gen_fname(gamma_only, ispin, nspin, ik, istep_file); - std::ofstream ofs(fn.c_str()); + std::ofstream ofs; + std::ios_base::openmode mode = std::ios::out; + if (append_on_restart) + { + mode |= std::ios::app; + } + ofs.open(fn.c_str(), mode); ofs << " --- Ionic Step " << istep+1 << " ---" << std::endl; @@ -354,6 +364,7 @@ template void ModuleIO::write_dmk(const std::vector> const std::string& dmk_dir, const int istep, const int out_app_flag, + const std::string& calculation, std::ofstream& ofs_running); template void ModuleIO::write_dmk>(const std::vector>>& dmk, @@ -365,5 +376,6 @@ template void ModuleIO::write_dmk>(const std::vector void write_dmk(const std::vector>& dmk, @@ -81,6 +83,7 @@ void write_dmk(const std::vector>& dmk, const std::string& dmk_dir, const int istep, const int out_app_flag, + const std::string& calculation, std::ofstream& ofs_running); } // namespace ModuleIO From a9cba384829f373b0ec25371f098e16a562c7961 Mon Sep 17 00:00:00 2001 From: abacus_fixer Date: Tue, 20 Oct 2026 14:39:03 +0800 Subject: [PATCH 22/99] docs(governance): require one-based ionic-step indices in outputs Rule 22: user-facing output files print ionic steps starting from 1, matching the g{N} filename suffix convention; zero-based counters such as "STEP: 0" are not allowed. --- AGENTS.md | 3 +++ 1 file changed, 3 insertions(+) diff --git a/AGENTS.md b/AGENTS.md index 0705adefe89..f235f134264 100644 --- a/AGENTS.md +++ b/AGENTS.md @@ -79,6 +79,9 @@ rules.

relax writes "# Ionic Step N" headers (one-based, governance rule 22) via the existing build_stru_header - mdcell::print_stru_file takes frame_comment + append; MD frames are prefixed with "# MD step N". The MPI path broadcasts a base offset (lseek SEEK_END) and keeps absolute pwrite offsets; O_APPEND is deliberately avoided since Linux pwrite ignores the offset with it - CIF output keeps single-frame semantics: fixed-name STRU.cif is overwritten each written step - modes 0/2 keep the numbered STRU{N} files unchanged - CLI help of out_stru/out_app_flag documents the mode-1 behavior Build: make -j 30 verified by developer. --- .../test/test_mdcell_reader.cpp | 2 +- source/source_cell/print_cell.cpp | 36 ++++++++++++++----- source/source_cell/print_cell.h | 20 +++++++++-- .../source_cell/test/read_atoms_hlp_test.cpp | 2 +- source/source_cell/test/test_print_cell.cpp | 18 +++++----- .../module_parameter/read_inp_out.cpp | 6 ++-- source/source_md/run_md.cpp | 15 ++++++-- source/source_relax/relax_driver.cpp | 17 ++++++--- source/source_relax/relax_stru_io.cpp | 6 ++-- source/source_relax/relax_stru_io.h | 5 ++- 10 files changed, 94 insertions(+), 33 deletions(-) diff --git a/source/source_cell/module_neighlist/test/test_mdcell_reader.cpp b/source/source_cell/module_neighlist/test/test_mdcell_reader.cpp index 50c907ab4f0..ac191c2d4cf 100644 --- a/source/source_cell/module_neighlist/test/test_mdcell_reader.cpp +++ b/source/source_cell/module_neighlist/test/test_mdcell_reader.cpp @@ -227,7 +227,7 @@ TEST(MDCellReaderTest, RestartStruPreservesAtomRecordsAcrossRanks) StruMeta metadata; metadata.species.resize(2); const std::string output_file = "distributed_mdcell_restart.STRU"; - mdcell::print_stru_file(mdcell, metadata, output_file); + mdcell::print_stru_file(mdcell, metadata, output_file, "", false); DomainDecomposition reader_decomp; MDCell round_trip = MDCellReader::read_stru(output_file, diff --git a/source/source_cell/print_cell.cpp b/source/source_cell/print_cell.cpp index f98b3ab8a99..2697bd1a961 100644 --- a/source/source_cell/print_cell.cpp +++ b/source/source_cell/print_cell.cpp @@ -101,7 +101,8 @@ namespace unitcell const bool& dpks_desc, const int& iproc, const ModuleBase::matrix& force, - const bool& has_force) + const bool& has_force, + const bool append) { ModuleBase::TITLE("UnitCell","print_stru_file"); if (iproc != 0) @@ -235,7 +236,12 @@ namespace unitcell nat_++; } } - std::ofstream ofs(fn.c_str()); + std::ios_base::openmode mode = std::ios::out; + if (append) + { + mode |= std::ios::app; + } + std::ofstream ofs(fn.c_str(), mode); ofs << str; ofs.close(); return; @@ -368,7 +374,8 @@ StruMeta make_stru_meta(const UnitCell& ucell) namespace mdcell { -void print_stru_file(const MDCell& cell, const StruMeta& stru_meta, const std::string& fn) +void print_stru_file(const MDCell& cell, const StruMeta& stru_meta, const std::string& fn, + const std::string& frame_comment, const bool append) { if (stru_meta.species.size() != cell.type_labels().size() || stru_meta.species.size() != cell.type_masses().size() @@ -376,27 +383,35 @@ void print_stru_file(const MDCell& cell, const StruMeta& stru_meta, const std::s { throw std::runtime_error("MDCell STRU metadata does not match the MDCell type data."); } - const std::string header = mdcell_stru_header(cell, stru_meta); + const std::string header = frame_comment + mdcell_stru_header(cell, stru_meta); #ifdef __MPI int rank = 0; const MPI_Comm comm = cell.communicator(); MPI_Comm_rank(comm, &rank); int header_ok = 1; + MPI_Offset base_offset = 0; if (rank == 0) { - const int header_file = open(fn.c_str(), O_CREAT | O_TRUNC | O_WRONLY, 0666); + // No O_APPEND: on Linux pwrite() ignores the given offset when the + // file was opened with O_APPEND.

Empty the availability expression so the flag is visible to every run type. The lcao restriction was never enforced in the code paths and PW users were only being hidden from the parameter — the PW writers above now back that description up. --- source/source_io/module_ctrl/ctrl_output_pw.cpp | 4 ++-- source/source_io/module_parameter/read_inp_out.cpp | 5 ++++- 2 files changed, 6 insertions(+), 3 deletions(-) diff --git a/source/source_io/module_ctrl/ctrl_output_pw.cpp b/source/source_io/module_ctrl/ctrl_output_pw.cpp index 5bffea81abe..7b8baff6f86 100644 --- a/source/source_io/module_ctrl/ctrl_output_pw.cpp +++ b/source/source_io/module_ctrl/ctrl_output_pw.cpp @@ -189,14 +189,14 @@ void ModuleIO::ctrl_scf_pw(const int istep, // Use the solver's native wavefunction precision for FFT and projector overlaps.

This test drives out_app_flag=2 for istep=0, swaps the FakeHamilt payload, writes again, and verifies the second payload replaced the first.

The dipole data line was written to 'ofs' on every rank, but the file is only opened on rank 0. Non-root ranks wrote to an unopened stream, which is undefined behaviour and corrupts output when it doesn't crash outright.

The asserts in write_elf rejected that legitimate empty partition. Dropping the asserts alone is not enough if the FFT body is skipped: real2recip/recip2real go through PW_Basis::gatherp_scatters, which performs an MPI_Alltoallv that requires every rank in POOL_WORLD to participate, so a rank that returns early deadlocks the grid-owning ranks inside Alltoallv. Run the same FFT path unconditionally on every rank (the per-grid-point loops simply iterate zero times when nrxx == 0) and keep every rank in the write_vdata_palgrid output section for the collective MPI_Gatherv in Parallel_Grid::reduce. Add regression tests for the zero-length container and zero-iteration invariants. Verified with examples/17_relax/04_relax_with_output_lcao (out_elf 1): OMP_NUM_THREADS=4 mpirun -np 4 abacus_max_para finishes in 4 s and writes elfs1.cube, elfs2.cube and elftot.cube; MODULE_IO_write_elf_logic_test passes 14/14.

Text outputs already append records under the same flag, and out_wfc_lcao already truncates on the first step and appends afterwards, so cube output was the remaining inconsistency. Pass an explicit append flag down the writer chain instead of reading PARAM inside the writers: - write_cube / write_vdata_palgrid take a new append parameter and open the file with std::ios::app when it is set, otherwise truncate; - write_elf and write_elecstat_pot forward it, and write_chg_init / write_pot_init compute it from inp.out_app_flag; - ctrl_output_fp uses append = (out_app_flag == 1 && istep > 0), mirroring the out_wfc_lcao rule: the first written ionic step truncates, later written steps append one complete frame whose first comment line is Ionic_Step {#}, one-based. Single-point SCF/NSCF stays at istep == 0, so it keeps overwriting rather than stacking on a stale file from a rerun. - every other call site (LDOS, LCAO/PW wavefunction cubes, partial charge, LR-TDDFT density, exciton density, DM2rho) passes false explicitly to keep its existing truncate behaviour. Update the out_app_flag and out_elf help text, the output specification, and add CubeIOTest.WriteCubeAppendFrames covering truncate-then-append-then- truncate frame counting and the trailing newline contract.

Verification: - Grouped and applied via patch-based hunk split (backup in /tmp/commit_split_backup).

Fix the docs to describe the actual k-space output, and rename the parameters to match the established *k suffix convention. - Doc fix: out_mat_h_t/vnl/vl/vh/vxc/exx descriptions now state k-space NAO text output instead of the bogus "R in CSR format". - out_mat_h_t is a legacy alias of out_mat_tk (the dedicated write_h_t path duplicated the T(k) output and is removed). - Rename: out_mat_h_vnl->out_mat_vnlk, out_mat_h_vl->out_mat_vlk, out_mat_h_vh->out_mat_vhk, out_mat_h_vxc->out_mat_vxck, out_mat_h_exx->out_mat_exxk. Old names remain as legacy aliases resolved during input normalization (new name wins; legacy value maps over). - Update MAT/ directory creation condition and ctrl_scf_lcao to the new canonical names. - Add HkComponentAliases serial test covering alias mapping and new-name-wins priority. Verification: compiled with make -j 30; HkComponentAliases, HsOutputAliases and the full MODULE_IO ctest label (54 tests) pass; code_quality_score is unchanged from the pre-change baseline (remaining debt is pre-existing). --- .../source_io/module_ctrl/ctrl_scf_lcao.cpp | 21 +- source/source_io/module_hs/hterm_writer.cpp | 28 +-- source/source_io/module_hs/hterm_writer.h | 6 +- .../module_parameter/input_parameter.h | 17 +- .../module_parameter/read_inp_out.cpp | 204 ++++++++++++++---- .../source_io/module_parameter/read_input.cpp | 35 ++- .../test_serial/read_input_item_test.cpp | 60 ++++++ 7 files changed, 284 insertions(+), 87 deletions(-) diff --git a/source/source_io/module_ctrl/ctrl_scf_lcao.cpp b/source/source_io/module_ctrl/ctrl_scf_lcao.cpp index 0ee884ec369..132fd428433 100644 --- a/source/source_io/module_ctrl/ctrl_scf_lcao.cpp +++ b/source/source_io/module_ctrl/ctrl_scf_lcao.cpp @@ -53,8 +53,8 @@ void setup_exx_h_params(ModuleIO::WriteHParams& h_params, Exx_NAO& exx_nao, // EXX-H output is unsupported.

Since that file is always read from its first frame, a positive restart index (istep >= 0) would silently load step-0 wave functions whenever the step-suffixed file was missing, corrupting the TDDFT restart without any error. Restrict the cumulative-file candidate to istep < 0 (first read) so a positive restart that cannot find its step-suffixed snapshot now fails loudly through the existing error path instead of reading the wrong frame. Add a unit test (ReadWfcNaoTest.PositiveStepRejectsCumulativeFile) that writes only the cumulative file and asserts that a positive-step read fails. Not yet compiled or run; build and test verification pending. --- source/source_io/module_wf/read_wfc_nao.cpp | 31 +++++---- source/source_io/test/read_wfc_nao_test.cpp | 75 +++++++++++++++++++++ 2 files changed, 93 insertions(+), 13 deletions(-) diff --git a/source/source_io/module_wf/read_wfc_nao.cpp b/source/source_io/module_wf/read_wfc_nao.cpp index d0fe553bd32..310a9e7b3d0 100644 --- a/source/source_io/module_wf/read_wfc_nao.cpp +++ b/source/source_io/module_wf/read_wfc_nao.cpp @@ -435,7 +435,9 @@ bool ModuleIO::read_wfc_nao( // 3. readin_dir + "WFC/" + step-suffixed name: layout written by // releases before the out_app_flag rework // 4. readin_dir + name without the step suffix: written in append - // mode (out_app_flag 1) + // mode (out_app_flag 1); only valid for istep < 0, because the + // cumulative file is always read from its first frame and would + // silently return step-0 data for a positive restart index std::vector candidates; if (istep >= 0) { @@ -476,18 +478,21 @@ bool ModuleIO::read_wfc_nao( gamma_only, istep)); } - const int append_app_flag = 1; - candidates.push_back(ModuleIO::filename_output(global_readin_dir, - "wf", - "nao", - ik, - ik2iktot, - nspin, - nkstot, - read_type, - append_app_flag, - gamma_only, - istep)); + else + { + const int append_app_flag = 1; + candidates.push_back(ModuleIO::filename_output(global_readin_dir, + "wf", + "nao", + ik, + ik2iktot, + nspin, + nkstot, + read_type, + append_app_flag, + gamma_only, + istep)); + } for (size_t ic = 0; ic < candidates.size(); ++ic) { diff --git a/source/source_io/test/read_wfc_nao_test.cpp b/source/source_io/test/read_wfc_nao_test.cpp index 8c0b9bbb18a..5e730352baf 100644 --- a/source/source_io/test/read_wfc_nao_test.cpp +++ b/source/source_io/test/read_wfc_nao_test.cpp @@ -729,6 +729,81 @@ TEST_F(ReadWfcNaoTest, CompleteGlobalKPointPopulations) } } +TEST_F(ReadWfcNaoTest, PositiveStepRejectsCumulativeFile) +{ + // A positive restart step must not fall back to the fixed-name cumulative + // file (out_app_flag == 1): that file is always read from its first frame, + // so accepting it would silently return step-0 data for a later step.

Pass the global step index (step_ + step_rst_) to force_virial in both md_base.cpp and run_md.cpp so restarted runs emit a non-zero step and append correctly. Also restructure the STRU output decision in run_md.cpp: separate the fixed-name selection from the append/truncate decision. A fresh run's first frame truncates the fixed-name STRU; later steps and all restarted frames append.

The cumulative STRU is now preferred when its last "# MD step N" marker matches istep + 1; the numbered legacy names remain as fallbacks.

Mode semantics: - 0 (default): fixed filename, truncated and overwritten at every write - 1: fixed filename, text records / cube frames are appended (first written step truncates so reruns do not keep stale frames) - 2: subdirectory + per-step g{step} file (one-based step index) Naming and open mode are decoupled across all writers: the g{step} suffix is only inserted when out_app_flag == 2, and an explicit append flag (true only for mode 1 and istep > 0) controls whether the file is opened in append or truncate mode. Covers cube/charge/potential/elf, DOS/PDOS, DM(R)/DM(k), H(R)/S(R), H(k)/S(k), T/R/dH, position/angular-momentum operators, PW/LCAO wave functions, and relax structure output. --- source/source_base/module_out/filename.cpp | 8 +-- source/source_base/module_out/filename.h | 9 ++-- source/source_estate/write_init.cpp | 18 +++---- .../source_io/module_ctrl/ctrl_output_fp.cpp | 10 ++-- .../source_io/module_ctrl/ctrl_scf_lcao.cpp | 17 +++--- source/source_io/module_dhs/write_dh.cpp | 9 ++-- source/source_io/module_dm/write_dmk.cpp | 8 +-- source/source_io/module_dm/write_dmr.cpp | 29 +++++++---- source/source_io/module_dm/write_dmr.h | 21 ++++---- .../source_io/module_dos/write_dos_lcao.cpp | 6 +-- source/source_io/module_dos/write_dos_pw.cpp | 6 +-- .../source_io/module_dos/write_pdos_text.cpp | 7 +-- source/source_io/module_hs/angmom_op_mat.cpp | 9 ++-- .../source_io/module_hs/dhs_sparse_writer.cpp | 8 +-- source/source_io/module_hs/hsr_legacy.cpp | 6 +-- source/source_io/module_hs/hsr_writer.cpp | 52 +++++++++++-------- source/source_io/module_hs/hsr_writer.h | 17 +++--- source/source_io/module_hs/hterm_writer.cpp | 15 +++--- source/source_io/module_hs/pos_op_writer.cpp | 6 +-- .../module_parameter/input_parameter.h | 5 +- source/source_io/module_wf/read_wf2rho_pw.cpp | 2 +- source/source_io/module_wf/read_wfc_nao.cpp | 18 ++++--- source/source_relax/relax_driver.cpp | 9 ++-- 23 files changed, 165 insertions(+), 130 deletions(-) diff --git a/source/source_base/module_out/filename.cpp b/source/source_base/module_out/filename.cpp index 17b9f4c3167..3f1b464ca03 100644 --- a/source/source_base/module_out/filename.cpp +++ b/source/source_base/module_out/filename.cpp @@ -101,14 +101,14 @@ std::string filename_output( } std::string istep_block - = (istep >= 0 && (out_app_flag != 1)) + = (istep >= 0 && (out_app_flag == 2)) ?

Previously, with out_freq_ion > 0 and a small out_freq_elec, every electronic iteration within a step targeted the same file: at istep 0 each iteration truncated (only the last survived), while at istep > 0 each iteration appended another frame. This produced an inconsistent trajectory (one frame for step 0, N frames for later steps). Now in mode 1 ctrl_iter_pw ignores out_freq_elec and only writes the last electronic iteration (iter == scf_nmax, converged, or final_output) of each ionic step selected by out_freq_ion, so the appended file holds exactly one frame per step. Modes 0 and 2 keep the out_freq_elec intermediate-iteration behavior unchanged. LCAO wfc output is unaffected because ctrl_scf_lcao runs once per ionic step (after SCF) and does not gate on out_freq_elec.

The old predicate had to enumerate every writer's flags by hand and was patched in three separate review rounds; moving creation to the writers removes that whole class of drift. Each ensure sits inside the existing output flag guard, so only directories that actually receive a file are created. Writers that read `PARAM.globalv.*_dir` directly (write_dh_perI, write_wfc_nao, output_mat_sparse) ensure in the leaf; dispatcher-level sites hoist the directory into a local so the ensure and the write share one lookup. --- source/source_base/fs_compat.h | 24 +++++++++ source/source_esolver/esolver_gets.cpp | 12 +++-- source/source_esolver/esolver_ks_lcaopw.cpp | 6 ++- .../source_io/module_ctrl/ctrl_output_fp.cpp | 11 ++++ .../source_io/module_ctrl/ctrl_output_pw.cpp | 26 ++++++++-- .../module_ctrl/ctrl_runner_lcao.cpp | 20 ++++++-- .../source_io/module_ctrl/ctrl_scf_lcao.cpp | 34 ++++++++++++- source/source_io/module_dhs/write_dh.cpp | 4 ++ .../source_io/module_hs/output_mat_sparse.cpp | 8 +++ .../source_io/module_parameter/read_input.cpp | 51 +++---------------- source/source_io/module_wf/write_wfc_nao.cpp | 4 ++ source/source_md/run_md.cpp | 3 ++ source/source_relax/relax_driver.cpp | 5 ++ 13 files changed, 150 insertions(+), 58 deletions(-) diff --git a/source/source_base/fs_compat.h b/source/source_base/fs_compat.h index 3e3a58e0dca..4ad1c0054c2 100644 --- a/source/source_base/fs_compat.h +++ b/source/source_base/fs_compat.h @@ -43,6 +43,30 @@ inline int make_directory(const std::string& path) #endif } +/** + * @brief Ensure a directory exists, creating it lazily if needed. + * + * Intended for write-time directory creation: output writers call this just + * before writing a file into a directory that may not exist yet, instead of + * relying on a central startup routine to predict which directories will be + * needed.
