- Around line 142-144: Update

the initial NCCL proof as a Certification flow rather than WorkloadRun. Update
lines 146-150 to cover creating the Certification, waiting for completion, and
handling its BandwidthMeasurement results; both sites require documentation
changes.

unique DNS-valid WorkloadRun name for each validation, rather than reusing the
fixed constant. Reuse that generated name consistently for every WorkloadRun
creation, lookup, wait, and deletion operation within the validation.
- Around line 181-201: The WorkloadRun specification in the relevant validator
contains repeated key literals that trigger goconst. Reuse the existing keyName
constant and introduce or reuse constants for mountPath and value, then replace
every repeated "name", "mountPath", and "value" key in this specification while
preserving the generated structure.

capture the non-terminal object’s resource version from the initial Get and
include it in the metav1.ListOptions passed to res.Watch. Ensure the watch
begins at that observed version so terminal updates between Get and Watch are
not missed, and add a test covering this transition.
- Line 71: Update the cleanup-to-creation flow around deleteCREResource and
checkCRENCCLAllReduceBW to wait with a bounded context until the fixed-name
Certification is confirmed NotFound before calling createUnstructured. Add a
test covering a retained finalizer and repeated NCCL checks.

Use catalog Certifications for NCCL and Nemotron-5 8B, always delete the CR, and cap each run to two named nodes with a matching job timeout so AICR wait cannot leave CRE work running. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
AICR's Certification teardown could report a clean cleanup while CRE's jobs were still holding GPUs, and could report a passing check on top of a Certification it failed to delete. Delete with foreground propagation so the parent CR is retained until CRE's Workflows, TrainJobs, and pods are gone, making the existing gone-wait actual evidence the GPU work stopped. Give teardown its own budget instead of borrowing the shorter DiagnosticTimeout, which would expire mid-termination and leak a running job. Route both checks through creCleanupFailure so a failed or timed-out teardown fails the check, while preserving an error the check already hit. These bounds are enforced by AICR at the call site: CRE's API places no upper bound on nodesPerJob and has no whole-Certification deadline. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
Deleting the Certification does not establish that its GPU work stopped. CRE's Certification controller deletes its child Workflows and drops its own finalizer in the same reconcile without waiting for them, and its Job drain barrier gives up after five minutes and proceeds while pods are still running. Foreground propagation is therefore necessary but not sufficient, so observing the parent disappear proved nothing. Teardown now walks Certification -> Workflows -> Jobs by label before the delete, because CRE stamps the Certification name only on its Workflows, then waits for every TrainJob and non-terminal workload pod carrying those Job names to disappear. An unconfirmed teardown fails the check rather than warning: surviving work still holds the GPUs. The teardown budget is separated from the delete budget and sized to outlast CRE's five-minute drain grace plus pod termination. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>

…on record Both CRE checks gated on 'service != eks || accelerator != h100' in Go, and the catalog variant and node cap were package constants. That made every further combination a code change and buried compatibility in branching. Record the qualified combinations as data instead. creQualifiedEntries maps a check and a criteria pair to the catalog entry and node footprint it was measured with, and the checks look it up rather than branching. Qualifying a combination is now an entry plus a measured threshold in the recipe. capCRECertificationNodes takes the cap from that entry and clamps a missing one to a single node, so a malformed entry fails an all-reduce loudly rather than quietly consuming the GPU pool. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
The checks no longer branch on criteria, so the docs, catalog descriptions, and check-name comments should not read as though EKS H100 were their scope. Point each at the qualification record and name eks x h100 as the combination qualified today. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>
…ribution Both checks now skip an unqualified combination instead of branching on criteria, so test that path directly rather than inferring it from the record. listMaxBusBandwidth and getGoodputStatus were uncovered, and they carry the run-attribution rules the checks depend on: a certification can rerun on nodes still holding an earlier run's measurements, so both filter by owning Workflow and by creation time. Cover the peak-selection, wrong-workflow, stale-object, and no-results cases against a fake dynamic client. Also replaces a test case duplicated verbatim in the goodput condition-summary table with the no-True-condition case it was missing. Signed-off-by: Rohit Rajani <rorajani@nvidia.com>

Summary
Adds the two opt-in Cluster Readiness Engine performance checks against public CRE (
nvcre.nvidia.com), each driving its ownCertification: NCCL bus bandwidth and training goodput. Neither check branches on service or accelerator — which combinations are qualified is recorded as data, andeksxh100is the first entry. Shipped overlays keep TrainJobnccl-all-reduce-bw; CRE stays catalog-only until a later overlay flip.Motivation / Context
CRE is public at https://github.com/NVIDIA/cluster-readiness-engine, so the NCCL check no longer depends on private Excalibur. The Helm install of CRE is #2524, so this change cannot attach
nvcreto any overlay.This is the validator half of ADR-025's Phase 1. It carries most of the bounded
Certificationdriver (#2688) and both opt-in checks (#2689), including the provider-independence and derived-catalog-entry-selection points raised in review on the epic (#2683).It does not close either issue, so neither is listed as
Fixes. Still outstanding against #2689: the four remaining goodput metrics (avgTFLOPSPerGPU,avgStepTimeSec,interruptionCount,lostWorkTimeSec) are printed but are not constraints; evidence does not yet name failing nodes with a per-node reason; and thegangSchedulerposition is undecided. Against #2688: a missingtarget.nodeNamesis guarded by the callers' two-node check rather than failing before the resource is created, an expired run does not carry the partial report, and a run whose resources were superseded by a platform override is not yet reported explicitly.Fixes: N/A

Certificationis the surface for both checks. The API group isnvcre.nvidia.com(public CRE), notexcalibur.nvidia.com.nccl-cre-all-reduce-bwreads the peakbusBWfrom the category Workflow'sBandwidthMeasurementand then asserts NET/EFA from launcher logs, so a run that silently fell back to another transport fails rather than reporting a number.cre-training-goodputreads theGoodputMeasurement. Each check creates its ownCertificationso their deadlines, teardown, and verdicts stay independent.Qualified combinations are data, not branches. Both checks previously gated on
service != eks || accelerator != h100in Go, and the catalog variant and node cap were package constants.creQualifiedEntriesinvalidators/performance/cre_qualification.gonow maps a check plus a criteria pair to the catalog entry and node footprint it was measured with, and the checks look that up. Qualifying a combination is an entry there plus a measured threshold in the recipe, never a new code path. The entry has to be per combination:training/nemotron5-56bneedsminGPUs: 32and fails on 2x p5, wherenemotron5-8bpasses.An unqualified combination skips. It has no calibrated threshold to judge against, so running the benchmark and comparing it to another platform's number would be worse than not running it.
Execution stays bounded. The node cap reaches both
spec.nodesPerJobandspec.target.nodeNames, because setting only the former still fans out one job group per pair across the whole GPU pool.capCRECertificationNodesclamps a missing cap to a single node rather than treating it as unlimited — a one-node all-reduce fails loudly, where an uncapped run quietly consumes the pool.spec.timeoutPerJobcarries AICR's own wait budget so CRE stops the job instead of leaving it running after AICR gives up. Teardown deletes with foreground propagation and then confirms theTrainJobs and workload pods are gone, since CRE's controller drops its finalizer without waiting for them; an unconfirmed teardown fails the check rather than warning, because surviving work still holds the GPUs.Opt-in is locked by test.

Certificationmove for goodput, so it needs re-running before merge to confirm both checks still measure the same numbers through the new path.Risk Assessment
Rollout notes: Catalog checks only. A recipe must list the check and a same-named constraint, and the cluster must have public CRE installed (#2524 or a manual chart install). No shipped overlay references either check, so there is nothing to roll back for existing consumers. Do not attach the CRE NCCL check to overlays until the TrainJob correlation gate (#2691) resolves; per the epic, that gate governs the NCCL migration only, not the training or fault-isolation capability.
