Toast-- Development History

v0.9.0

Initial release:

  • MATLAB interface compatible with Toast++ 2.0.2
  • Python interface unstable

Development from Toast++

  • Bump liblbfgs to master for CMake support
  • Add Eigen
  • Remove LU decomposition from TCompRowMatrix, implementation (crmatrix.cc) removed from build and decleration commented, remove SuperLU headers from crmatrix_cm.cc.
  • Implement CMakeLists.txt for libmath, libstoast, libfdot, matlab MEX
  • Add #define FELIB_IMPLEMENTATION to wdg18inf.cc for proper symbol import/export on Windows
  • Implement libfe CMakeLists.txt for default build without options
  • Remove complex SuperLU solver engines from build (fwdsolver_*slu.cc), and exclude headers
  • Replace functionalisty of SuperLU solver engines with Eigen templated LU
  • Fix headers that do not actually require SuperLU
  • Provide interface headers for subprojects, pick up headers automatically
  • Fix gitignore exclusion of liblbfgs and Eigen and reimport
  • Fixup nr.cc for MacOS Clang by removing definition of vector and using dvector instead
  • Need explicit instantiation required on MacOS
  • Standard CXX 98 required for MacOS (owing to narrowing in matlab interface) which requires spacing on double template args
  • Implement CMakeLists.txt for all bintools targets
  • Enable explicit instantiation in fwdsolver_mw.h (linux build failed with this, perhaps this could be a Clang thing, added to TODO)
  • Add STOASTLIB (dll import/export) to MWsolution class
  • Implement CMakeLists.txt for all buildable supertoast targets (NB: some Makefile targets no longer exist or reference old code)
  • Purge unused numerics, configuration, projects
  • Purge MPI support
  • Purge CUDA support
  • Cleanup core headers
    • Make all defines check for _WIN32 not WIN32, remove setting from CMake
    • Remove unused TOASTLIB define
    • Remove expiry functions (not used) and defines
    • Remove USE_SPLBLAS (unued)
  • Python interface development
    • Complete refactor of python build with view to CI builds of wheels
    • CMake target configures a setuptools script with full paths, installs dynamic and import libraries in the tree for automatic installation
    • CMake install target provides a tree that can be built using python -m pip wheel or python -m build or python setup.py bdist_wheel. The former are isolated builds.
    • Update all reconstruction scripts, noting
      • (silent) errors when basis mapping input are not rank-1
      • Jacobians take handles to bases, rathter than just taking the basis
      • Arugement checking throughout module
      • Move from np.matrix to np.ndarray through module and in examples
      • Reorganise examples
  • Clean up part two
    • Refactor headers
    • Remove unused eigpair.cc, arpack.cc, crmatric.cc (LU)
    • Python interface integer refactor
  • Refactor raster out of libstoast and into its own module (libraster)
  • Provide for static build of libraries to output single mex and toast modules without dependency 'challenges'
  • Multithreading
    • Rework coarse parallelism to use C++ threads
    • Enable TOAST_THREAD at THREAD_LEVEL_2 by default, providing parallel assembly, source/meas construction, some Jacobian calculations, iterative solvers over QM
    • Remove THREAD_LEVEL_1 (which uses the thread pool, not ported), and make THREAD_LEVEL_2 == TOAST_THREAD, remove vector_MT.
    • Enable multi-threading in Python interface
    • Thread pool based parallelism removed as used in limited places. Will consider reimplementation with OpenMP or standard library implementation: TOAST_PARALLEL define, parallel CG implementation, thread pool implementation.
  • Refactor Python build configuration to be standalone, and run from the source root, in order to use cibuildwheel in CI
  • Enale CI for Python wheels and MATLAB mex builds
  • Remove remaining MESA based functionality
  • Remove mesh reordering functionality due to LGPL license
  • Remove ILUPACK bindings
  • Remove unused solver implementations
  • Fix swap bug with internal Cholesky implementation, use Eigen Cholesky for forward solvers
  • Split factorise/analyse steps in forward solver
  • toastFields reimplemented with both MATLAB and TOAST solvers, the former used by default for direct solves
  • toastJacobianCW reimplemented to use toastFields
  • toastJacobianCW mesh integrals multithreaded, 6x speedup on 8x threads
  • Update MEX interface to interleaved complex (>R2018a) format with runtime improvements
  • Remove old MATLAB interface scripts
  • Cache sparsity structure inside mesh
  • Use C++ stdlib parallel sort for sparsity structure computation
  • Compound matrix assembly works over all parameters at once, reducing time for local summation
  • Make single precision (for CUDA) and the new raster interface optional compile time defines
