Real Triton MoE up-projection with SwiGLU activation — fused grouped matmul + gate * up element-wise. No torch.bmm / torch.einsum fallback, no library kernel calls. Looks fine.
audited by hand — see results/annotations/ for the full schema.
Implemented the custom Triton grouped GEMM + fused SwiGLU path in [solution.py](/home/infatoshi/cuda/KernelBench-Hard/problems/06_sonic_moe_swiglu/solution.py). The kernel launches one tile per `(expert, M tile, I tile)`, reads `expert_offsets` for the expert slice, accumulates both gate and up projections in fp32 from bf16 inputs, applies `silu(gate) * up` in the epilogue, and stores bf16. I tuned the tile choices for the required shapes: - Small shape uses `BLOCK_M=64, BLOCK_N=128, BLOCK_K=32`, `4` warps, `3` stages. - Larger 2048-row/expert shapes use `BLOCK_M=256, BLOCK_N=64, BLOCK_K=32`, `8` warps, `3` stages. - No forbidden ops are present in `solution.py`. **Verification** - `uv run check.py`: `PASS` - `uv run benchmark.py`: `RESULT: OK` - shape 0 solution: `41.216 TFLOPS`, `20.008 ms`, peak fraction `0.2061` - shape 1 solution: `75.308 TFLOPS`, `0.456 ms`, peak fraction `0.3765` - shape 2 solution: `40.826 TFLOPS`, `13.466 ms`, peak fraction `0.2041` - geomean `peak_fraction: 0.2511` - `uv run ruff check . --fix`: passed - `uv run pytest tests` from repo root: `10 passed` One caveat: plain `uv run pytest` is not a clean signal in this repo right now. From the problem directory it collects zero tests and exits with pytest code 5; from the repo root it tries to collect unrelated historical scratch tests under `outputs/runs/...` and fails during collection before reaching the checked-in test suite. The checked-in `tests/` suite passes.

<permissions instructions> Filesystem sandboxing defines which files can be read or written. `sandbox_mode` is `danger-full-access`: No filesystem sandboxing - all commands are permitted. Network access is enabled. Approval policy is currently never. Do not provide the `sandbox_permissions` for any reason, commands will be rejected. </permissions instructions> <apps_instructions> ## Apps (Connectors) Apps (Connectors) can be explicitly triggered in user messages in the format `[$app-name](app://{connector_id})`. Apps can also be implicitly triggered as long as the context suggests usage of available apps. An app is equivalent to a set of MCP tools within the `codex_apps` MCP. An installed app's MCP tools are either provided to you already, or can be lazy-loaded through the `tool_search` tool. If `tool_search` is available, the apps that are searchable by `tools_search` will be listed by it. Do not additionally call list_mcp_resources or list_mcp_resource_templates for apps. </apps_instructions> <skills_instructions> ## Skills A skill is a set of local instructions to follow that is stored in a `SKILL.md` file. Below is the list of skills that can be used. Each entry includes a name, description, and file path so you can open the source for full instructions when using a specific skill. ### Available skills - imagegen: Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas. (file: /home/infatoshi/.codex/skills/.system/imagegen/SKILL.md) - openai-docs: Use when the user asks how to build with OpenAI products or APIs and needs up-to-date official documentation with citations, help choosing the latest model for a use case, or model upgrade and prompt-upgrade guidance; prioritize OpenAI docs MCP tools, use bundled references only as helper context, and restrict any fallback browsing to official OpenAI domains. (file: /home/infatoshi/.codex/skills/.system/openai-docs/SKILL.md) - plugin-creator: Create and scaffold plugin directories for Codex with a required `.codex-plugin/plugin.json`, optional plugin folders/files, and baseline placeholders you can edit before publishing or testing. Use when Codex needs to create a new local plugin, add optional plugin structure, or generate or update repo-root `.agents/plugins/marketplace.json` entries for plugin ordering and availability metadata. (file: /home/infatoshi/.codex/skills/.system/plugin-creator/SKILL.md) - skill-creator: Guide for creating effective skills. This skill should be used when users want to create a new skill (or update an existing skill) that extends Codex's capabilities with specialized knowledge, workflows, or tool integrations. (file: /home/infatoshi/.codex/skills/.system/skill-creator/SKILL.md) - skill-installer: Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos). (file: /home/infatoshi/.codex/skills/.system/skill-installer/SKILL.md) ### How to use skills - Discovery: The list above is the skills available in this session (name + description + file path). Skill bodies live on disk at the listed paths. - Trigger rules: If the user names a skill (with `$SkillName` or plain text) OR the task clearly matches a skill's description shown above, you must use that skill for that turn. Multiple mentions mean use them all. Do not carry skills across turns unless re-mentioned. - Missing/blocked: If a named skill isn't in the list or the path can't be read, say so briefly and continue with the best fallback. - How to use a skill (progressive disclosure): 1) After deciding to use a skill, open its `SKILL.md`. Read only enough to follow the workflow. 2) When `SKILL.md` references relative paths (e.g., `scripts/foo.py`), resolve them relative to the skill directory listed above first, and only consider other paths if needed. 3) If `SKILL.md` points to extra folders such as `references/`, load only the specific files needed for the request; don't bulk-load everything. 4) If `scripts/` exist, prefer running or patching them instead of retyping large code blocks. 5) If `assets/` or templates exist, reuse them instead of recreating from scratch. - Coordination and sequencing: - If multiple skills apply, choose the minimal set that covers the request and state the order you'll use them. - Announce which skill(s) you're using and why (one short line). If you skip an obvious skill, say why. - Context hygiene: - Keep context small: summarize long sections instead of pasting them; only load extra files when needed. - Avoid deep reference-chasing: prefer opening only files directly linked from `SKILL.md` unless you're blocked. - When variants exist (frameworks, providers, domains), pick only the relevant reference file(s) and note that choice. - Safety and fallback: If a skill can't be applied cleanly (missing files, unclear instructions), state the issue, pick the next-best approach, and continue. </skills_instructions>

# AGENTS.md instructions for /home/infatoshi/cuda/KernelBench-Hard/problems/06_sonic_moe_swiglu <INSTRUCTIONS> # Global Agent Instructions ## Python UV is the ONLY way to run Python. No exceptions. - `uv run script.py` (not `python script.py`) - `uv pip install` / `uv add` (not `pip install`) - `uv venv` (not `python -m venv`) Never use `--system`. Never use bare `python`/`pip` commands. ## Testing Tests are MANDATORY for all implementation work. - Run tests: `uv run pytest` - Run linting: `uv run ruff check . --fix` - Both must pass before work is complete Comparison rules: - Integers/exact: bitwise comparison (`==`) - Floats: `atol`/`rtol` tolerance (IEEE 754 limitations) ## Restrictions - No emojis in code or comments - No em dashes - Never guess performance numbers - benchmark or say "needs measurement" - Do not over-engineer - minimal changes only - Do not add features beyond what was requested - Do not refactor unrelated code ## Verification Protocol Before completing ANY task: 1. Re-read the original request. Does your work fully address it? Not partially -- fully. 2. If you wrote or modified code, execute it. Verify the output matches expectations. 3. If tests exist, run them. If you made non-trivial changes and no tests exist, write them. 4. Review your last several tool outputs for unaddressed errors, warnings, or failures. 5. If you edited a file 10+ times without resolving the issue, stop and try a fundamentally different approach. Do NOT declare completion until all checks pass. ## Environment Discovery At the start of complex tasks, map the environment: - Check what's installed (uv, python version, key packages) - Check git state (branch, dirty files, recent commits) - Check disk space if doing large builds - Read SPEC.md if it exists ## GPU (Shared Machine) Before running ANY GPU workload (training, inference, profiling, benchmarking, kernel compilation), check `nvidia-smi` to verify GPU utilization is low enough to proceed. Multiple people share this machine. If the GPU is already in use (>10% utilization or significant memory allocated), do NOT launch your workload -- report the conflict and wait for instructions. ## Machines - local/macbook: MacBook Pro M4 Max (14c: 10P+4E), 36GB unified, Metal 3, macOS 26.3 - anvil: Ryzen 9 9950X3D (16c/32t), 92GB DDR5, RTX PRO 6000 Blackwell Workstation 96GB (sm_120, 600W TDP), 3.6TB NVMe, Ubuntu 24.04, CUDA 13.2 + nvcc 12.8, Driver 595.58.03 (hostname: anvil, formerly theodolos) ## Google CLI (gogcli) Binary at /usr/local/bin/gog.

Note: `batch` panics in v0.5.4, skip it. ## Project Context Files When creating or updating project-level CLAUDE.md or AGENTS.md files: **Include:** version pins, build/run/test commands, behavioral overrides, undiscoverable context (company/hardware/API configs), current status, domain gotchas, hard constraints the model gets wrong without being told. **Exclude:** directory trees (discoverable), architecture narration, feature specs (use SPEC.md), enum/type definitions from code, workflow docs, general coding principles, anything findable in <60s. If something keeps breaking or you hit the same mistake twice, add the fix to the project AGENTS.md/CLAUDE.md so future sessions don't repeat it. Fewer constraints with higher signal beats comprehensive documentation. --- project-doc --- # KernelBench-Hard — Developer Instructions (codex / droid) This is the codex / droid / cursor-agent equivalent of `CLAUDE.md`. Content is identical; format is plain markdown for any CLI. See [`CLAUDE.md`](./CLAUDE.md) for the canonical version. All rules there apply. Summary of the non-negotiables: - **uv only.** `uv run ...`, `uv add ...`, `uv pip install ...`. Never `pip` or bare `python`. - **Before committing:** `uv run ruff check . --fix && uv run pytest`. - **Do not edit `problems/*/solution.py`** — those are agent output. - **Do not modify `reference.py`, `check.py`, `benchmark.py`, `problem.yaml`, `shapes.py`, or `PROMPT.txt`** of an already-published problem. - **Apply the torch 2.11 inductor CSE hotfix** via `./scripts/patch_torch.sh` after any `uv sync`. ## Quick actions ```bash uv sync ./scripts/patch_torch.sh ./scripts/run_hard.sh claude claude-opus-4-7 problems/01_fp8_gemm ``` ## Repo layout and adding a new problem See `CLAUDE.md` — everything there is authoritative. </INSTRUCTIONS> <environment_context> <cwd>/home/infatoshi/cuda/KernelBench-Hard/problems/06_sonic_moe_swiglu</cwd> <shell>zsh</shell> <current_date>2026-04-28</current_date> <timezone>America/Edmonton</timezone> </environment_context>

I need you to write the up-projection of a top-K MoE FFN with grouped GEMM and fused SwiGLU for the RTX PRO 6000 (SM120 Blackwell, GDDR7, 1.8 TB/s). The reference implementation is in reference.py and your kernel goes in solution.py. You can make whatever mess you want in this directory — scratch files, intermediate kernels, build artifacts, profiling traces — but the final answer has to be in solution.py with the same Model, get_inputs, and get_init_inputs interface as reference.py. The op is: per expert e, compute h_e = silu(x_e @ W_gate[e]) * (x_e @ W_up[e]) where x_e is the slice of permuted hidden states routed to expert e. Inputs are hidden_states of shape (T_perm, H) bf16 (already permuted into expert order, T_perm = T_total * K), expert_offsets of shape (E+1,) int32 (prefix sums of token counts per expert, so expert e owns rows [offsets[e]:offsets[e+1]]), and per-expert weights W_gate and W_up each of shape (E, H, I) bf16. You return gated_up of shape (T_perm, I) bf16. Correctness tolerance is 0.02 abs/rel on bf16. The shapes you have to handle are T_total=32768 H=4096 I=1536 E=128 K=8 (the headline sonic-moe configuration, 32K tokens, 128 experts, top-8), T_total=4096 H=2048 I=1024 E=64 K=4 (smaller / faster iteration), and T_total=16384 H=2048 I=4096 E=64 K=8 (intermediate-heavy aspect ratio that forces larger N tiles). This needs to be a real custom kernel — the whole point is to implement the variable-length grouped GEMM and fuse SwiGLU into the epilogue, not to dispatch to a vendor library. Don't import or call torch.matmul, torch.bmm, torch.nn.functional.linear, F.linear, or anything from sonic_moe. Try CUTLASS grouped GEMM (the intended path), Triton with a grouped-GEMM autotune, CUDA C++ via load_inline, or inline PTX — your call. Anything you're uncertain about, look up PTX docs, clone CUTLASS or sonic-moe or quack-kernels or other reference repos, read library headers, and investigate. Your flywheel is implement, profile (ncu, nsys, torch.profiler — whatever's useful) and time it with benchmark.py, verify correctness by running `python check.py` and reading the output, then iterate. Don't substitute your own one-off correctness snippets for check.py — it iterates over every shape, your spot-check almost certainly won't. If `python check.py` hasn't printed PASS, you're not done. Take as long as you need to actually push the number up.

**Considering code execution** I’m thinking about how to run inline code. It seems I might be able to use `uv run python - <<`, but I should definitely proceed with caution. It’s essential to gather my current working directory, git status, and UV version first. That way, I can set up everything properly. I want to ensure I understand what I’m doing before diving in, just to avoid any potential mishaps!
assistant
I’ll first map the local problem harness and environment, then inspect the reference and existing solution shape before touching `solution.py`. I’ll also check GPU state before any correctness or benchmark run, since the check harness will compile and execute CUDA work.

**Checking files and packages** I need to inspect some files and check key packages, including the torch version. I think I should run a command like `uv run python -c "import torch, triton"` since I used `uv run -- python --version` before. That seems good for my context. I also want to run `nvidia-smi` before working on the GPU, but I'm not there yet. Besides that, I need to read through the files and check for reference.py and solution.py. I might need to use parallel processing too.
assistant
The repo is clean on `master`, there’s plenty of disk, and the problem directory has the expected harness files. Next I’m reading the exact reference interface and shape generator so the solution stays compatible with the harness.

**Optimizing output format** I see that the reference returns an output assigned as bf16. I'm thinking to better match that output: maybe after applying the gate and the up dot, I should convert to bf16 and then use the silu/mul operation? That could help ensure everything aligns correctly. It's all about keeping things consistent and efficient! Let's see if this approach works better for what I'm intending to achieve.
assistant
The harness creates balanced per-expert batches for all three required shapes, but I’ll still use `expert_offsets` for row ranges so the kernel is not hardwired to one layout. Torch 2.11 and Triton 3.6 both see `sm_120`, and the GPU is idle enough to run checks.

"""Centralized GPU timing for benchmark.py files.

All problems' benchmark.py should call `time_fn` from here so we have one

Methodology:
  - 10 warmup calls absorb Triton autotune (typical ~7 configs) and
    torch.compile reduce-overhead CUDA-graph capture.
  - Between each timed call, `_l2_flush()` writes 128 MB to evict L2
    (Blackwell L2 is 96 MB; we want any prior L2 contents flushed so
    we measure HBM-load bandwidth, not L2-cached bandwidth).
  - GPU timing via cuda.Event with synchronize() AFTER record() but
    BEFORE elapsed_time() — the canonical NVIDIA pattern.
  - Reported value is the median of `iters` trials, robust to outliers.

Notes / known biases not addressed here:
  - torch.compile(mode="reduce-overhead") gets CUDA graphs which eliminate
    launch overhead. Custom Triton/CUDA kernels do NOT get this treatment.
    On small shapes where launch overhead matters, this gives compile an
    artificial advantage. We accept this as the cost of using the agreed
    "compiled" baseline policy.
  - cuBLAS / cuDNN allocate workspaces on first call. 10 warmup absorbs.
  - Median over a fairly small number of trials (default 30) is fine for
    headline numbers but won't catch bimodal distributions. Use --extra
    instrumentation if you ever care.

I’m going to put in a Triton kernel first: one program computes a `(rows x columns)` output tile for one expert, accumulates gate and up projections in fp32 from bf16 inputs, applies SwiGLU in the epilogue, and stores bf16. After it passes `check.py`, I’ll tune tile sizes against `benchmark.py`.

`solution.py` now has the first real custom path and does not rely on a library GEMM call. I’m going to run the harness next; if it fails, the failure mode will tell whether we need a correctness adjustment or just tile/config tuning.

**Assessing GPU performance** I’m considering that it might be too slow based on how significant the shape and three seeds are. This can take minutes. I should probably monitor the process using nvidia-smi. I wonder if I can use something parallel? Since a session is already running, I think I could execute the nvidia command to check if the GPU workload is running fine. Let's keep an eye on that!
assistant
The full check is still running after the first minute and a half. Given the reference workload size, I’m going to check GPU utilization separately to make sure it is making progress rather than hanging.

**Troubleshooting GPU Utilization** I'm looking at the GPU utilization being at 0, which makes me wonder if it's due to CPU compilation or something else. Memory seems high, and I’m considering if there's a reference loop happening, but it doesn't appear like that right now. I’m also curious if it could be that the system is compiling Triton. I might need to poll and check further to clarify what’s going on.

**Preparing for benchmarking** I need to establish a benchmark first. Before diving into GPU workload, I should check `nvidia-smi` to gather the necessary details. Once I've done that, I can run the benchmark, which could take some time. I plan to use the command `uv run benchmark.py`. It might be a good idea to compare the results afterward too, for a better understanding of performance.
assistant
Correctness passed across the harness shapes and seeds. I’m moving to `benchmark.py` now so the next edits are driven by measured throughput rather than guesses.

Benchmark output has started; the warning is from compiling the Python reference, not from `solution.py`. I’m waiting for the measured shape lines before changing tile sizes.

**Tuning performance benchmarks** The benchmark passes the threshold, but the user wants to push the number up, so I need to tune it. It seems our solution is slower than the reference for large shapes, possibly even lower than eager PyTorch loops with cuBLAS. I need to improve performance through iterations, adjusting block sizes, and maybe creating a scratch benchmark script that uses just UV and checks with nvidia-smi before GPU operation. Considering using Triton’s autotune, but I should also measure the candidates since the solution could accept dynamic configs. I may implement multiple kernels with different block shapes in Triton based on dimensions. **Optimizing the kernel performance** Instead of manually editing solution.py over and over, I’m considering creating a scratch script with alternative kernels. Perhaps I could use the existing kernel but with different block arguments, something like scratch_tune.py. However, tweaking solution.py directly might be easier. I need to optimize to ensure we surpass the baseline. My kernel combines two matrix multiplications into one program, but I wonder if register pressure or activation expansion is causing slowdowns. It looks like we're hitting an actual peak of 200 TF, which matches our declared peak, so that’s good! The reference reports an actual of 268 TF, potentially because of cuBLAS. Maybe there's a glitch in the benchmark formula? I could also try reducing time in shape0/2 to improve those reported numbers. **Exploring performance improvements** If the hardware can exceed 200 TF, then perhaps there's potential for improvement. My current per tile performance is around 200 TF, but I need to aim higher to match the reference performance of 268 TF reported by cuBLAS loops. Better tiling might help, so tuning is essential. I see potential bottlenecks in combining both operations in one kernel. If I used separate matrix multiplications, I could leverage cuBLAS for the 268 TF along with a separate activation step. However, that’s not allowed for the solution, so maybe I can create a custom Triton setup with two separate kernels? **Running GPU commands** I need to use nvidia-smi first to check the GPU status. I don’t think I need to write a scratch file since the user has allowed it. I’ll use apply_patch for file modifications. But I’m wondering if shell heredoc is appropriate for scratch. It seems like I should avoid creating or editing files with cat, so I'll stick to using apply_patch for manual code edits.
assistant
The first pass is correct and already clears the benchmark threshold, but the large shapes are behind the cuBLAS-backed reference timings. I’m going to tune the Triton tile geometry next, mainly larger `N` tiles and different row tile sizes to improve tensor-core utilization and reduce repeated `x` loads.

**Prioritizing tasks** Okay, I need to focus on running `nvidia-smi` first before getting to `ruff`. It looks like that's the order of operations — checking the GPU status is crucial for performance tuning. I'll make a note of that. So, I’m preparing to execute the necessary commands, ensuring everything's ready for later. I want to stay organized and make sure I don't miss anything!

**Considering process execution** It seems like the process I'm running is taking a long time. I wonder if it's due to creating large configurations and not outputting anything because of buffering. Maybe I should interrupt it? Alternatively, using the '-u' option might help. I think the process will eventually finish, but I might need to check with `nvidia-smi` to see how it's performing. I'm curious if there’s a better way to approach this situation!

**Troubleshooting script performance** I’m trying to figure out why the patch tune script isn't producing output. Maybe it has to do with the print function being buffered or because the first configuration took too long—over 5 minutes seems excessive! It might also relate to large allocations of shape0 weights that aren’t being freed. I wonder if the compile process is slow or stuck due to certain configurations. I might consider using an unbuffered approach and reducing the number of configs to speed things up. **Optimizing patch tuning** I’m thinking about how to optimize patch tuning with a focus on flushing and starting with smaller shapes, probably around the current config. I might not need to patch if manually editing works with benchmarks. Testing one config with a small script and using a timeout sounds good too. I’m considering creating a parameterized tune_one.py or adapting the current patch. I’ll flush outputs and avoid unnecessary lists when applying patches, maybe reusing the model and inputs per shape to streamline the process. **Restructuring model allocation** I’m realizing that the current setup allocates models per configuration, which is expensive but not to the point of taking minutes. To improve efficiency, I should restructure it to allocate once per shape and then pass that to the run config, which should help reduce costs. I need to create a patch file and use apply_patch for the changes. Maybe incorporating garbage collection could help too. Let’s focus on patching to allocate per shape once and loop through configurations.

The sweep found a clear improvement: `BLOCK_M=64, BLOCK_N=64, BLOCK_K=64` is much faster for shapes 0 and 1, and the wider `N=128` variants exceed the shared-memory budget at `num_stages=4`. I’m waiting for shape 2, then I’ll bake in the best per-shape choice.

`64x64x64` cuts the large-shape kernel time by roughly a quarter in the quick sweep. I’m doing one more targeted sweep with lower pipeline stages for wider column tiles and a larger row tile, because those are the plausible remaining wins under the shared-memory limit.

The targeted sweep is better: shape 0 likes `128x64x64` with 8 warps, while shape 1 likes `64x128x64` with 3 stages. I’m waiting on shape 2 before deciding whether the final code should branch per shape.

**Evaluating GPU performance** I'm considering that if `.item()` includes GPU reductions before launch, it might be measuring the max kernel on the GPU with CPU synchronization. It seems like there's an event recorded where PyTorch operations are enqueued. That syncs the host until the max operation is done, and then Triton launches. The elapsed time for the event includes the max GPU time, which could be just a few microseconds. However, I'm worried that Python sync calls could affect performance, especially with smaller shapes. Maybe using known shapes and a balanced approach could help improve performance? **Deciding on file management** I’m thinking about whether I should keep the scratch file when finalizing the answer called "solution.py." The instruction mentioned that I can make a mess, which feels reassuring. So, I might leave the scratch file as it is, just in case I need to reference it later or if anything changes. That's a nice option to have, and it keeps my process a bit flexible!

I’m updating `solution.py` to use the measured tile choices: larger row tiles for the 2048-row expert case, and wider column tiles for the smaller and intermediate-heavy shapes. The branch keys are the dimensions the harness passes to `Model`, not benchmark-only state.

Benchmark is in the reference compile section again; the warning is the same reference graph break. I’m waiting for the final shape lines.

The tuned version is now faster than the eager and compiled reference on every benchmark shape: geomean peak fraction moved from `0.1551` to `0.2372`. I’m doing one final narrow sweep around the current winners to see whether row-128/column-128 or lower-stage variants buy anything more before I freeze the file.

The final sweep found small extra wins: shape 0 improves with `256x64x32`, and the small shape improves slightly with `64x128x32` at 3 stages. I’m waiting for shape 2 before applying that last set.

One more targeted result is worth checking before finalizing: the best current tile uses a very large row block, so I’m going to test adjacent variants with fewer stages or wider columns to make sure the official branch is not leaving an obvious win on the table.

**Evaluating shape parameters** I’m considering the best shape for my stage 3, looking at parameters like 64, 128, 32, 4, and 3. I think a patch solution might help, but I need to verify my benchmark results. It’s essential to check if the official specs might differ from what I've been using. I want to make sure I'm on the right path to get optimal performance and accuracy!
assistant
The adjacent sweep confirms the final branch: `256x64x32` with 8 warps and 3 stages for the 2048-row experts, and `64x128x32` with 4 warps and 3 stages for the small shape. The wider `256x128` tile is pathological, so I’m excluding it.

**Fixing code issues** I need to fix some code issues. My first thought is to delete the `scratch tune_tiles.py` file. It might be better to remove that completely and then apply the patch deletion. After that, I should rerun `ruff`. I also want to check if the solution formatting got fixed. It would help to inspect the diff after running `ruff` since it might have modified something. Additionally, `ruff` seemed to fix one error—maybe it was related to imports? Anyway, I’ll delete the scratch file.
assistant
`ruff` only complained about the scratch tuning script import layout, so I’m removing that scratch file from the final tree. The actual deliverable is `solution.py`.

**Considering pytest and GPU** I need to think about using pytest. I wonder if I should prioritize that over GPU-related tasks. It feels like testing might be mandatory, but I’m not sure if I need tests right now. Should I run `nvidia-smi` first? It doesn't seem necessary, but running it could be helpful to check the GPU status. I'm basically weighing the importance of these steps before I proceed.

**Investigating Git Status** Hmm, it looks like running `git status` shows nothing. I wonder if `solution.py` is untracked? Maybe it wasn't detected. It could be that the directory itself isn’t tracked properly? I’ll check by running `git status --short` from the current working directory. It seems like there's no output because `solution.py` might be ignored, but the file definitely exists. Alright, next step is to run `pytest` to see if everything works.

Lint is clean, and the GPU is idle before the last test command. I’m running `uv run pytest` now as required by the project instructions.

`uv run pytest` from the problem directory collected zero tests and returned pytest’s “no tests collected” exit code. I’m checking whether the repo has a broader test suite to run from the root; if not, I’ll report that exact pytest result and rely on `check.py` for problem correctness.

**Running tests in repo** I need to run pytest from the root of the repository, and it looks like there's probably no GPU available for this. A good plan is to utilize the command "uv run pytest" right from the repo's root directory. That should help me execute the tests effectively! I'll make sure I'm following the correct procedures to get everything done smoothly.

There is a root-level `tests/test_eval.py`, so I’m running pytest from the repository root instead of the problem leaf.

The root `uv run pytest` fails during collection from unrelated historical scratch files under `outputs/runs/...`, before reaching the real repo tests. I’m leaving those existing artifacts alone and running the checked-in `tests/` suite directly to verify the project tests themselves.

**Considering code inspection** I might need to run a `git diff` or check the status of my files. It seems important to inspect the `solution.py` file, especially after running `ruff`—that could help me ensure everything is functioning as expected. I'll make sure to keep an eye on any changes since the last commit, and double-check those adjustments for any potential errors. Let's get things sorted out!

**Considering grid implementation** I’m exploring the implementation of a grid with parameters like `max_rows_upper`, which could be set with expressions like `ceil_div(max_rows_upper, block_m)`. I wonder if setting `max_rows_upper` to a combination of values or a fixed number—like 4096—would work, considering potential skew. The benchmarking aspect makes it tricky since average values are known, but it seems setting `max_rows` to a generic value for all shapes complicates things significantly. It feels like the current approach might not be the best. **Considering file management** I’m contemplating whether to remove the `__pycache__` directory. It’s ignored, and while I could use `rm -rf __pycache__`, I’m realizing that it might not be necessary. Using `exec` could be destructive, and it’s not part of the source, so maybe I can keep it for clarity. Git status shows that it's ignored anyway, so it’s not a concern. I’m also wondering about `framework.txt`, which is generated but may still be useful to keep.

Implemented the custom Triton grouped GEMM + fused SwiGLU path in [solution.py](/home/infatoshi/cuda/KernelBench-Hard/problems/06_sonic_moe_swiglu/solution.py). The kernel launches one tile per `(expert, M tile, I tile)`, reads `expert_offsets` for the expert slice, accumulates both gate and up projections in fp32 from bf16 inputs, applies `silu(gate) * up` in the epilogue, and stores bf16. I tuned the tile choices for the required shapes: - Small shape uses `BLOCK_M=64, BLOCK_N=128, BLOCK_K=32`, `4` warps, `3` stages. - Larger 2048-row/expert shapes use `BLOCK_M=256, BLOCK_N=64, BLOCK_K=32`, `8` warps, `3` stages. - No forbidden ops are present in `solution.py`. **Verification** - `uv run check.py`: `PASS` - `uv run benchmark.py`: `RESULT: OK` - shape 0 solution: `41.216 TFLOPS`, `20.008 ms`, peak fraction `0.2061` - shape 1 solution: `75.308 TFLOPS`, `0.456 ms`, peak fraction `0.3765` - shape 2 solution: `40.826 TFLOPS`, `13.466 ms`, peak fraction `0.2041` - geomean `peak_fraction: 0.2511` - `uv run ruff check . --fix`: passed - `uv run pytest tests` from repo root: `10 passed` One caveat: plain `uv run pytest` is not a clean signal in this repo right now. From the problem directory it collects zero tests and exits with pytest code 5; from the repo root it tries to collect unrelated historical scratch tests under `outputs/runs/...` and fails during collection before reaching the checked-in test suite. The checked-in `tests/` suite passes.
