Changelog

Current - Version 0.3.1

  • Added updating main diagonal of sparse matrix in MatrixOperations. Update is only performed on non-zero elements of the main diagonal i.e doesn't change the sparsity pattern of the matrix.
  • Added interface to inspect the sparse formats using their enum tag and facilitate format switching for dynamic matrix.
  • Fixed errors in deep copy semantics for the DynamicMatrix.
  • Added command line parsing for selecting dynamically which format to switch to.
  • Added execution space trait in containers so that any member functions will use those for determining where to be executed.

Version 0.3.0

  • Build morpheus as a package with different subpackages.
  • Enabled test environment for the core functionality using googletest framework.
  • Enabled GPU support through the Host-Device model.
  • Support for container mirroring through create_mirror and create_mirror_container as well as HostMirror trait.
  • Efficient deep copies for containers across same/different memory spaces through the Morpheus::copy routine.
  • Added Dot and WAXPBY alogirhtms for DenseVector.
  • Added Reduction and Scan routines for DenseVector.
  • Added convert algorithms for conversion across different containers on Host space.
  • Algorithm dispatch through Kokkos::Serial, Kokkos::OpenMP and Kokkos::Cuda for the custom kernels.
  • Added Morpheus::Serial, Morpheus::OpenMP and Morpheus::Cuda to be used for dispatching Kokkos kernels in algorithms.
  • SpMV implementation for CooMatrix, CsrMatrix and DiaMatrix available for Kokkos::Serial, Kokkos::OpenMP, Kokkos::Cuda and Kokkos equivalent spaces - except for currently the Kokkos implementation for CooMatrix.
  • Enabled shallow copy semantics between DynamicMatrix and concrete containers based on the active type of the DynamicMatrix.
  • Enabled mirroring and deep copy semantics for the DynamicMatrix.

Version 0.2.0

  • Introduces DynamicMatrix container, a polymorphic container that holds a closed set of Sparse Matrix Storage Formats.
  • Use of variadic templates to create a uniform interface under DynamicMatrix container for operations like resize(), which for different formats can have a different signature.
  • Use of metaprogramming techniques for generalising the run-time switching across formats.
  • Use of metaprogramming techniques to examine the traits of a vector and matrix.
  • Added implementation of DenseVector and DenseMatrix
  • Added implementation of CooMatrix, CsrMatrix and DiaMatrix.
  • Kokkos integration to use the different memory and execution spaces.
  • Interface for dispatching multiply and print operations using tag dispatching to distinguish amonst formats.
  • Extended interface to dispatch operations to different architectures using SFINAE. Each container should reside in the same execution space.
