Summary

  • Add CPT pipeline definitions for rhaiis (cpt.d/cpt.yaml): defines 4 pipelines — cpt-vllm-release, cpt-sglang-competitive, cpt-trtllm-competitive, and cpt-vllm-competitive — each with a model/workload matrix for automated cross-engine performance testing via the Fournos UI.
  • Fix model config: add kv-cache-dtype: fp8 to llama-3-3-70b-fp8 in models.yaml.
  • Update ci-test preset: enable tests.rhaiis.run_benchmark so CI test runs actually execute the benchmark.
  • Refactor Slack notifications: extract duplicated user-line formatting into _format_slack_user_line() and add support for Slack user group IDs (<!subteam^...> mentions).

CPT Pipelines

Pipeline Engine Models Workloads
cpt-vllm-release vLLM 9 (Tier 1, incl. tp2 variants) ci-quick, profile1–4
cpt-sglang-competitive SGLang 7 (Tier 1) profile1–4
cpt-trtllm-competitive TensorRT-LLM 3 (NVIDIA-only) profile1–4
cpt-vllm-competitive vLLM 12 (wide coverage) profile1–4

Test plan

  • Trigger a cpt-vllm-release pipeline run from the Fournos UI and confirm jobs are generated for the expected model×workload matrix
  • Verify Slack notifications correctly format user group mentions (<!subteam^...>)
  • Confirm llama-3-3-70b-fp8 picks up the new kv-cache-dtype: fp8 arg in a ci-test run

Summary by CodeRabbit

  • New Features

    • Added continuous performance testing pipelines for vLLM, SGLang, and TensorRT-LLM, with configurable models, workloads, benchmarking, profiling, dashboards, and Slack notifications.
    • Enabled benchmark execution for the CI test workload.
  • Improvements

    • Improved Slack notification formatting for triggered-by information.
    • Enabled FP8 key-value cache configuration for the Llama 3.3 70B FP8 model.
    • Added documentation for CPT configuration and job submission.
  • Bug Fixes

    • Corrected pod log artifact filenames to ensure logs are captured and uploaded.
    • Corrected GuideLLM latency reporting to preserve accurate median and p95 values.

📝 Walkthrough

Walkthrough

The change adds four CPT pipeline definitions, enables benchmark execution, configures FP8 KV caching, centralizes Slack formatting, corrects pod log filenames, and preserves GuideLLM latency values in seconds.

Changes

Orchestration configuration

Layer / File(s) Summary
CPT pipeline and runtime configuration
projects/rhaiis/orchestration/cpt.d/cpt.yaml, docs/fournos-ui/cpt-config-structure.md, projects/rhaiis/orchestration/presets.d/presets.yaml, projects/rhaiis/orchestration/config.d/models.yaml
Adds four CPT pipelines, documents CPT configuration and submission flow, enables benchmark execution for ci-test, and sets FP8 KV-cache configuration for llama-3-3-70b-fp8.

Slack notifications

Layer / File(s) Summary
Slack trigger formatting
projects/rhaiis/postprocess/regression.py
Adds shared formatting for Slack user IDs, group IDs, plain display names, and blank values. Applies it to regression, success, and failure notifications.

Pod log artifacts

Layer / File(s) Summary
Pod log filename alignment
projects/rhaiis/orchestration/test_phase.py, projects/rhaiis/toolbox/capture_isvc_state/main.py
Uses .log filenames for predictor, current pod, and previous pod logs.

GuideLLM parsing

Layer / File(s) Summary
Request latency unit handling
projects/guidellm/postprocess/guidellm/parsing/parsers.py
Keeps request latency median and p95 values in seconds without dividing them by 1000.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to c7367

The new CPT documentation gives conflicting guidance about cluster selection, generated job counts, and null model entries, which could cause incorrect benchmark jobs or missing runtime settings. The PR should clarify these contracts before merge.

@Harshith-umesh I don't understand what this is supposed to be? 🤔 presets don't work this way, do they?

GuideLLM stores request_latency as end_time - start_time (seconds),
unlike the _ms fields (TTFT, ITL, TPOT) which are in milliseconds.
Dividing by 1000 produces values ~1000x too small.

- Around line 91-92: Update the launcher argument-resolution documentation to
define the positional roles explicitly: resolve the cluster argument such as
hera through presets.d/clusters.yaml, and resolve only the remaining preset
arguments through presets.d/presets.yaml, merging those preset overrides
left-to-right. Align the affected example with the existing cluster and preset
handling described elsewhere in the document.
- Around line 162-163: Clarify the job-count terminology in the CPT pipeline
documentation: distinguish 45 model/workload combinations from 9 submitted
FournosJobs when each job processes all workloads. Update the example near the
matrix definition and align the related explanations and CLI launcher guidance
so they consistently use these definitions.
- Around line 137-139: Clarify the null model-entry semantics in the
configuration documentation: null or omitted means no additional per-model
overrides, while the preset key still resolves the model preset and
tensor-parallel size and pipeline-level globals remain applied. Explicitly
preserve the launcher requirements for tests.rhaiis.model_key and gpuCount,
consistent with the null-entry example.

If the value is `null` (or omitted), only the pipeline-level globals apply.
If the value is a map, those entries are additional config overrides for that
specific model (e.g. to override `tensor-parallel-size`):

Clarify null model-entry semantics.

Line [137] says that a null or omitted value applies only pipeline-level globals. However, the <preset>/tp<N> key still resolves the model preset and tensor-parallel size. Lines [143]-[145] explicitly show a null entry using the model default TP. Define null as “no additional per-model overrides” so a launcher does not omit tests.rhaiis.model_key or gpuCount.
