+Benchmark: SM103 (B300) FP4 Ultra GEMM vs SM100 (B200) NVFP4 GEMM
+===================================================================
+
+This benchmark compares the performance of the SM103-optimized FP4 Ultra
+GEMM kernel against the SM100 NVFP4 GEMM kernel, both running on B300
+hardware.  It also benchmarks the effect of Programmatic Dependent Launch
+(PDL) on the quant->GEMM pipeline, where the GEMM consumer can begin
+before the quant producer finishes.
+
+SM103 kernels use:
+  - K=768 tile (vs K=256 on SM100)
+  - FP4 Ultra MMA (UltraVs16) schedule
+  - NoSmemWarpSpecialized epilogue
+  - Sm103BlockScaledConfig scale factor layout
+
+PDL kernels additionally set:
+  - cudaLaunchAttributeProgrammaticStreamSerialization on quant (producer)
+  - CUTLASS launch_with_pdl=true on GEMM (enables overlap with next kernel)
+
+Usage:
+    python benchmarks/kernels/benchmark_nvfp4_sm103.py [--mode gemm|quant|e2e|pdl|all]
+
+Requirements:
+    - B300 GPU (SM103 / compute capability 10.3)
+    - CUDA >= 12.9
+    - vLLM built with ENABLE_NVFP4_SM100=1 and SM103 support

-# Editing Agent Instructions
-
-> Read this before modifying `AGENTS.md` or any guide it links to.
-
-## Token Budget Mindset
-
-`AGENTS.md` loads on every agent request; domain guides load on entry to a relevant area.
-Keep `AGENTS.md` under **200 lines** and each domain guide under **300 lines**.
-When a file exceeds its budget, split or prune — do not compress prose to fit.
-
-## When NOT to Add Content
-
-Before writing a new rule, ask whether it is actually needed:
-
- **Agents already do it.** Test with a prompt first. If the agent behaves correctly without the rule, don't add it.
- **One-off incident.** Prefer a code-level fix (lint rule, CI check, test assertion) over a new doc rule.
- **Hardcoded paths.** File paths change; use "search for X" patterns instead.
- **Upstream docs.** Don't reproduce pytest, ruff, or other tool docs — link to them.
- **Contradicts an existing rule.** Search all linked guides before adding. If two rules conflict, consolidate into one.
- **Already covered elsewhere.** Search `AGENTS.md` and every linked guide for overlapping guidance.
-
-If any of the above apply, **do not add the content**.
-
-## Where Content Belongs
-
-The goal is a lean `AGENTS.md` plus rich domain guides that teach agents what they can't learn from the code alone.
-
-| Scope | File |
-| ----- | ---- |
-| Project-wide invariants (contribution policy, env setup, test/lint commands, commit conventions) | `AGENTS.md` |
-| Area-specific knowledge (model patterns, format details, deprecation timelines) | Domain guide |
-
-**Rules of thumb:**
-
- If it only matters for one area, put it in a domain guide.
- If it matters for all areas, consider `AGENTS.md` — but first verify agents don't already do it.
- Create a new domain guide when you have 5 or more non-obvious instructions sharing a coherent scope.
-
-## What Makes a Good Domain Guide
-
-Add what agents can't infer from the code or public docs: project-specific
-conventions that differ from standard patterns, correct approaches that require
-cross-file context, and fixes for repeated mistakes.
-Each entry should be short, specific, and actionable — e.g., which files to
-touch, what order to change them in, and which tests to run.
-
-## Keeping Docs Lean
-
- Every addition should trigger review of surrounding content for stale or redundant items.
- Prefer examples over explanations — a 3-line snippet beats a paragraph of prose.
- Merge related bullets into one principle instead of listing variants.
- Use `search for X` instead of hardcoded file paths.
- PR references are fine in domain guides for traceability, but avoid them in `AGENTS.md`.
-
-## Anti-Patterns
-
-| Pattern | Problem |
-| ------- | ------- |
-| Reactive accumulation | Adding a rule per incident without pruning leads to bloat |
-| Copy-paste between guides | Duplicated content drifts apart; keep in one place, link from the other |
-| Imperative walls | Long DO NOT lists that agents skim past; consolidate into principles |
-| Config snapshots | Show the command to get the value, not the value itself |
-
-## Change Checklist
-
-Before submitting changes to any agent instruction file:
-
- [ ] **Non-obvious?** Would an agent do the wrong thing without this rule?
- [ ] **No conflicts?** Searched all linked guides for contradictions?
- [ ] **Right file?** Project-wide goes in `AGENTS.md`, area-specific in a domain guide?
- [ ] **Offset the addition?** Removed or consolidated something to compensate?
- [ ] **Under budget?** `AGENTS.md` < 200 lines, domain guides < 300 lines?
- [ ] **No hardcoded paths?** Uses "search for X" where paths may change?
- [ ] **Tested?** Verified that an agent actually follows the new instruction?

-# Vision Encoder (ViT) CUDA Graphs
-
-The [CUDA Graphs](cuda_graphs.md) infrastructure in vLLM primarily targets the **decoder** (language model) forward pass. vLLM also supports capturing the **encoder** (vision transformer) forward pass as CUDA Graphs, independently from the decoder. This is based on <https://github.com/vllm-project/vllm/pull/35963>.
-
-!!! note
-    Encoder CUDA Graphs are orthogonal to decoder CUDA Graphs — both can be enabled simultaneously. Encoder graphs capture the vision encoder execution (e.g., ViT in Qwen3-VL), while decoder graphs capture the language model execution as described in the [CUDA Graphs design document](cuda_graphs.md).
-
-## Motivation
-
-Vision encoder inference incurs CUDA kernel launch overhead on the host side. The overhead is more significant when the batch size is small or image size is small.
-
-Encoder CUDA Graphs eliminate this overhead by pre-capturing the full encoder forward pass at multiple token budget levels during model initialization, then replaying the appropriate graph at runtime.
-
-## Design
-
-The encoder CUDA Graph system uses a **budget-based capture/replay** strategy, managed by [EncoderCudaGraphManager][vllm.v1.worker.encoder_cudagraph.EncoderCudaGraphManager]. The system contains the following core components:
-
-* [EncoderCudaGraphManager][vllm.v1.worker.encoder_cudagraph.EncoderCudaGraphManager]: orchestrates capture, replay, greedy packing, and data-parallel execution for encoder CUDA Graphs.
-* [SupportsEncoderCudaGraph][vllm.model_executor.models.interfaces.SupportsEncoderCudaGraph]: a runtime-checkable protocol that models implement to opt-in to encoder CUDA Graphs.
-* [BudgetGraphMetadata][vllm.v1.worker.encoder_cudagraph.BudgetGraphMetadata]: holds the captured CUDA Graph and its associated I/O buffers for a single token budget level.
-
-### Budget-based graph capture
-
-Multiple CUDA Graphs are pre-captured at different **token budget** levels (e.g., `[2048, 4096, 8192, 13824]`). Each budget defines a fixed token capacity, and all budgets share the same maximum batch size (number of images). The `BudgetGraphMetadata` for each level stores the graph along with pre-allocated input, metadata, and output buffers:
-
-```python
-@dataclass
-class BudgetGraphMetadata:
-    token_budget: int
-    max_batch_size: int
-    graph: torch.cuda.CUDAGraph
-    input_buffer: torch.Tensor       # e.g. pixel_values
-    metadata_buffers: dict[str, torch.Tensor]  # e.g. embeddings, seq metadata
-    output_buffer: torch.Tensor      # encoder hidden states
-```
-
-Budgets are auto-generated as power-of-2 levels from a model-provided range via `get_encoder_cudagraph_budget_range()`, with the maximum budget always included even if it does not fall on a power-of-2 boundary. Budgets can also be explicitly specified by the user via `encoder_cudagraph_token_budgets` in `CompilationConfig`.
-
-### Greedy bin-packing at runtime
-
-When a batch of images arrives, the manager sorts images by output token count (smallest first) and greedily packs as many images as possible into each sub-batch while staying within the **largest** token budget and the maximum batch size. Once a sub-batch is finalized (the next image would overflow either constraint), the manager finds the **smallest** budget that fits the sub-batch's total tokens and replays the corresponding CUDA Graph. This repeats until the batch is exhausted. Images that exceed all budgets fall back to eager execution.
-
-For each graph replay:
-
-1. Zero the pre-allocated `input_buffer`, then copy input tensors (e.g., `pixel_values`) into it.
-2. Zero `metadata_buffers`, then slice-copy precomputed values (e.g., rotary embeddings, sequence metadata).
-3. Replay the CUDA Graph.
-4. Clone outputs from `output_buffer` (cloning is necessary since the buffer is reused across replays).
-
-### Data-parallel support
-
-When `mm_encoder_tp_mode="data"`, the manager distributes images across TP ranks using load-balanced assignment via `get_load_balance_assignment`, executes locally on each rank, then gathers results back in the original order via `tensor_model_parallel_all_gather`.
-
-## Model integration via `SupportsEncoderCudaGraph`
-
-Models opt-in to encoder CUDA Graphs by implementing the [SupportsEncoderCudaGraph][vllm.model_executor.models.interfaces.SupportsEncoderCudaGraph] protocol. This protocol encapsulates all model-specific logic so that the manager remains model-agnostic. The protocol defines the following methods:
-
-* `get_encoder_cudagraph_config()` — returns static configuration (supported modalities, input key, buffer keys, output hidden size).
-* `get_encoder_cudagraph_budget_range(vllm_config)` — returns `(min_budget, max_budget)` for auto-inference of token budgets.
-* `get_encoder_cudagraph_num_items(mm_kwargs)` — returns the number of items (e.g. images) in the batch.
-* `get_encoder_cudagraph_per_item_output_tokens(mm_kwargs)` — returns per-item output token counts, used for greedy packing.
-* `get_encoder_cudagraph_per_item_input_sizes(mm_kwargs)` — returns per-item input sizes (e.g. patch counts), used for DP load balancing.
-* `select_encoder_cudagraph_items(mm_kwargs, indices)` — extracts a sub-batch of items by index, used during greedy packing and DP sharding.
-* `prepare_encoder_cudagraph_capture_inputs(...)` — creates dummy inputs for graph capture.
-* `prepare_encoder_cudagraph_replay_buffers(...)` — computes new buffer values from actual batch inputs before replay.
-* `encoder_cudagraph_forward(...)` — forward pass using precomputed buffers (called during capture and replay).
-* `encoder_eager_forward(...)` — fallback eager forward when no graph fits.
-
-Currently supported: **Qwen3-VL** (see `vllm/model_executor/models/qwen3_vl.py`).
-
-!!! note
-    The `SupportsEncoderCudaGraph` protocol is designed to be model-agnostic. New vision encoder models can opt-in by implementing the protocol methods without modifying the manager.
-
-!!! note
-    Encoder CUDA Graphs have currently been tested with `--mm-encoder-attn-backend=FLASH_ATTN` and `--mm-encoder-attn-backend=FLASHINFER` on Blackwell GPUs.
-
-## Configuration
-
-Three fields in `CompilationConfig` control encoder CUDA Graphs:
-
-* `cudagraph_mm_encoder` (`bool`, default `False`) — enable CUDA Graph capture for multimodal encoder. When enabled, captures the full encoder forward as a CUDA Graph for each token budget level.
-* `encoder_cudagraph_token_budgets` (`list[int]`, default `[]`) — token budget levels for capture. If empty (default), auto-inferred from model architecture as power-of-2 levels. User-provided values override auto-inference.
-* `encoder_cudagraph_max_images_per_batch` (`int`, default `0`) — maximum number of images per batch during capture. If 0 (default), auto-inferred as `max_budget // min_budget`.
-
-## Usage guide
-
-Enable encoder CUDA Graphs via `compilation_config`:
-
-```bash
-vllm serve Qwen/Qwen3-VL-32B \
-  --compilation-config '{"cudagraph_mm_encoder": true}'
-```
-
-With explicit budgets:
-

-## Thinking Budget Control
-
-Some models, such as [Qwen3](https://qwen.readthedocs.io/en/latest/getting_started/quickstart.html#thinking-budget), [DeepSeek](https://www.alibabacloud.com/help/en/model-studio/deep-thinking), and [Nemotron3](https://huggingface.co/nvidia/NVIDIA-Nemotron-3-Nano-30B-A3B-BF16), support a thinking budget that limits the maximum number of tokens used for reasoning.
-
-Token counting starts from `reasoning_start_str`. Once the reasoning token count reaches the configured `thinking_token_budget`, vLLM forces the model to produce `reasoning_end_str`, effectively terminating the reasoning block.
-
-To use this feature:
-
- `--reasoning-parser` enables reasoning extraction.
- `--reasoning-config` defines the reasoning boundary tokens (e.g., `reasoning_start_str`, `reasoning_end_str`).
- `thinking_token_budget` (a sampling parameter) sets the per-request reasoning token limit.
-
-If `thinking_token_budget` is not specified, no explicit reasoning limit is applied beyond normal generation constraints such as `max_tokens`.
-
-`--reasoning-config` accepts a JSON object corresponding to  
-[ReasoningConfig][vllm.config.ReasoningConfig] with the following fields:
-
-| Field                 | Type           | Description                                      |
-|-----------------------|----------------|--------------------------------------------------|
-| `reasoning_start_str` | `str \| null`  | String that marks the start of reasoning content |
-| `reasoning_end_str`   | `str \| null`  | String that marks the end of reasoning content   |
-
-!!! note
-    `reasoning_end_str` can include a transition phrase before the reasoning end token. For example, setting `reasoning_end_str` to `"I have to give the solution based on the reasoning directly now.</think>"` instructs the model to emit that phrase when the budget is exhausted, making the reasoning termination more natural.
-
-### Online Serving
-
-```bash
-vllm serve Qwen/Qwen3-0.6B \
-    --reasoning-parser qwen3 \
-    --reasoning-config '{"reasoning_start_str": "<think>", "reasoning_end_str": "I have to give the solution based on the reasoning directly now.</think>"}'
-```
-
-Then make a request with `thinking_token_budget` to limit the reasoning tokens:
-
-```bash
-curl http://localhost:8000/v1/chat/completions \
-  -H "Content-Type: application/json" \
-  -d '{

-    ],
-    "extra_body": {

 If your model is not in the above list, we will try to automatically convert the model using
 [as_seq_cls_model][vllm.model_executor.models.adapters.as_seq_cls_model]. By default, the class probabilities are extracted from the softmaxed hidden state corresponding to the last token.
