Summary

Run the upstream DeepSeek-V4-Pro aggregated deployment and existing upstream synthetic AIPerf Job after the nightly vLLM image is copied to ACR. The GCP Kustomize overlay supplies the shared model cache, scheduling, and nightly runtime image pinned to its ARM64 digest.

Match the GitLab nightly workload sizes and counts: 8,192 input tokens, 1,024 output tokens, concurrency 1 8 64 128 256 512 1024, 16 warmup requests per concurrency, 3 × concurrency measured requests, and seed 100. Reuse recipes/deepseek-v4/deepseek-v4-pro/vllm/disagg/gb200/perf.yaml against the aggregated endpoint; its command and AIPerf 0.12.0 remain unchanged. Allow the benchmark's 12-hour deadline, collect every sweep's artifacts, and require each of the seven results to have the expected request count, zero errors, and positive output.

Reuse the deployment runner's bundled tools for preflight, live logs, artifacts, and cleanup. Keep explicit per-run pull secrets and artifact paths. Six YAML files; no scripts, tests, README, or docs added.

Validation

  • Repeated Kustomize renders were byte-identical. Shell syntax checks and existing repository hooks passed at 753b3434d5.
  • Offline execution of the sweep with AIPerf stubbed confirmed all seven workload configurations and request counts. The exact workflow verification accepted seven valid exports and rejected missing exports, request errors, incorrect counts, and zero output.
  • The updated benchmark Job passed a server-side dry run on gc-dev-02; the rendered aggregated DGD and ComputeDomain are unchanged.
  • The new synthetic sweep has not run on GPUs. The previous live run reached DGD readiness and model discovery before vLLM failed in ncclCommWindowRegister with NCCL error: unhandled cuda error. That runtime failure remains unresolved.
  • The existing recipe validator supports v1beta1 only; the deployment preserves upstream v1alpha1. Kimi-first onboarding (OPS-8639) remains a separate prerequisite.

OPS-8657

Summary by CodeRabbit

  • New Features
    • Added automated nightly performance testing for DeepSeek V4 Pro aggregated deployments, with an option to run the workflow manually.
    • Added a preflight mode to validate deployment and benchmark configurations without running the performance test.
    • Performance runs check request counts, errors, and output lengths, and retain diagnostic and performance results for review.
    • Nightly CI now includes this performance job and waits for it to finish before sending notifications.

Walkthrough

Adds a DeepSeek V4 Pro aggregate performance deployment and benchmark job. A reusable workflow supports preflight validation, execution, result checks, cleanup, and artifact upload. Nightly CI invokes the workflow and waits for it before Slack notification.

Changes

DeepSeek V4 Pro nightly performance

Layer / File(s) Summary
Deployment and benchmark manifests
.github/ci/deepseek-v4-pro-agg/*
Adds the Kustomize configuration and patches for the deployment and benchmark job. The deployment uses the shared model-cache PVC, ARM64 scheduling, and worker pod affinity. The benchmark job specifies its endpoint, target model, and shared cache mount.
Workflow setup and preflight
.github/workflows/deepseek-v4-pro-nightly.yml
Defines workflow inputs and settings, resolves the ARM64 image digest, renders manifests, checks the PVC, and validates resources and credentials.
Deployment and benchmark execution
.github/workflows/deepseek-v4-pro-nightly.yml
When preflight-only mode is disabled, creates the deployment, waits for readiness, starts the benchmark job, and polls for completion.
Result checks, artifacts, and cleanup
.github/workflows/deepseek-v4-pro-nightly.yml
Collects diagnostics and performance files, checks AIPerf results, attempts to delete run-scoped resources and credentials, and uploads artifacts with 14-day retention.
Nightly CI wiring
.github/filters.yaml, .github/workflows/nightly-ci.yml
Extends the shared CI filter to match .github/ci/**. Adds the performance workflow to nightly CI and includes its completion in Slack notification dependencies.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 09d5f

The nightly benchmark can lose its performance artifacts and skip result verification if the frontend Pod is replaced mid-run. Looking up the current frontend Pod before copying fixes this. The risk is confined to CI, so the change is mergeable with that follow-up.

Approving at 09d5ff264e. No P0 or P1 is open, but the new P2 below means that the nightly can stay red after the NCCL fix. Please read it before you merge.

  • [P2] New: the inherited trace does not fit the 7,200 s Job deadline or the 1,048,576-token context. patch-perf.yaml:22. Please size the nightly workload.
  • [P2] I agree with the open thread at deepseek-v4-pro-nightly.yml:157. The names are fixed, but cleanup selects only the label of the current run. Please also delete the fixed names before preflight.
  • [P3] On the CodeRabbit thread at deepseek-v4-pro-nightly.yml:148, a stale name turns the run red, not green. Its committable suggestion fails every preflight-only run, so do not commit it as written.

This nightly workflow cannot run on a PR. The main evidence is dispatch run 36509765198 at 404fe70a6b, the only full run, and it failed on the NCCL error that the description names. The rebase to 09d5ff264e changed only the needs line of notify-slack. The job DeepSeek V4 Pro aggregated perf in Nightly CI Pipeline has not run yet.

What I tested.
  • The triggers are workflow_call from nightly-ci.yml and workflow_dispatch, so a fork PR cannot start the workflow. The token has contents: read, and both external actions are pinned by SHA.
  • The overlay renders offline with kubectl 1.36.3 and kustomize v5.8.1. The patches reach dsv4-pro-agg and dsv4-bench. The result asks for 8 GB200 GPUs on 2 arm64 nodes and mounts the existing shared-model-cache PVC. The worker runs with HF_HUB_OFFLINE=1, so the run downloads no weights.
  • The expression of the Verify step passes the smoke export (3 of 3 requests) and fails the full export (72 of 3,541 requests, 3,469 errors). A failed benchmark fails the job.
  • actionlint 1.7.12 reports nothing new in the changed workflows, except the runner label that existing jobs also use. It caught the wrong input name and the wrong output name that I planted.
  • In nightly-ci.yml, the new job needs the vLLM build and the ACR copy. Only notify-slack waits for it, so a failure alerts Slack and blocks no other job.
  • I did not look at the model cache or the trace files on the cluster.

Previously reported defects still present:

  • Original discussion: Still present: the overlay does not override TRACE_FILE, so the benchmark inherits /model-cache/traces/64k_400_90kv_agent_new_noschedule_short_15perc.jsonl from recipes/deepseek-v4/perf/perf.yaml while the workflow still enforces a 7200-second job deadline and zero AIPerf errors.
  • Original discussion: The current overlay still inherits the 15% trace through the upstream perf Job without overriding TRACE_FILE. The open discussion's verified context-overflow records and minimum decode time therefore still cause the 7,200-second Job or zero-error result check to fail.
  • Original discussion: Verified still present: the overlay leaves the upstream 15% trace and 7,200-second Job deadline unchanged. The previously reported over-context requests and required decode time can still cause benchmark errors or timeout, which makes the zero-error verification fail.
  • Original discussion: Verified still present: the overlay leaves the upstream 15% trace selected, while the inherited Job has a 7,200-second deadline and verification rejects any error. The previously reported oversized/context-overflow workload has not been changed.

Approving again at d494a24290. The new commit fixes the leftover problem on the thread by lavanyavijayk, and no P0 or P1 is open.

  • [P2] Still open, and this commit does not change it: the inherited trace does not fit the 7,200 s Job deadline. patch-perf.yaml:22, on my earlier thread.
  • [P2] Fixed, on the thread by lavanyavijayk: a leftover from a lost runner no longer blocks the next full run. The fix follows my ask there, and my evidence is in my reply.
  • [P3] Fixed, on the CodeRabbit thread: the Collect step now finds the current frontend Pod inside the $FRONTEND guard, as I advised there.
  • [P3] New: a lost run still leaves its two credential secrets in the namespace. deepseek-v4-pro-nightly.yml:95.

This nightly workflow cannot run on a PR, and no dispatch run exists at d494a24290. I ran the two changed steps offline against a kubectl stub. The dispatch runs that I used are 36509765198 and 36483614436, both before this commit. No run of the job DeepSeek V4 Pro aggregated perf in Nightly CI Pipeline exists yet.

What I measured for the Collect step and the workflow syntax.
Collect case 09d5ff264e d494a24290
The first frontend Pod was replaced fails on kubectl cp copies from the running replacement
No running frontend Pod, or only a Pending one fails on kubectl cp copies nothing and passes, then Verify fails on the missing export
kubectl get pods fails makes no lookup fails
Preflight-only run, with FRONTEND empty makes no lookup makes no lookup
  • actionlint 1.7.12 reports nothing new between 09d5ff264e and d494a24290. It caught both defects that I planted in the changed steps: a wrong input name and an unknown step ID.
  • bash -n passes on every step script at both heads.

I approve again at a06a5e7c4a. This commit changes only the image of the benchmark Job, and no P0 or P1 is open.

  • [P2] Open, and this commit does not change it: the inherited trace does not fit the 7,200 s Job deadline. patch-perf.yaml:22, on my thread.
  • [P3] Open, and this commit does not change it: a lost run leaves its two credential secrets in the namespace. deepseek-v4-pro-nightly.yml:95, on my thread.
  • main requires resolved threads, so my two threads hold the auto-merge until you fix or resolve them. The threads by lavanyavijayk at deepseek-v4-pro-nightly.yml:168 and by nv-tusharma at patch-deploy.yaml:53 are also open.
  • Note, not a finding: the Job now uses python:3.12-slim from Docker Hub, as the upstream recipe does. Today, Docker Hub serves the removed pin as the linux/amd64 image of that tag. When Docker Hub moves the tag, the Job can get a different image.

No run of this workflow exists at a06a5e7c4a, and the job DeepSeek V4 Pro aggregated perf in Nightly CI Pipeline has no run yet. A preflight-only dispatch at this commit can show that the cluster accepts the new Job in a server-side dry run.

What I measured for the image change.
  • I rendered the overlay offline with kubectl 1.36.3 (kustomize v5.8.1) and the same edits as the Render step. From d494a24290 to a06a5e7c4a, one line changes. The Job image goes from docker.io/library/python@sha256:44ff437b… to python:3.12-slim. The pull policy stays IfNotPresent, and the Job still has no pull secret and still runs on amd64 nodes.
  • Control: my render of d494a24290 is identical to the rendered.yaml artifact of run 36509765198, after I replace the run key and the vLLM image. A merge with the current main renders the same as a06a5e7c4a.
  • On Docker Hub today, the python:3.12-slim index is sha256:f77ac9e4…. Its linux/amd64 entry is sha256:44ff437b…, version 3.12.14-slim-trixie. A tag that does not exist returns manifest unknown.
  • An early version of this PR, 04a51f3371, recorded the same tag, index, and amd64 digest in benchmark-image.json. Its README says "Preflight verifies platform digests, reproducible rendering". So the pin kept the benchmark image fixed.
  • In runs 36509765198 and 36492265405, the cluster pulled docker.io/library/python@sha256:44ff437b… in 3.332 s and 3.626 s, with no pull secret. python:3.12-slim is a short name for the same Docker Hub repository. In run 36509765198, other pods in the namespace used ghcr.io/ai-dynamo/grove/grove-initc:v0.1.0-alpha.12, a tag with no digest, and busybox:1.37.0@sha256:9db7b599…, a short name.
  • This repository has no registry mirror configuration. I did not measure the node configuration or the Docker Hub pull limit of the cluster. Neither is in the repository or in the CI logs.
  • The fixes in d494a24290 follow my earlier asks, so this approval partly covers my own advice.

I approve again at 4ec2547084. Both fixes hold, and no P0 or P1 is open. One new P2 is open on my new thread. main requires resolved threads, so that thread now holds the auto-merge.

  • [P2] Fixed in 753b3434d5: the inherited trace. My evidence is on my thread.
  • [P3] Fixed in d96ebf6e89: the Secrets of a lost run. My evidence is on my thread.
  • [P2] New: each nightly copies and keeps about 3.2 GB of inputs.json. deepseek-v4-pro-nightly.yml:164.
  • Note, not a finding: notify-slack in nightly-ci.yml waits for this job. With the new 900-minute limit, the Nightly Slack summary can wait up to 15 hours for this job. The old limit was 5 hours.
  • Note, not a finding: the benchmark step has no step limit now. Only a complete or a failed Job ends its loop. If the benchmark Pod never starts, the deployment keeps its 8 GB200 GPUs until the 12-hour Job deadline. The old step limit was 125 minutes.

The rebase to 4ec2547084 changed no line of this PR. No run of this workflow exists at 753b3434d5, d96ebf6e89, or 4ec2547084, and the job DeepSeek V4 Pro aggregated perf in Nightly CI Pipeline has no run yet. So the first full nightly is the first GPU run of the new sweep. The two fixes follow my asks, so this approval partly covers my own advice.

What I tested in this round.
  • I rendered the overlay offline at a06a5e7c4a, 753b3434d5, d96ebf6e89, a merge of d96ebf6e89 with main, and 4ec2547084. The last four render the same.
  • I ran the command of the Job locally with AIPerf 0.12.0 against the AIPerf mock server, and I ran the Verify step on its output. The details are on my threads.
  • For the lost-run test, I ran the Preflight, Deploy, benchmark, Collect, and Clean up steps of each commit offline against a kubectl stub.
  • The 12-hour deadline fits the 900-minute job limit, with 720 minutes for the Job and 170 minutes for the other step limits. The workflow reads the renewed tbot kubeconfig directly. The repository shows no other time limit for this namespace.
  • I did not run anything on a cluster or on a GPU.

Approved at 16a41f7d20, with one open P2. I reopened the inputs.json thread, because the new delete fails for the frontend user, and then the Collect step copies no results.

  • [P2] deepseek-v4-pro-nightly.yml:165: the frontend runs as dynamo (uid 1000) and cannot delete the files that the Job wrote as root. The thread has the measurement and the ask.

This P2 does not block the merge by itself. Auto-merge now waits for the reopened thread. The first nightly will show the P2, or one ls -ln of a run folder on shared-model-cache.

Notes that do not block the merge.
  • No earlier run left inputs.json on the PVC. Run 36509765198 used the trace workload, which does not write the file. The smoke runs of #14893 wrote AIPerf output to /tmp/aiperf in the pod. No run used the synthetic workload yet.
  • If the delete has permission, the fix works. It removes inputs.json from the run folder and from the artifact, and it keeps the results and the folders of other runs.
  • The fix changes only the folder of the current run, so older run folders stay on the PVC. The copied folder of run 36509765198 holds 7 files, 9,743,658 bytes in total.
  • I did not measure the file permissions on shared-model-cache, because I did not look at the cluster.
