Updates

• Build related:
  • Clang ASAN + LSAN Checks in CI
  • Resolved a few ASAN issues
  • Use CMake MPI::MPI_C target instead of MPI::MPI_CXX, and OpenMPI related woes
  • build_conduit.sh
• Mixed element support added to Ascent + VisIt -- Q: status on VisIt shape_map PR?
• Added Gyre Mesh BP Example
• Added Mixed Topo Mesh Tests
• Added top level driver to create mesh bp examples (one function that unites all examples):
  • https://github.com/LLNL/conduit/blob/92e22b350fe6320e6f298b9f7429b6bf1085b542/src/tests/blueprint/t_blueprint_mesh_examples_generate.cpp#L57
  • Want similar nice things ... (Top level Mesh BP Transforms Interface)
• Justin working on device support and becoming YAML schema MAN.
• Brad: Axom views of Conduit Topologies, has an Isovolume algo that is running on the GPU.
  • Justin and Cyrus will look at Brad's infrastructure
• Arlie: Enhanced and Reduced Connectivity example.
• Brad: Would be nice to have the ability to provide extra call back data to allocators, add an optional void * param that is kept and passed to callbacks.

Future:

• Conduit Device Execution Strategy (https://github.com/LLNL/conduit/issues/1151)
• Workflows that are using in-transit with near-node storage
• Learn how to talk to S3 object stores as an end point for Conduit Nodes. - Strategy for Object Storage (S3) (libcurl example https://github.com/cedricve/AWS-S3-Cpp-REST-API)
• Explore ZFP (or even ZLIB) Compression in HDF5 for ML Ensemble Data (Floating Point Images / Regular Grids)
• Stricter set semantics? https://github.com/LLNL/conduit/issues/941
• Blueprint Helpers:
  • Top level Mesh BP Transforms Interface: ( https://github.com/LLNL/conduit/issues/93)
  • Modify names of mesh bp entries (rename a topology, rename a field) (https://github.com/LLNL/conduit/issues/940).
• Blueprint to GLTF / ANARI.
• Blueprint to VTK
