What changes

FPM self-service takes a model configuration through profile review, whole-forward timing collection, runtime memory resolution and replay validation without requiring a registered op-level model class. Users select their hardware, precision, TP/DEP/TEP topology and prefill, decode or aggregated serving role; each configuration receives a separate profile, plan and result directory. The canonical FPM self-service guide defines the six stages. Root agent instructions provide the trigger and checkpoint/resume essentials. One revision-checked checkpoint retains investigation, user choices, exact-profile acceptance and artifact references across sessions.

Config and ModelOpt sidecar intake preserve source hashes and unresolved assumptions. Multimodal checkpoints are supported for text-decoder timing, with the non-text scope stated explicitly. Fresh profiles keep memory pending until runtime observations resolve it; users need not invent activation or other non-KV bounds. Ordinary aggregated prediction and recommendation consume the resolved profile through the canonical native performance-model interface and retain strict direct-FPM coverage checks. Independently onboarded prefill/decode roles export worker configuration fragments, not a complete executable P/D deployment.

The self-benchmarking and onboarding guide now follows merged #284's naming and scope and uses aisimulate onboard for new collection. Published Kimi DCP reuse remains a separate consumer path with an explicit build prerequisite; current schema-v7 collection is distinguished from historical schema-v6 reuse. FPM supplies engine-step timings, while Replay provides supported scheduling, routing, P/D transfer and cache behavior; special mechanisms still need corresponding Replay changes.

Runtime memory and collection

onboard probe-runtime uses the existing Kubernetes or caller-owned Slurm executor for bounded probes of the selected role’s required phases. Prefill and decode requests independently retain their accepted graph policy, scheduler limits, memory capacity, artifacts and qualification; deliberate differences between their serving configurations are valid. Explicit aggregated requests pass the same accepted serving configuration to both phase launches, while the runtime may select different execution modes for their batches. Within-role configuration drift and rank inconsistency still reject. Source-audited instrumentation records initialized worker/scheduler settings, physical storage, padding, aliases, group geometry and pool reservations without changing native forwards. The bundled vLLM 0.27.0 adapter and campaign-local vLLM 0.28.0 example retain exact source mappings. Import independently checks their evidence and produces drafts requiring normal profile acceptance. Offline Hugging Face snapshot paths are accepted only when their repository and full immutable revision match the selected checkpoint; source and instrumentation checks remain required.

The native grouped-cache allocator handles full attention, sliding windows and supported convolution storage under one rank-local byte budget, including temporary prefill pages. Profile page_size_bytes aggregates all layers in a semantic group; it is distinct from a runtime layer's padded physical page. Equal physical page sizes do not imply equal aggregate group bytes. Config-only packed minima remain estimates; resolved memory requires actual allocation evidence, while legacy declared bounds remain the caller's conservative declarations.

collect-fpm --check-readiness inspects saved artifacts, and smoke covers every selected cell before full collection. Publication, worker completion, memory readiness and accuracy remain separate. Recovery preserves successful native measurements, failed attempts and immutable campaign identities. Role-scoped --cudagraph-mode, --cudagraph-capture-sizes and --max-cudagraph-capture-size settings remain consistent between probes and formal collection. Role identity survives save/resume, native memory selection, finalization and export; separate campaign/data roots prevent same-topology variants from mixing. Untagged historical requests retain their original serialization, hashes and shared-profile semantics, including the legacy prefill-only override.

Dense decode is classified as synthetic by design only when the native producer's dense_model_content_insensitive skip is corroborated by pinned model/runtime identity, exact supported TP topology and causal full-attention cache evidence. Unsupported sliding, hybrid, convolution or recurrent state and other fallbacks remain ineligible. Qualifying publication records an explicit dense_full_attention_v1 policy and preserves the raw samples. Historical formal pairs keep their saved classification during verification; readiness reaggregation does not silently upgrade them.

Slurm uses a caller-owned allocation, pinned image, explicit mounts and shared campaign paths. The caller chooses job dependencies: independent profiles submit independently, afterany sequences resource use, and afterok represents an actual data prerequisite. New campaigns freeze an editable 16-CPU/cores policy for each node's shared worker/scheduler pool. This is an initial allocation, not an optimum or per-rank pinning. Same-step launcher, worker, scheduler and thread observations verify the actual pool. Changed CPU policies require a fresh campaign; old campaigns remain CPU-unverified.

Quality and validation

onboard finalize verifies the native timing pair and memory evidence, then writes a fresh resolved profile and simulation plan. Optional --collection-report independently verifies and binds the existing report, frozen policy, original request and collection. Manifest and profile provenance retain passed, failed, incomplete or not_assessed, always with accuracy: not_assessed. Failed/incomplete quality permits exploratory use; stale or contradictory provenance rejects. Saved-plan, runtime-profile and replay checks reverify the marker even without a preceding runtime probe. An accepted capacity-only revision can use --memory-config without replacing the original timing identity or implying acceptance of the finalized profile.

Collection validation keeps native validity, execution evidence, independent repeatability and withheld interpolation gates separate. The default v2 policy uses five fresh full-grid launches, maximum two attempts per sample, 5% CV and 5% source-to-median agreement. Each launch uses the existing maximum across ranks; the median is a separate aggregate, and all valid slow samples remain in the population. Bounded subsets remain diagnostic. Holdout selection preserves evidenced execution-mode boundaries without changing ordinary interpolation.

Fresh observation evidence v2 distinguishes requested scheduling from effective worker/native scheduler values and checks producer graph dispatch, token padding, process-local timing and forward indices, and recorded preparation. Missing execution evidence cannot qualify a fresh comparison; contradictory evidence rejects. Historical assessments retain their saved observation version and limited scope. These records do not establish CUDA-event GPU time, complete graph descriptors, kernel identity, equal KV tensors or equivalent cache warming.

Single-role campaigns qualify only their own required phase and export worker.yaml, a role-tagged FPM profile and an isolated systems directory. Collection does not require actual P/D handoff: decode initializes representative state locally. validate-fpm remains aggregated-only and records native direct-query coverage and replay completion separately. Matched serving uses pinned AIPerf, target-tokenized payloads and one compatible complete single-stream play. Only the combined assessment can qualify accuracy for its evaluated configuration and workload. Ordinary exploratory prediction/recommendation remains available with resolved memory and compatible data.

Unconditional shared-path changes

The full branch also changes shared behavior outside the FPM onboarding path:

Path Change and scope
python/aisimulate/src/aisimulate_core/sdk/models/helpers.py Explicit kv_cache_quant_algo: none maps to BF16 KV and retains BF16 FMHA when the effective KV result remains BF16. This affects ordinary SDK metadata callers too. Architecture-specific overrides remain; missing/null metadata retains prior inference.
crates/core/src/engine/scheduler/vllm/core.rs Preemption diagnostics use the lease's resident block count instead of deriving it from logical allocated tokens on all vLLM paths. This changes the PressureEvent count, not victim selection.
python/aisimulate/src/aisimulate/output.py Ordinary output-directory overwrite removes stale fpm-coverage.json alongside the other known outputs. Writing FPM failure coverage remains conditional on FPM evidence.
Shared Rust metrics and replay telemetry Public metrics structs gain optional used/capacity byte fields. Grouped caches report byte occupancy; linear-cache replay omits absent byte fields and retains block metrics. The public Rust struct surface changes even when the optional values are absent.

Targeted coverage includes SDK explicit-none versus missing/null inference, native grouped allocation/eviction/preemption, byte telemetry, profile workflows and query-coverage outputs. Unchanged performance goldens provide limited coverage; they do not prove all shared behavior is identical.

Verification and limits

Latest integration: 34536ecbd541c9a8237cc8685daaf03e10857681, based on reviewed #238 at b946545a2f12bd052c7282714f9d13ef19c36391 and preserving maintainer changes through 4542c81c547db09d74d66b75be76e9c1874eef3c. A fresh native build is paired with the integrated Python sources. The final follow-up changes only two existing test expectations; runtime source and the native binary remain identical to the validated integration at c50b487b.

  • Full package unit/golden run: 11,738 passed, 49 skipped, with one outdated expected-field assertion. The assertion was corrected to retain complete positional-argument checking while including the new keyword-only profile default; all 85 tests in its file pass on the final branch. This covers all 11,739 executed cases across the full run and focused rerun. The 49 skips require external observed-MoE evidence, real Torch, or optional Dynamo components.
  • Required numerical parity: 386 passed (301 engine-step and 85 compile-engine), with incoming data and frozen goldens unchanged. Grouped/query-evidence and serving-validation workflow checks: 292 passed. Focused API checks: 407 passed; Rust FPM checks: 134 passed.
  • Independent review verified both integration fixes: missing collector dependencies produce clean CLI failures without launching workers, and the canonical bs keyword works for native graph and non-graph prefill. Ordinary execution failures retain their readiness reports. Four genuinely saved legacy/aggregated/prefill/decode campaigns resume with every original acceptance, identity, hash and saved byte unchanged.
  • Independent source and behavioral review passed, including re-review of the final test-only correction. Ruff, Python/Rust formatting, whitespace, documentation and ownership checks passed during integration. The broader runs initially blocked by process-inspection permissions were rerun with normal permissions; no runtime workaround or threshold relaxation was added.

This refresh preserves the stricter shared and phase-specific collection bounds, exact runtime-version validation, grouped-cache accounting, serving-role distinctions and interrupted-plan validation. It retains incoming first-token behavior and EngineSpec format 25; older binary EngineSpecs must be regenerated. No GPU recollection or new serving-accuracy claim is part of this integration validation.

The following checks are historical evidence from earlier branch revisions.

Documentation follow-up at d1262e1e: seven documentation-checker tests, destinations in 75 Markdown files, 120 local anchors, 75 Bash examples, embedded Python syntax and onboarding options passed. Independent CPU walkthroughs covered request review/acceptance, planning/preview, TP4/DEP4 profiles, synthetic schema-v7 publication inspection, memory finalization and SDK queries. Both PVC layouts passed all eight prefill/decode smoke/formal generator-input checks. These checks launch no GPU work and establish command/data compatibility, not silicon or serving accuracy.

The Python package unit suite passed 9,874 tests with 11 skips; both required native parity suites passed 386 tests, with no golden changes. Independent task, fix and final whole-branch reviews rerun focused public CLI, profile-selection, grouped-memory, collection, runtime-import, export and compatibility tests. The final review also added native-backed regression coverage for automatic grouped-cache topology suggestions with prefill/decode profiles. Lint, formatting and diff checks pass.

A bounded Slurm validation on eight GB300 GPUs (DEP8 across two four-GPU nodes), using the pinned Inkling-NVFP4 checkpoint and vLLM 0.27.0, passed four phase probes, all three observation imports and checkpoint resume at a4f9c3fa. Independent prefill used PIECEWISE with capture limit 32; independent decode used FULL_DECODE_ONLY with limit 16; aggregated prefill and decode both used FULL_AND_PIECEWISE with limit 32. The runtime was the pinned Dynamo 1.5.0/vLLM 0.27.0 image with audited runtime overlays and campaign-local cache instrumentation. The generated memory profiles remain drafts requiring normal acceptance. Independent audit verified all 64 worker/scheduler observations and 368 artifact references, revalidated all three imports from raw evidence and reproduced their saved memory results. Actual per-point graph-dispatch evidence was unavailable, so this run establishes configuration and import behavior, not timed graph-mode coverage or measurement quality.

Grouped simulation remains cold aggregated vLLM, PP1/CP1, HBM-only and non-speculative, with cross-request prefix reuse disabled. Model and runtime compatibility, missing observations and unsupported layouts remain explicit. This change does not implement P/D handoff or distributed grouped-cache replay, alter timing estimators or accuracy thresholds, or establish GPU measurement stability or serving accuracy. Historical artifacts remain preserved under their original identities.

Explanation

The new prefill_graph_advisory(policy, enforce_eager) contract is not tested. The PR adds three behavior paths in python/aisimulate/src/aisimulate/fpm_advisory.py, and support/fpm.py exposes its result to CLI stderr. No test references the helper or its output. Existing run_fpm tests only assert return values and generated commands, so they do not verify the warning, the runtime suppression path, or the enforce_eager suppression path.

Resolution

Add focused unit tests for prefill_graph_advisory covering explicit policy with and without enforce_eager, and non-explicit policy. Add an integration assertion for run_fpm that checks the warning for a role-less explicit request and confirms suppression for an explicitly selected worker role or eager mode.

Checked 34536ecb for §3c. With --worker-type aggregated the explicit graph configuration is now applied to both probe launches (collector/fpm_forward/runner.py:1255), so the importer's cross-phase compilation_config check is satisfiable by construction, and single-role prefill/decode requests legitimately keep their own policies. Untagged legacy requests keep the old prefill-only behaviour with the pre-GPU warning, which is acceptable given new graph options require a role.

§3c closed. No open findings from my side on this PR.

Inline comments:
Review comments at @crates/core/src/python.rs:
- Around line 2059-2069: Update ReplayCoverageFailure::source to return the next
underlying error in the chain via self.error.source(), rather than returning
self.error itself, so alternate error formatting does not repeat the outer
context.
- Around line 2353-2361: Update the Err branch of the replay_result match so a
failure from replay_fpm_coverage is attached as context to the original replay
error instead of replacing it. Preserve the existing behavior for successful
coverage reads: wrap the replay error with coverage when present, and return the
original error when coverage is absent.
- Around line 1202-1205: In resolve_role_timing and materialize_aic_capacity,
call fpm_resources() only when capacity is not explicit, the backend is Vllm,
and pp is 1; otherwise use no FPM resources. Preserve timing-model construction
and the existing scalar capacity path for ineligible profiles.

Review comments at @python/aisimulate/collector/fpm_forward/config.py:
- Around line 495-505: Update build_collection_plan so aggregated deployments
derive the default max_prefill_isl from the selected deployment’s shared token
limit rather than applying the 8192 cap. When aggregated profiles have different
token limits, require an explicit shared limit and report that requirement
directly; keep the worker_type validation consistent with this behavior.

Review comments at @python/aisimulate/collector/fpm_forward/native_artifact.py:
- Around line 133-144: Update `_zero_kv_prefill_sample` to normalize
`sample_reasons` on both `expected` and each real-prefix `point`, treating
missing or `None` values as empty lists before comparison and removing
`prefill_real_seed` from the real-prefix reasons.

Review comments at @python/aisimulate/src/aisimulate/capacity.py:
- Around line 44-51: Add a Dynamo stack capability check in
materialize_aic_num_gpu_blocks before constructing or passing engine arguments,
and reject profiles containing kv_cache_groups or kv_cache_capacity_bytes with a
clear validation error; keep supported stacks’ grouped-cache behavior unchanged.

Review comments at @python/aisimulate/src/aisimulate/support/runtime.py:
- Around line 549-555: Update runtime_collection_inputs to check
runtime_probe_manifest(request) before calling verify_runtime_profile; when no
manifest exists, return the existing empty-arguments result immediately, and
only verify requests with a probe manifest.

Review comments at @python/aisimulate/src/aisimulate/support/schema.py:
- Around line 98-100: Update SearchProfile context_length handling so 256000
remains a cap rather than an implicit collection max_model_len; in
_request_from_args, require an explicit --context-length when neither a profile
nor model config provides context, and return an actionable error before launch.

Review comments at @python/aisimulate/src/aisimulate/sweeper/config.py:
- Around line 1122-1137: Update the deployment-mode loops that call
_fpm_parallel_configs so a mode with missing role deployments is skipped without
preventing other compatible modes from being processed; in enumerate_branches,
handle the unavailable-mode error around the _fpm_parallel_configs call as well.
Alternatively, validate deployment_mode up front and clearly report that it must
match the profile’s available roles.

Review comments at @python/aisimulate/src/aisimulate/sweeper/kv_load.py:
- Around line 255-277: Update the grouped-layout capacity handling around
`_role_grouped_capacity` so grouped candidates follow one consistent metadata
contract: either document and update consumers to use the byte-based
`capacity_bytes` data, or explicitly define token-capacity metadata as optional.
Ensure consumers do not unconditionally read `kv_load_capacity_tokens` or
`agg_kv_capacity_tokens` when `role_capacity_tokens` is empty.

Review comments at @python/aisimulate/src/aisimulate/sweeper/replay.py:
- Line 356: In EngineReplayRunner.run, normalize flat ReplaySpec engine
arguments using the same logic as runner.py before calling require_compatible or
selecting the profile deployment, so topology, precision, and worker-role
filters apply when timing_model is absent. Add boundary tests confirming a flat
linear selection is accepted and a flat grouped selection is rejected.

Linked repositories findings

ai-dynamo/dynamo

Inspected ref b102820 on open PR #15110’s branch.

  • Dynamo pins Python aisimulate==0.12.0 and Rust aisimulate-core = "=0.12.0"; consistency tests require matching published releases and lockfile checksums. New APIs require coordinated release/version updates. [::ai-dynamo/dynamo::]
  • MockEngineArgs JSON deserialization uses deny_unknown_fields and has no grouped-cache fields, so kv_cache_groups or kv_cache_capacity_bytes payloads would be rejected. lib/mocker/src/common/protocols.rs:424 [::ai-dynamo/dynamo::]
  • Replay lowering calls materialize_aic_num_gpu_blocks, then computes capacity exclusively as num_gpu_blocks * block_size; byte-only grouped-cache capacity is not represented in this integration. components/src/dynamo/replay/config.py:27-39, components/src/dynamo/replay/simulation.py:504-513 [::ai-dynamo/dynamo::]

ai-dynamo/aiconfigurator

Inspected ref f254959, the frozen compatibility reference.

  • The Rust compatibility API asserts ENGINE_SPEC_SCHEMA_VERSION == 15, while this PR reports retaining EngineSpec format 25. Existing serialized specs therefore require regeneration or a coordinated consumer update. aic-core/rust/aiconfigurator-core/src/config.rs:17,72, aic-core/rust/tests/public-api/src/lib.rs:62,85 [::ai-dynamo/aiconfigurator::]
  • Its documented and tested memory contract remains scalar: estimate_num_gpu_blocks converts total_kv_size_tokens using scheduler_block_size; no grouped byte-budget contract is present. tests/integration/test_memory_estimation.py:173-201 [::ai-dynamo/aiconfigurator::]

Brings in the FPM decoupling / self-service onboarding stack (ai-dynamo#238, ai-dynamo#248,
ai-dynamo#347), the output adapters (ai-dynamo#334) and the CI changes (ai-dynamo#349, ai-dynamo#351, ai-dynamo#353,
ai-dynamo#354, ai-dynamo#330, ai-dynamo#319).

Conflict resolutions:

- ENGINE_SPEC_SCHEMA_VERSION: upstream claimed 25 for the FPM decoupling
  selector; decode CP is renumbered to 26 (positional dcp_size tails on the
  attention / MLA / DSA ops). Stale-payload loops reject 20..25; the 25
  payload keeps the selector like the decoupling branch's 21.
- cp_size: upstream added a CP1-only `cp_size` to compile_engine,
  estimate_kv_cache / estimate_num_gpu_blocks, EngineBuildRequest and the
  legacy Rust compile path ("this SDK entry point does not support context
  parallelism"). This branch supports prefill CP at exactly those entry
  points, so the duplicate parameters / struct field are folded into ours,
  the CP1 gates become positive-integer validation, and the FPM profile cell
  selection receives the real cp_size (a profile without that cell fails
  loud with "no matching FPM deployment profile"). Upstream's tests are
  adjusted accordingly.
- FpmCompileConfig / AicTimingConfig parallel-shape checks combine
  upstream's `fpm_profile.is_none()` exemption with the `* cp_size` fold;
  aic_capacity_kwargs gains cp_size / dcp_size; fpm best_available keeps
  upstream's registered-architecture check ahead of the DCP mode gate.
- capacity.py worker resolution carries aic_cp_size / aic_dcp_size next to
  aic_fpm_profile / worker_type.
- ParallelismPresetConfig.prefill_context becomes Optional (None = 1), like
  decode_context, so default parallelism dumps carry no CP keys; the new
  onboarding topology tests (ai-dynamo#248) compare those dumps against the
  six-key request parallelism. Consumers read it through compiler._prefill_cp.
