# KernelBot Competition Data

This dataset contains GPU kernel submissions from the KernelBot competition platform. Submissions are optimized GPU kernels written for specific hardware targets.

## Data Files

### AMD MI300 Submissions
| File | Description |
|------|-------------|
| `submissions.parquet` | All AMD competition submissions |
| `successful_submissions.parquet` | AMD submissions that passed correctness tests |
| `deduplicated_submissions.parquet` | AMD submissions deduplicated by (user, code) |
| `deduplicated_successful_submissions.parquet` | Deduplicated passing AMD submissions |

**AMD Problems:** fp8-gemm, moe (mixture of experts), mla-decode, all2all, gemm+reducescatter, allgather+gemm

### NVIDIA Blackwell NVFP4 Submissions
| File | Size | Description |
|------|------|-------------|
| `nvidia_nvfp4_submissions.parquet` | ~1.4 GB | NVFP4 submissions deduplicated by (user, code), with full code content |


**NVFP4 Problems:** gemv (leaderboard 595), gemm (597), dual_gemm (598), modal_dual_gemm (697)

**Note on Dual GEMM:** There are two variants of the dual_gemm problem. Midway through the competition, on-prem hardware measurements became unreliable, so a second leaderboard was created on Modal infrastructure. The Modal measurements (leaderboard 697, `modal_nvfp4_dual_gemm`) are more trustworthy.

**Note:** Scores are execution time in seconds. **Lower is better.**

## Helper Scripts

- `analyze_submissions.py` - Python functions for analyzing submissions
- `skills.md` - Documentation for data processing workflows

### Quick Start

```python
from analyze_submissions import load_submissions, top_contestants, author_progression

# Load NVIDIA NVFP4 data
df = load_submissions()

# Get top 20 for a problem
leaders = top_contestants(df, problem_name='nvfp4_gemm', n=20)

# See a user's progression over time
progression = author_progression(df, user_name='username', problem_name='nvfp4_gemm')
```
