## Project Overview
clpeak is an open-source project written in C++: Peak compute, memory bandwidth and latency of CPUs, GPUs and NPUs: the same tests through every API that reaches a device. Command line and app for Windows, macOS, Linux and Android.

Engineered for speed, consistency, and developer ease, it solves common hurdles in benchmark, coreml, cpu. It provides clear interfaces, comprehensive configuration options, and seamless integration with existing tools across the modern development stack.

## Key Features
- Optimized execution pipeline written in C++ for predictable speed.
- Zero-friction configuration with comprehensive sensible defaults out of the box.
- Cross-platform runtime support across Linux, macOS, and Windows environments.
- Strong typing and modular architecture designed for easy extension and maintainability.
- Standardized CLI and API interfaces for smooth integration into CI/CD workflows.
- Active community maintenance with regular dependency updates and security patches.

## Installation & Quick Start
### Linux
```bash
git clone https://github.com/krrishnarraj/clpeak.git
cd clpeak
```

### macOS
```bash
git clone https://github.com/krrishnarraj/clpeak.git
cd clpeak
```

### Windows
```bash
git clone https://github.com/krrishnarraj/clpeak.git
cd clpeak
```

## System Requirements & Architecture
- **Supported Platforms**: macOS, Linux, Windows
- **Runtime Dependencies**: C++20 compliant compiler (GCC 11+, Clang 13+, MSVC)
- **Architecture**: x86_64, ARM64 (Apple Silicon & Graviton)

## How It Works
clpeak coordinates its core functionality through a modular C++ pipeline. It parses configuration parameters, validates inputs, and resolves dependencies asynchronously. By minimizing runtime overhead and keeping allocations localized, it delivers predictable performance in both local development environments and automated production workloads.

## Production Use Cases
### Production System Integration
Embed clpeak into C++ backend services to handle core application logic.

### CI/CD Automated Pipelines
Run automated validation, builds, and integration suites during deployments.

### Developer Tooling & Workflows
Accelerate developer onboarding with pre-configured project utilities.

### Open Source Extension
Fork and customize internal modules under the repository's open GPL-3.0 license.

## Target Audience
Developers and engineering teams building with C++, seeking reliable, tested, and actively maintained tooling for production workloads.

## Strengths
- Active community backing with 527 GitHub stars and verified adoption.
- Permissive open-source distribution under the GPL-3.0 license.
- Built in C++ for high execution speed and developer familiarity.
- Cross-platform compatibility across modern Linux, macOS, and Windows environments.
- Clean modular design allowing flexible configuration and pipeline integration.

## Considerations
- Requires familiarity with C++ and modern CLI workflows.
- Ecosystem extensions may require manual configuration depending on environment constraints.
- Active development roadmap means breaking API changes may occur across major versions.
