RunPod A100 SXM lab setup, Linux GPU validation, CUDA/NCCL benchmark methodology, evidence discipline, and executive-ready reporting.
Public release boundary: this repository documents engineering methodology, sanitized evidence references, benchmark interpretation, and executive reporting. GPUValidator is proprietary software. No source code, product internals, API contracts, database schemas, authentication/RBAC design, agent protocol, customer data, private URLs, secrets, or production screenshots are included.

GPU Benchmark Lab is a launch-candidate portfolio repository showing how an enterprise GPU validation environment was engineered, exercised, documented, and communicated without exposing proprietary platform implementation.
The repository demonstrates:
- Linux-based GPU infrastructure validation on a RunPod single-node, multi-GPU environment.
- NVIDIA A100 SXM hardware awareness and driver/runtime evidence capture.
- CUDA and NCCL version provenance from sanitized benchmark output.
- NCCL collective benchmark methodology with numeric claims limited to included evidence.
- Evidence-to-report translation for technical, customer, management, and interview audiences.
- Clear separation between public methodology and the private GPUValidator platform.
A public engineering case study for:
- Building a controlled GPU benchmark lab.
- Capturing safe evidence from a Linux GPU environment.
- Explaining CUDA/NCCL benchmark methodology.
- Turning technical evidence into customer and executive documentation.
- Demonstrating professional judgment around IP protection.
This repository is not GPUValidator source code, a production deployment guide, a customer certification, or a disclosure of proprietary implementation. It does not include private APIs, schemas, auth/RBAC design, agent protocols, message formats, secrets, private URLs, customer data, or production screenshots.

GPUValidator is mentioned only as proprietary software that supports GPU infrastructure validation workflows. This repository does not disclose how it is implemented.
| Benchmark | Public status | Why it matters |
|---|---|---|
| AllReduce | Sanitized fixture rows included | Gradient synchronization and replicated reduction |
| AllGather | Methodology only | Tensor/model-parallel materialization |
| ReduceScatter | Methodology only | Sharded optimizers and memory-efficient reduction |
| Broadcast | Methodology only | Root-to-rank parameter or configuration distribution |
| Reduce | Methodology only | Root-centric metric or loss aggregation |
| AllToAll | Methodology only | Expert-parallel token exchange and distributed transpose |
| SendRecv | Methodology only | Pipeline-parallel and custom point-to-point exchange |
No benchmark metrics are invented. Numeric rows appear only where the included fixture contains them, and the fixture limitations are stated.
