Changelog

All notable changes to this project will be documented in this file.

Unreleased

Added

  • set_delay_dense_computation to HMatrix

Changed

Fixed

  • Fix const-correctness for g++ 4.8.5

[0.8.1] - 2023-05-26

Added

  • set_delay_dense_computation to HMatrix
  • clustering with user partition requiring permutation

Changed

  • improved CI with stricter flags
  • moved version number definition from misc/define.hpp to htool_version.hpp

Fixed

  • Fix const-correctness for g++ 4.8.5
  • Fix compatibility with c++20
  • Fix MPI data type for complex float and double
  • Fix issue with default MPI communicator

[0.8] - 2022-01-27

Added

  • doxygen documentation
  • mvprod_transp_global_to_global and mvprod_transp_local_to_local added to VirtualHMatrix
  • getters for clusters in VirtualHMatrix
  • custom gmv in ddm

Changed

Fixed

  • Corner case with ACA resolved (first row/column only contains zeroes)
  • Warnings from fujitsu compilers because of last line
  • bug when using threading in mvprod

[0.7] - 2021-09-21

Added

  • CMakefile checks consistency of version number across git/c++/CMake
  • Test for warnings coming from include/htool/*
  • Coverage added
  • Methods in ddm interface to get local numbering
  • VirtualLowRankGenerator and VirtualAdmissibilityCondition added for better modularity

Changed

  • Remove unnecessary arguments in HMatrix and cluster interfaces
  • MutliHMatrix deprecated for the moment (everything related to this in htool/multi)

Fixed

  • Missing inlines added
  • Fix bug when using htool via petsc with mkl

[0.6] - 2021-08-03

Changed

  • Python interface with ctypes deprecated, see new python interface with pybind11.
  • Performance tests removed, see dedicated repository.
  • GUI deprecated.

[0.5] - 2021-08-03

Added

  • Interface for clustering via VirtualCluster, implementation with Cluster whose template parameter is the type of clustering (supported now: PCARegularClustering, PCAGeometricClustering, BoundingBox1RegularClustering and BoundingBoxGeometricClustering).
  • Interface for hmatrix objects via VirtualHMatrix, implementation with HMatrix whose template parameter is the type of compressor (supported now: SVD, fullACA, partialACA, sympartialACA, all derived from abstract class LowRankMatrix).
  • Interface for generator via VirtualGenerator. The user needs to define an object deriving from VirtualGenerator to populate a hmatrix.
  • Block class with different admissible condition used in Block (only RjasanowSteinbach at the moment).
  • Interface for a sub-block via IMatrix, from which both SubMatrix and LowRankMatrix inherit. They respectively correspond to dense and compressed sub-blocks.
  • DDM solvers via HPDDM, and coarse space building.
  • Test suite and CI with GitHub action.
