0.9.4 Release Highlights

(adapted from Conduit's Changelog )

Released 2025-04-03

Added

Conduit

• Added conduit::utils::memory_usage helper.
• Added an example demonstrating a strategy to use Umpire with Conduit's allocators.
• Added conduit::utils::memory_usage helper.
• Added extra unit tests for native signed and unsigned Node set methods.
• Added support to read a HOST_CONFIG environment variable to allow pip installs. When set, pip install will pass a host config file to set CMake options.

Blueprint

• Added conduit::blueprint::<mpi>::mesh::state(), conduit::blueprint::<mpi>::mesh::cycle(), and conduit::blueprint::<mpi>::mesh::time(), utilities for getting state information from meshes.
• Added conduit.blueprint.mpi, conduit.blueprint.mpi.mesh, and conduit.blueprint.mpi.mesh.examples modules to the Python interface.

Relay

• Added h5z-zfp compression support to relay io hdf5 methods.
• Added conduit::relay::<mpi>::io::blueprint::generate_root_filename(), which takes the same arguments as save_mesh or write_mesh and produces the name of the root file that would be generated by a call to save_mesh or write_mesh.
• Added conduit::relay::mpi::memory_usage and conduit::relay::mpi::memory_stats helpers.
• Added conduit.relay.mpi.io and conduit.relay.mpi.io.blueprint modules to the Python interface.
• Added v1120 and v1140 options to hdf5 libver settings to support 1.12 and 1.14 libver upper range.

Changed

Conduit

• Updated build system to use blt 0.7.0.
• Changed Conduit memory handler callbacks from function pointers to std::function objects, allowing users more flexibility in dealing with different memory spaces.
• Adjusted how imported CMake target conduit::conduit_python locates python headers for case where Conduit's python module is installed as part of the overall conduit install.

Relay

• Ported relay and blueprint zfp support to use zfp 1.0 api. Added extra meta data to zfparray blueprint protocol to support roundtrip wrapping and unwrapping with zfp 1.0 api.
• Added conduit::relay::mpi::memory_usage and conduit::relay::mpi::memory_stats helpers.

Fixed

Relay

• Fixed an issue with the relay hdf5 detection heuristic on windows.
• Fixed a bug with path creation logic that impact reading mesh blueprint data on windows.
