0.9.3 Release Highlights

(adapted from Conduit's Changelog )

Released 2025-01-27

Added

Conduit

  • Added conduit_yaml and conduit_base64_yaml protocol support.
  • Added support to detect .yml files as yaml protocol.

Blueprint

  • Added conduit::blueprint::mesh::examples:generate driver functions that supports creating any blueprint example mesh with options.
  • Added conduit::blueprint::mesh::examples:generate_default_options functions that provide default options values for conduit::blueprint::mesh::examples:generate.
  • Added python API support for conduit::blueprint::mesh::examples:generate and conduit::blueprint::mesh::examples:generate_default_options.
  • Added gyre example mesh, which provides a simple velocity vector field.
  • Added bent_multi_grid example mesh, which provides a multi-grid that can contain enhanced and reduced connectivity. bent_multi_grid can produce meshes like the example at http://visitusers.org/index.php?title=Representing_ghost_data#Enhanced_and_Reduced_Connectivity_Zones .
  • Added new utilities for material sets: conduit::blueprint::mesh::matset::count_zones_from_matset(), conduit::blueprint::mesh::matset::is_material_in_zone(), and conduit::blueprint::mesh::matset::create_reverse_material_map().
  • Added a new example, conduit::blueprint::mesh::examples::venn_specsets(), which covers the breadth of species set representations.

Relay

  • Added limited support for species sets for Silo/Overlink I/O. Multi-buffer element-dominant species sets can be written to Silo and the same can be read from Silo. Additional species set flavors will come online in a later release.
  • Added support for conduit_yaml and conduit_base64_yaml I/O cases.
  • Standardized the way that Relay Silo Save handles name collisions and non-idiomatic Silo names.

Changed

Conduit

  • Changed the MPI CMake target used by conduit from MPI:MPI_CXX to MPI:MPI_C to provide better compatibility with downstream tools.
  • Added vendored yyjson v0.10.0 as new and default JSON parser. yyjson has an MIT license that is compatible with Debian's Free Software Guidelines, where RapidJSON is not (https://wiki.debian.org/qa.debian.org/jsonevil). You can still use RapidJSON by setting the new CMake option ENABLE_YYJSON to FALSE.
  • The DataType::equals() method now correctly takes striding into account.

Blueprint

  • Certain algorithms that use MPI tags had their tag values lowered since some MPI implementations do not support large values.
  • Changed the name of conduit::blueprint::mesh::matset::to_sparse_by_element() to conduit::blueprint::mesh::matset::to_uni_buffer_by_element() to be more consistent with similar function names.
  • Expanded the ways species sets can be represented in Blueprint to include sparse by element and sparse by material representations, much like material sets.
  • Updated conduit.relay.io.blueprint.{load_mesh|read_mesh} to support reading and writing Silo files when Conduit is built with Silo support.
  • Updated conduit.relay.io.blueprint.{load_mesh|read_mesh} to use improved logic to auto detect the format (hdf5 , silo, yaml, or json) of mesh blueprint root files. Added silo logic, and fixed prior logic that could confuse yaml as json files due to format specifiers in partition pattern strings.

Relay

  • User-supplied warning and error handlers are suspended during conduit::relay::communicate_using_schema::execute() so exceptions will be thrown properly when there is an MPI error. The handlers are restored before the execute method returns.
  • conduit::relay::communicate_using_schema::execute() flushes logs as they are generated, in case of error. This is mostly to facilitate internal debugging.
  • Changes were made to how Relay queries the upper limit for MPI tags to work around problems on some systems.
  • Rewrote conduit::blueprint::mesh::specset::to_silo() to allow it to support specsets that do not use all the materials in the associated matset.
