Release Notes
Added
- HistoricalResiduals noise method — new
NoiseMethod::HistoricalResiduals
variant that copies pre-computed eta vectors from HistoricalScenarioLibrary
into the backward-pass opening tree, preserving empirical cross-entity
correlation from actual inflow observations. Uses hash-based deterministic
window selection and skips Cholesky decorrelation.
- Season ID consistency validation (rules 27–30) — four new semantic
validation sub-rules: season range coverage, observation coverage per season,
resolution consistency across seasons, and contiguity of defined seasons.
- Observation alignment validation (rule 31) — validates observation-to-season
alignment with a three-tier season mapping fallback chain. Replaces hardcoded
month0() in historical window discovery and standardization with
SeasonMap-aware logic.
- SLURM MPI test infrastructure — replaced
mpi_smoke.sh with
mpi_slurm.sh for Dockerized SLURM cluster testing.
Changed
- Timing instrumentation columns — renamed for accuracy:
forward_solve_ms → forward_wall_ms, backward_solve_ms →
backward_wall_ms, mpi_broadcast_ms → cut_sync_ms,
rayon_overhead_ms → bwd_rayon_overhead_ms. Added lower_bound_ms
and fwd_rayon_overhead_ms. Removed stub columns forward_sample_ms,
backward_cut_ms, io_write_ms.
Fixed
- LP determinism across MPI configurations — reload LP model per
scenario/trial-point to prevent HiGHS internal state carry-over (basis, RNG
position) from making results depend on rank/thread count. Verified
bit-identical lower bounds across 1r/1t, 1r/2t, 2r/1t, and 1r/4t.
- Forward pass sampler count — pass global
total_forward_passes to the
sampler instead of the per-rank local count, fixing LHS/QMC determinism
across MPI configurations.
- Timing overhead double-counting — fix
overhead_ms always being zero
due to cut_sync_ms included in both backward_ms and the attributed sum.
- Historical window year normalization —
build_observation_sequence now
normalizes year offsets so the first study stage gets year_offset=0,
fixing incorrect window matching for studies not starting in January.
- MPI handling — fix MPI communication edge cases.
