0.8.7 Release Highlights

(adapted from Conduit's Changelog)

Added

General

  • Added public default and copy constructor to DataAccessor. Enables more flexibility with initializing DataAccessors from Nodes.
  • Added Node.name(), Node.path(), Schema.name(), and Schema.path() to Python API.
  • Added Node.as_index_t_ptr()
  • Added conduit::execution namespace, which contains for_all() and sort() functions.
  • Added DataType support to the Fortran API

Blueprint

  • Added conduit::blueprint::mpi::mesh::distribute, which enables sending mesh domains to arbitrary MPI ranks (suppo
  • Added conduit::blueprint::mesh::utils::NDIndex class. Instantiate with shape, offset, and stride in array or conduit::Node. Get flatindex for N-D coordinates.
  • Added conduit::blueprint::o2mrelation::O2MIndex class. Instantiate with O2M relation Node; get flatindex for a given one_index and many_index. Alternative to Java-style iterator.
  • Added conduit::blueprint::examples::mesh::rz_cylinder function that generates example 2D cylindrical (RZ) meshes.

Fixed

General

  • Fixed a logic issue undermining C++ type mapping when using CMake 3.26.

Blueprint

  • Performance improvements to Mesh Blueprint topology metadata, used by generate_points, generate_sides, etc. The class was rewritten and the old one was moved to conduit::blueprint::mesh::utils::reference::TopologyMetadata. The new implementation is faster, often about 6-20x depending on options.
  • Performance improvements to O2M Iterators.
  • Performance improvements to functions that underpin centroid generation.

Relay

  • Fixed MPI baton logic error in conduit::relay::io::blueprint::save_mesh() that caused MPI tasks to serialize writes to files in the N domains to M files case. Fix restores parallel write performance. This bug did not impact cases where where N domains were written to N files (N to N) or N domains were written to a single file (N to 1).

Changed

General

  • Changed diff of string types to respect null terminated strings instead of described length
  • Improved diff_compatible of string types to look for substring match, to implement expected compatible semantics.

Blueprint

  • Changed the recommended axis order for 2D cylindrical meshes to be Z as the first axis, and R as the second. This choice aligns with expected visualization cases where Z varies with the horizontal axis and R varies with the vertical axis.
