From edb37985d51400303b5bc2c4ed7e16925d96d761 Mon Sep 17 00:00:00 2001 From: AroundPeking Date: Sat, 17 Oct 2026 23:03:49 +0800 Subject: [PATCH 1/8] feat(exx): Ewald Coulomb input parameters and Exx_Info_RI fields for strict-2D RI-EXX Add the strict-2D/3D Ewald Coulomb controls (ewald dimension, lambda, tail check mode with tolerances and adaptive expansion limits, direct mixed-Fourier 2D and reciprocal 3D Coulomb output selection with quadrature orders, RPA ABFS preorthogonalization, EXX V-matrix screening thresholds) to the input parameters, wire them through the EXX reading path, and extend Exx_Info_RI and the XC functional type so downstream RI modules can consume them. read_input unit tests cover the new keywords. --- source/source_hamilt/module_xc/exx_info.cpp | 12 + source/source_hamilt/module_xc/exx_info_ri.h | 12 + .../source_hamilt/module_xc/xc_functional.cpp | 21 ++ .../source_hamilt/module_xc/xc_functional.h | 3 + .../module_parameter/input_parameter.h | 21 ++ .../module_parameter/read_inp_exx_dftu.cpp | 220 ++++++++++++++++++ .../module_parameter/read_inp_out.cpp | 181 +++++++++++++- source/source_io/test/read_input_ptest.cpp | 10 + source/source_io/test/support/INPUT | 10 + .../test_serial/read_input_item_test.cpp | 103 ++++++++ 10 files changed, 590 insertions(+), 3 deletions(-) diff --git a/source/source_hamilt/module_xc/exx_info.cpp b/source/source_hamilt/module_xc/exx_info.cpp index 7098c1dd7d5..4887d7fb366 100644 --- a/source/source_hamilt/module_xc/exx_info.cpp +++ b/source/source_hamilt/module_xc/exx_info.cpp @@ -221,12 +221,24 @@ bool init_exx_info(Exx_Info& exx_info, const Input_para& inp) exx_info.info_ri.pca_threshold = inp.exx_pca_threshold;

Restore the empty-abfs construction branch in Exx_LRI::init_spencer that the signature unification dropped. The tail completeness check now bounds the projected Gaussian tensor by the RI integral pipeline's own support min(cal_V_Rcut) instead of the raw gaussianized-aux radius sum, which demanded identically-zero blocks and failed coverage in warn mode. Evaluate wigner_d factorials in double so high-L (l>=5) rotation matrices no longer overflow int and produce NaN. Wire the EXX LCAO operator, LR-TDDFT esolver, RDMFT, and center2orbital paths to the extended interfaces, and add unit tests for the kernels, tail utilities, and symmetry rotation. ---

Extend check_librpa_producer.py with the strict_2d_head kind and its self-test. Regenerate the Ewald far-field coulomb_mat references of rpa_scf_gamma and rpa_scf_shrink_multik for the ported tail machinery (energies unchanged to 4e-13 eV). ---

From: AroundPeking Date: Sun, 18 Oct 2026 21:52:52 +0800 Subject: [PATCH 5/8] docs(ri): key-formula comments for the strict-2D Coulomb and Ewald tail sources Comment the construction the ported kernels implement: the positive Gram quadrature of the direct mixed-Fourier route (the tan-mapped kz rule and the Massidda-constrained Gamma plane), the analytic 2D Gaussian compensation integrals, the Ewald tail planner decision table, the Gaussian decay exponent search, and the strict-2D head normalization. The new sources carried essentially no comments, repeating the review finding from the reader-v1 producer PR. Also drop the INTERFACE OpenMP link added to the device object library during the port: this PR's OpenMP usage lives in the module_ri targets, and develop links the same device objects without publishing OpenMP, so the hunk was unrelated to this PR's scope. --- source/CMakeLists.txt | 5 -- .../module_ri/direct_2d_coulomb.cpp | 48 +++++++++++++++++++ .../source_lcao/module_ri/direct_2d_coulomb.h | 13 +++++ .../module_ri/direct_2d_coulomb_ewald.hpp | 7 +++ .../module_ri/direct_3d_coulomb_ewald.hpp | 6 +++ .../module_ri/ewald_gaussian_cutoff.h | 9 ++++ .../source_lcao/module_ri/ewald_tail_utils.h | 33 +++++++++++++ .../module_ri/gaussian_abfs_2d_integrals.h | 26 ++++++++++ .../module_librpa_io/librpa_2d_coulomb_head.h | 10 ++++ 9 files changed, 152 insertions(+), 5 deletions(-) diff --git a/source/CMakeLists.txt b/source/CMakeLists.txt index 0ac98723b29..f613fbe3e01 100644 --- a/source/CMakeLists.txt +++ b/source/CMakeLists.txt @@ -706,11 +706,6 @@ endif() add_library(device OBJECT ${device_srcs}) -# Device object files use OpenMP and must publish its runtime to consumers. -if(ENABLE_OPENMP) - target_link_libraries(device INTERFACE OpenMP::OpenMP_CXX) -endif() - if(USE_CUDA) target_link_libraries(device PRIVATE cusolver cublas cufft) elseif(USE_ROCM) diff --git a/source/source_lcao/module_ri/direct_2d_coulomb.cpp b/source/source_lcao/module_ri/direct_2d_coulomb.cpp index 0a91f01159b..952fb95b699 100644 --- a/source/source_lcao/module_ri/direct_2d_coulomb.cpp +++ b/source/source_lcao/module_ri/direct_2d_coulomb.cpp @@ -13,6 +13,25 @@ #include #include +// Direct mixed-Fourier construction of the strict-2D full Coulomb matrix. +// +// The established Ewald route builds V as (real space) - (Gaussian +// compensation) + (reciprocal) + (tail), several large terms whose difference +// is the small physical matrix; imperfect cancellation can then leave a +// strongly indefinite result for diffuse or high-l auxiliary functions.
