Feb 1, 2026February 2026 — TTNN JIT Test Suite Optimization (tenstorrent/tt-mlir). Delivered a targeted reduction of the TTNN JIT test suite to accelerate nightly CI while preserving essential coverage. Key changes include reducing test/ttnn-jit/nightly tests from 6,132 to 3,094 (~50%), keeping all 64 grids for rank-2 L1 tests, and trimming rank-3/4 grids to 7 representative configurations. Also narrowed test_matmul.py, test_layouts.py, and test_eltwise.py coverage; removed f32 from TTNN interop tests; and achieved a ~6% reduction in non-nightly JIT tests. This work is linked to commit 059e395618b53c8454a0fa4880d1ae78dfb86d5f and ticket #7180. Impact: faster nightly test cycles, quicker feedback for uplift workflows, and preserved coverage for critical TTNN components. Technologies/skills demonstrated: test-suite optimization, coverage strategy, grid-based test selection, CI efficiency improvements, and Python/test infra adjustments.
