    • Solver update · 2ab39862
      Added multilevel version of crout-ilu solver with maximum product
      transversal preordering on each level. The multilevel version is based
      on condition number estimation, factorization of rows with large
      condition number or small diagonal is postponed for the next level.
      
      Fixes for near-zero values in maximum product transversal algorithm and
      negative path-length.
      
      Fixes for output in DrawMatrix, option for text-based output for small
      matrices.

    • Synchronize · 635cc476
      Cleanup of Row class and Matrix class.
      
      Significantly reduced memory required for Row class and consequently for
      multivar_expression class. Moved out openmp locks and row annotation as
      additional service classes.
      
      Introduced classes HessianRow and HessianMatrix for future possibility
      of hessian computation in automatic differentiation.

    • Added functionality and fixed issues. · 50d10e74
      Fixes for GCC.
      
      Moved functionality to operate with dense matrices as INMOST service.
      
      Added possibility to exchange data of type DATA_VARIABLE in parallel.
      
      Added possibility to include external content in xml format.
      
      Moved overloaded operators for variables from namespace INMOST into
      global scope to prevent possible ambiguities in compilers.
      
      Added perturbation algorithm for BCGS solver.

      Added 2-clause bsd license for cmake files requested in cmake script for
      petsc.
      Introduced cmake option for Mondriaan matrix partitioning package for
      solvers.
      Changed reading of solver's parameters database to fix uninitialized
      access reported by dr.memory.
      Fixed bug in svdnxn with static std::vector allocation.
      Added features to OldDrawGrid example.
      Added solutions to problems described in issue #13.

      Fixed bug in auto-differentiation that would calculate incorrect weights
      for derivatives in ad_val().
      Adapted several geometrical and adjacency retrieval algorithms to handle
      broken conformity of the grid during modification, more attention to the
      problem is needed.
      Added visual studio debugger helpers.
      Fixed several issues with openmp support.
      Added openmp parallelization of BiCGStab(L) solver.
      Fixed issues that files overwritten with MPI_File* functionality may
      contain previous information.
      Fixed a bug in OctreeCutcell, added another example for it.
      Fixed a bug in collective operations in mesh class.

      Activated checking for cell duplication by default to cure problem when
      loading distributed meshes with ghost cells on same processor.
      Fixed problem that vtk reader may delete some nodes that were there
      previously.
      Removed possibility to pass parameters directly to internal solvers
      through Solver::SetParameter* since they are overwritten later.
      Added but not yet activated solver_test001.
