Usable VRAM is \(\max(0, a - s)\) for available bytes \(a\) and reserve \(s\). +- **Peak** is \(b \cdot c + w\) for batch \(b\), per-observation charge \(c\), and working set \(w\). Overflow fails closed. +- **OOM retry** is stateful: retry count \(r\) increments after each observed OOM, batch is halved when \(r\leq r_{max}\), and the peak is recomputed from the original workload. No loop is counted as a retry unless an executable plan is returned to the caller. +- **CPU `f64` reference** uses deterministic compensated summation in IEEE 754 binary64 so cancellation-heavy low-order terms are not needlessly discarded (IEEE, 2019; Ogita et al., 2005). +- Streamed document/topic cardinalities are not multiplied into a hypothetical full-corpus allocation; the forbidden full-corpus policy is rejected by the controller. +- Mixed precision may be recorded as a transient mode only; final diagnostics remain binary64 (Micikevicius et al., 2018). + +## Verification + +- cancellation-heavy CPU `f64` weighted sums recover the low-order term and known totals with computed RMSE; +- 24-GiB profiles admit a larger autotuned micro-batch than 4-GiB profiles for the same workload; +- each accepted OOM retry returns a smaller GPU plan and an exact retry count before CPU fallback; +- streamed extreme cardinalities remain valid because no full tensor is sized; +- negative parity tolerances, full-corpus placement, observation drop, complexity reduction, cutoff mutation, mixed-final precision, and source-text telemetry fail closed. +''' +Path("docs/research/vram-budget-types.md").write_text(RESEARCH, encoding="utf-8") + +changelog_path = Path("CHANGELOG.md") +changelog = changelog_path.read_text(encoding="utf-8") +bullet = "- `compute_backend` ADR 0006 first slice: VRAM profiles and reserve-aware micro-batching, executable successive OOM retry plans, CPU fallback, compensated `f64` reference arithmetic, non-negative parity tolerance, and fail-closed estimand-preserving memory policies.\n" +if bullet not in changelog: + marker = "### Added\n\n" + if changelog.count(marker) != 1: + raise SystemExit("CHANGELOG Added marker mismatch") + changelog = changelog.replace(marker, marker + bullet, 1) +changelog_path.write_text(changelog, encoding="utf-8") From 2a0240816bd5472b5bbacf85ce60e0f2c66b00ba Mon Sep 17 00:00:00 2001 From: Seongho Bae Date: Fri, 14 Aug 2026 22:28:52 +0900 Subject: [PATCH 010/117] ci(compute): verify executable OOM recovery plans --- .../repair-pr51-executable-oom-retries.yml | 95 +++++++++++++++++++ 1 file changed, 95 insertions(+) create mode 100644 .github/workflows/repair-pr51-executable-oom-retries.yml diff --git a/.github/workflows/repair-pr51-executable-oom-retries.yml b/.github/workflows/repair-pr51-executable-oom-retries.yml new file mode 100644 index 000000000..17bf39f8e --- /dev/null +++ b/.github/workflows/repair-pr51-executable-oom-retries.yml @@ -0,0 +1,95 @@ +name: Repair PR 51 executable OOM retries + +on: + pull_request: + types: + - synchronize + - reopened + - ready_for_review + +permissions: + contents: read + +concurrency: + group: repair-tepp-pr-51-executable-oom-retries + cancel-in-progress: true + +jobs: + repair: + if: >- + github.event.pull_request.number == 51 && + github.event.pull_request.head.repo.full_name == github.repository && + github.event.pull_request.head.ref == 'agent/compute-backend-vram-budget' + runs-on: ubuntu-latest + timeout-minutes: 45 + permissions: + contents: write + steps: + - name: Checkout exact PR branch + uses: actions/checkout@631c942040754b6e095e929c1677c07e10ed4f87 + with: + ref: agent/compute-backend-vram-budget + fetch-depth: 0 + persist-credentials: true + + - name: Merge current protected main + run: | + git fetch origin main + git merge --no-edit -X theirs origin/main + + - name: Install pinned Rust toolchains + run: | + rustup toolchain install 1.97.1 --profile minimal --component clippy --component rustfmt --component llvm-tools-preview + rustup toolchain install nightly-2026-08-01 --profile minimal --component llvm-tools-preview + + - name: Add recovery and numerical regressions + run: python3 scripts/repair_pr51_add_recovery_tests.py + + - name: Prove old recovery contract is RED + run: | + set +e + output=$(cargo +1.97.1 test -p compute_backend --test vram_budget_contract 2>&1) + status=$?

Usable VRAM is \(\max(0, a - s)\) for available bytes \(a\) and reserve \(s\). -- **Peak** is \(b \cdot c + w\) for batch \(b\), per-observation charge \(c\), and working set \(w\). Overflow fails closed. -- **OOM retry** is stateful: retry count \(r\) increments after each observed OOM, batch is halved when \(r\leq r_{max}\), and the peak is recomputed from the original workload. No loop is counted as a retry unless an executable plan is returned to the caller. -- **CPU `f64` reference** uses deterministic compensated summation in IEEE 754 binary64 so cancellation-heavy low-order terms are not needlessly discarded (IEEE, 2019; Ogita et al., 2005). -- Streamed document/topic cardinalities are not multiplied into a hypothetical full-corpus allocation; the forbidden full-corpus policy is rejected by the controller. -- Mixed precision may be recorded as a transient mode only;

Each +crate exposes a bounded, tested contract for evidence, temporal semantics, +event and relation reasoning, membership, persistence, simulation, validation, +API exchange, compute planning, or evidence-grounded interpretation. Numerical +and psychometric authority remains on the CPU `f64` reference path; streamed +accelerator plans must preserve the full observation set and fail closed to the +reference path when resources or validation are insufficient. + +These are production contracts, not a claim that the complete commercial +estimator, operator workspace, or supported release already exists.
