Release Notes
Added
- Execution topology reporting — leverage ferrompi v0.3.0 to gather MPI
library version, rank-to-host mapping, thread level, and SLURM job metadata
at initialization. New TopologyProvider trait in cobre-comm with
ExecutionTopology types. Displayed after the banner during cobre run and
persisted in metadata JSON output.
- Solver version reporting — expose HiGHS version via
Highs_versionMajor,
Highs_versionMinor, Highs_versionPatch C API wrappers. Version displayed
in the Execution section, cobre version, and metadata JSON.
- Backward pass work-stealing — replace static partitioning with atomic
counter work-stealing for better load balance across MPI ranks.
- Stage-major simulation loop — refactor simulation pipeline from
scenario-major to stage-major ordering, eliminating redundant LP setup calls.
- Lazy FCF growth —
CutPool grows its coefficient storage on demand
rather than pre-allocating to max capacity.
- Parallel lower bound evaluation — evaluate lower bound across openings
in parallel using the rayon thread pool.
SolverInterface::solver_name_version() — new trait method for solver
identity reporting.
Changed
- Metadata JSON schema (breaking) —
mpi object replaced by distribution
with richer fields: backend, world_size, ranks_participated,
num_nodes, threads_per_rank, mpi_library, mpi_standard,
thread_level, slurm_job_id, and solver_version.
cobre version output — now shows the HiGHS version alongside the
solver name.
Fixed
- Fixed 34 assessment findings across the workspace (error handling, edge cases,
documentation accuracy).
- Fixed rustdoc private-intra-doc-link warning in
visited_states.rs.
- MPICH multi-line
MPI_Get_library_version output is now sanitized to a
single-line identifier for display.
