The released SBSA manylinux wheel is not optimized today. L0_Test.groovy's runLLMBuild() compiles it separately from the packed tarball and uploads it straight to <arch>/, and ENABLE_BOLT_COMPATIBLE=ON only makes those binaries BOLT-able -- it does not apply the optimization. The tarball gets BOLTed elsewhere (Build.groovy pre-merge, BoltProfileGen post-merge), so the wheel was the one release artifact with no path to it at all. apply_bolt.py already knew how to BOLT a wheel and regenerate its RECORD; that code was only reachable for wheels packed inside a release tarball. Add a --wheel mode that reuses process_wheel() on a standalone .whl, and teach apply_latest.sh to pick tarball-vs-wheel mode from the input extension (--manifest stays tarball-only: it verifies ELF hashes against the release layout, which a bare wheel has no tree for). runLLMBuild() then applies the branch's latest promoted bundle in place, before the upload and before the local pip install and the DLFW repack, so every consumer sees the same bytes. Scoped to aarch64 with an empty wheel_path, i.e. the wheel published at the root of <arch>/ that the release job picks up; an imageTest/ build is a throwaway wheel compiled inside an already-released image to prove that image can still build from source, so optimizing it would prove nothing and only add a failure mode. Failure handling mirrors Build.groovy's applyLatestBolt: a real apply error is always fatal (never upload a half-BOLTed wheel), while a MISSING bundle is the cold-start case and is fatal only for a nightly_release run, whose wheels the release job actually publishes. Otherwise it is a loud skip, so cutting a new branch does not start failing every sanity-check build. Verified locally against a synthetic wheel with a stubbed llvm-bolt: the profiled lib changes, the unprofiled one does not, every RECORD row still matches the archive contents, the input wheel is left untouched, and apply_latest.sh returns 0 / 3 / 2 on apply, missing bundle, and apply error.

…wheel boltOverlayEnabled and boltProfilesRequired only govern the profile BUNDLE baked in as a thin Dockerfile.bolt layer, which documents how to reproduce a BOLTed build but leaves the binaries the image actually installs unoptimized. Nothing governs the installed wheel, and the tarball it comes from is whichever one exists first -- the canonical, unoptimized one, since Build-Docker-Images runs in parallel with the SBSA branch. Add boltRequireBoltedWheel: when set, the SBSA release image is built from bolted-<tarball> (get_wheel_from_package.py --bolted) rather than the canonical tarball, waiting for it to be published and failing if it never is. Kept independent of the overlay flags so it can be rolled back on its own, and scoped to sbsa because x86_64 has no promoted bundle to wait for. Two supporting changes. The wait gets its own, much longer clock: the canonical tarball lands when the build stage finishes, the BOLTed one only after BoltProfileGen's SLURM fan-out, whose own stage timeout is 8h -- so 60 minutes is the wrong budget for it. And the retry that rebuilds the wheel from source when a build fails with the download args is disabled for this path: it is a fine recovery for an ordinary build, but here it would silently produce an unoptimized release image that looks identical to an optimized one. Also pins wget's output name in the download loop. Without -O it falls back to <name>.1 when a previous attempt left a partial file behind, and the extract would then read stale bytes -- a latent bug that gets much more reachable now that the loop can run for hours. Default false, so this is inert until a follow-up change turns it on. Signed-off-by: Matt Lefebvre <[email protected]>
…mage Pass boltRequireBoltedWheel=true from both BuildDockerImages launches, so the SBSA release image is built from bolted-<tarball> instead of racing the canonical tarball and permanently baking in the unoptimized wheel. Both launches are set together because they push the same tags: the scanned and registered artifact has to be the same image the post-merge path publishes. The scaffolding landed inert in the previous change, so this only answers "should this pipeline require the optimized build". Operational note: this makes the SBSA release image build wait on BoltProfileGen rather than on Build-SBSA -- up to 8h rather than 60 minutes -- because that is what depending on the optimized artifact costs. The alternative is to decouple and have the image apply the branch's previously promoted bundle itself, the way pre-merge consume and the image overlay already do, which gets optimized images with no wait and no race at the cost of profiles from the prior commit. Rollback: drop boltRequireBoltedWheel from both launches, or set the job parameter to false. Nothing else has to change -- the canonical tarball is untouched by BOLT, so the image falls straight back to it. Signed-off-by: Matt Lefebvre <[email protected]>

Review feedback: the "keep in sync with scripts/bolt internal/slurm_*.sh" comment was a one-way reference with nothing on the other end. The pin had five copies -- slurm_merge.sh, perf_instrument_hook.sh, Build.groovy, BoltProfileGen.groovy, and the one this PR added in L0_Test.groovy. Drift between them is not a build error: instrumentation, merge and apply exchange .fdata/.yaml profiles whose formats are not guaranteed stable across releases, so a mismatched version silently produces a bad or empty profile. A comment asking five call sites to stay in sync is the wrong tool for that. Move the pin to scripts/bolt/internal/llvm_bolt_version.sh and source it everywhere. The Groovy callers read it from the checkout they already have rather than interpolating a literal, so bumping the version is now one line in one file. The conditional assignment is preserved, so LLVM_BOLT_VERSION from the environment still overrides it for a one-off run. Two resolution details. BoltProfileGen builds the tarball name and cache key shell-side now, because its staging step runs after the cluster-side extract and so can source the file from the extracted tree. slurm_merge.sh resolves via TOOLKIT_HOST rather than BASH_SOURCE, because sbatch runs a copy of the script out of the node's spool directory and its own path says nothing about where the toolkit lives -- the same reason that file already took TOOLKIT_HOST from the environment. Signed-off-by: Matt Lefebvre <[email protected]>
… run mode Review feedback, two parts. nightly_release was the wrong trigger. The wheel the release job publishes is the same artifact whether the run is nightly, weekly or GA, so keying off one run mode meant the others shipped un-BOLTed. The question is "is BOLT on", not "is this a nightly". And the step ignored the pipeline's BOLT switch entirely -- it would have run on any nightly_release regardless of whether the run asked for BOLTed binaries. Gate on globalVars.bolt_consume_build, the same value L0_MergeRequest::resolveBoltConsume hands the build helpers for the tarball, so the released wheel and the released tarball can never be optimized differently. Read with the ?.toString() == "true" idiom Build.groovy already uses, since the value crosses a JSON parameter boundary. With the switch as the trigger, the required/optional split goes away: a missing bundle is now fatal like every other failure. "BOLT is on" has to mean the wheel IS optimized -- degrading to an un-BOLTed wheel with a log line is exactly how an unoptimized artifact reaches PyPI unnoticed. This is stricter than Build.groovy's applyLatestBolt, which skips on a missing bundle; it has to be lenient because the same switch covers x86_64, where nothing is promoted yet, while this path is aarch64-only and the switch is main-only. Known gap worth a look: resolveBoltConsume also disables the switch for post-merge, because the post-merge TARBALL is the un-BOLTed input BoltProfileGen profiles. That reasoning does not apply to this wheel -- it is a separate build that BoltProfileGen never reads -- so post-merge sanity-check wheels stay un-BOLTed as a side effect. Harmless today (those wheels are not released), but say the word if the release path ever draws from a post-merge run and it should get its own switch instead.

Review feedback, two related holes in the apply path. bolt_elf() returned False when llvm-bolt failed and both callers just skipped the member. With two matching ELFs where one fails, the count stayed positive, the wheel was repacked, and the result was uploaded -- a partially optimized artifact is indistinguishable from a fully optimized one, so nothing downstream would ever notice. bolt_elf() now raises BoltApplyError instead. There is no caller that can sensibly continue, so reporting-and-skipping was the wrong shape. main() turns it into exit 2 after the detailed llvm-bolt output bolt_elf already logged, and bolt_standalone_wheel() deletes the copy it made before re-raising, so no half-written wheel is left where a caller might upload it. The loose-ELF loop in the tarball path had the identical hole and is fixed by the same change. Also reject --output == --wheel. process_wheel() rewrites its argument, so the in-place case silently violated the contract the function documents: the input is copied first precisely so a failed apply leaves it usable. Extracting the body into _apply() is what lets main() own the try/except/finally without re-indenting the whole function under a second try. Verified with a stubbed llvm-bolt that fails for one selected library: - wheel, all libs bolt: repacked, RECORD rows all match, unprofiled lib untouched - wheel, one lib fails: exit 2, no output file left behind - tarball, loose ELF fails: exit 2, no output file left behind - --output == --wheel: rejected, input wheel unmodified Signed-off-by: Matt Lefebvre <[email protected]>
Review feedback. prepareWheelFromBuildStage built --artifact_path from env.uploadPath directly. The two agree whenever the parent passed the parameter, but an unset env interpolates to the string "null" and the download then polls .../null/<tarball>. Pre-existing, and previously self-limiting: the poll timed out and the build fell back to compiling the wheel from source. This change removes that fallback for the BOLT-required SBSA path and stretches the wait to 8h, so the same typo now costs most of a day and then fails. UPLOAD_PATH already carries the job-scoped default for exactly this case. Signed-off-by: Matt Lefebvre <[email protected]>

Signed-off-by: Matt Lefebvre <[email protected]>
…for one Reworks this PR from "wait for this run's bolted- tarball" to "BOLT the wheel the image installs, using the branch's last promoted bundle". The previous shape had the release image build block on BoltProfileGen: up to 8h holding a docker builder pod, and only workable post-merge, because nothing publishes a bolted- tarball in a nightly or GA run (the producer is gated on JOB_NAME matching PostMerge). It also quietly contradicted the decision to treat a producer failure as UNSTABLE -- with the image hard-requiring the artifact, a SLURM hiccup failed post-merge anyway, eight hours later, in a stage that looks unrelated to the cause. The image installs a wheel, so optimizing that wheel is the whole requirement; where the profiles come from is a separate question. Taking the last promoted bundle answers it without an in-run dependency: no wait, no race with Build-Docker-Images, and nightly and GA containers get optimized binaries for the first time. The cost is profile drift -- the bundle is from the last successful promote rather than this commit. That is the same contract Build.groovy's pre-merge consume and the Dockerfile.bolt overlay already ship with, and -infer-stale- profile means drift costs optimization quality, never correctness. Same-commit profiles are still used where they are free: the post-merge SBSA test stages run after BoltProfileGen in the same branch and keep preferring this run's tarball. Mechanically this reuses the wheel support added for the release wheel: get_wheel_from_package.py downloads the canonical tarball as before, then runs apply_latest.sh on the extracted wheel before the release stage pip installs it. Dockerfile.multi's wheel stage already COPYs scripts/, so the toolkit is in context. Branch resolution mirrors the image overlay (explicit override, then LLM_BRANCH, then main) and is fatal if none has a bundle. llvm-bolt staging moves into apply_latest.sh via a new stage_llvm_bolt.sh, since the image build cannot stage it the way the Jenkins pods do. It is a no-op when llvm-bolt is already on PATH, and honors GITHUB_MIRROR like install_ccache.sh and install_cmake.sh, which already pull release tarballs from github.com during the image build. boltRequireBoltedWheel is renamed boltOptimizeWheel to match what it now does, and the 8h wait constant is gone. Verified with a stubbed bundle pull and llvm-bolt: a branch with no bundle falls through to the next candidate, the wheel landing in build/ is optimized, its RECORD rows all match, and unprofiled libraries are untouched.

…-bolted-wheel Signed-off-by: Matt Lefebvre <[email protected]>
…mage wheel Follows the rework in the previous change: the parameter is boltOptimizeWheel and it BOLTs the wheel during the image build rather than waiting for this run's bolted- tarball. Two consequences worth noting for review. This no longer depends on the post-merge publication toggle (NVIDIA#19209) at all -- it reads the branch's last promoted bundle, so the only prerequisite is that a bundle has been promoted at some point. And the image build no longer waits on BoltProfileGen, so a producer failure stays UNSTABLE as intended instead of failing post-merge eight hours later from an unrelated-looking stage. Both launches are set together because they push the same tags: the scanned and registered artifact has to be the same image the post-merge path publishes. Rollback: drop boltOptimizeWheel from both launches, or set the job parameter to false. The image then installs the wheel as built, exactly as today. Signed-off-by: Matt Lefebvre <[email protected]>

Description
#19432 added
boltOptimizeWheeland set it on bothBuildDockerImageslaunches, but itcannot take effect, because optimizing the installed wheel is only possible on the
build-stage-wheel path and that path is unreachable. Two gates kill it, and neither has
anything to do with BOLT:
useWheelFromBuildStageis a kill switch added for nvbug 5433581 in Aug 2025 and neverreverted. It was also read without ever being declared as a parameter of this job, so
params.useWheelFromBuildStagewas always null: not merely false, but incapable of beingtrue.
triggerTypeis read from env and is likewise not a declared parameter, so whether itsurvives the launch is a property of Jenkins job registration rather than of this repo.
When it does not,
TRIGGER_TYPEis"manual"and the function returns early no matterwhat the caller asked for.
This declares
useWheelFromBuildStageso the flag is at least capable of being set, and letsa BOLT request carry itself past both gates. The bypass is keyed on
boltOptimizeWheel,which is declared and therefore reliably arrives, and is narrowed to one arch and one
dockerfile stage:
So the nvbug's blast radius stays at the SBSA release image instead of being reopened for
every image this job builds.
useWheelFromBuildStageitself stays false by default andnothing turns it on. When the bypass fires it says so in the log, since this is the one place
the image build departs from what its parameters literally asked for.
This is the PR that makes the optimized release image wheel live. Everything before it is
inert.
Rollback
Set
boltOptimizeWheelto false at the twoBuildDockerImageslaunches inL0_MergeRequest.groovy, or set the job parameter to false. Nothing else has to change: thecanonical tarball is untouched, so the image falls straight back to compiling its own wheel.
Before merging
Confirm nvbug 5433581 is resolved. The bypass is deliberately narrow, but it does route
around that bug's kill switch for the SBSA release image.
Test Coverage
No automated tests, this is CI infrastructure.
On a post-merge or nightly-release run, the
make ngc-release_push (sbsa)stage should log[BOLT] boltOptimizeWheel is set for the sbsa release image, so the build-stage wheel path runs even though useWheelFromBuildStage=false, thenApplying BOLT profiles from main/aarch64-linux-gnu to tensorrt_llm-*.whl, thenBOLT optimized tensorrt_llm-*.whl (main/aarch64-linux-gnu). x86_64 is unaffected and stillcompiles its wheel in-container.
The failure mode to watch on the first run is a missing bundle:
get_wheel_from_package.pyraises rather than installing an unoptimized wheel, and the from-source retry is disabled for
this path, so the image build fails loudly instead of silently shipping an unoptimized
release image. That is intended, and it is the reason for the rollback note above.
