-Docs
+Experimental machine learning framework featuring a graph-based JIT compiler.
-
+## Features
-Constensor is an ML framework which provides the following key features:
-
-- **Compile time shape, dtype, and device checking**: Develop quickly and handle common errors
-- **Opt-in half precision support**: Run on any GPU
-- **Advanced AI compiler features:**
+- Compile-time shape, dtype, and device checking
+- Opt-in half-precision (`f16`) and bfloat16 (`bf16`) support
+- Advanced AI compiler optimizations:
- Elementwise JIT kernel fusion
- - Automatic inplacing
+ - Automatic inlining and in-placing
- Constant folding
- - Dead code removal
+ - Dead code elimination
+- Multi-device support (CPU, optional CUDA)
+- Graph visualization (requires Graphviz)
+- Zero-cost abstractions with idiomatic Rust API
+
+## Installation
+
+Add `constensor-core` to your `Cargo.toml`:
+
+```toml
+[dependencies]
+constensor-core = "0.1.1"
+```
+
+To enable optional features (CUDA, half-precision, bfloat16):
+
+```toml
+[dependencies.constensor-core]
+version = "0.1.1"
+features = ["cuda", "half", "bfloat"]
+```
+
+Or using `cargo add`:
+
+```bash
+cargo add constensor-core
+```
-You can find out more with the [DeepWiki page](https://deepwiki.com/EricLBuehler/constensor)!
+## Quick Start
```rust
use constensor_core::{Cpu, Graph, GraphTensor, Tensor, R2};
fn main() {
+ // Create an empty computation graph
let mut graph: Graph = Graph::empty();
- let x: GraphTensor, f32, Cpu> =
- GraphTensor::, f32, Cpu>::fill(graph.clone(), 1.0);
- let y: GraphTensor, f32, Cpu> =
- GraphTensor::, f32, Cpu>::fill(graph.clone(), 2.0);
- let z: GraphTensor, f32, Cpu> = y.clone() + y * x;
+ // Define graph tensors
+ let x = GraphTensor::, f32, Cpu>::fill(&mut graph, 1.0);
+ let y = GraphTensor::, f32, Cpu>::fill(&mut graph, 2.0);
+
+ // Build computation
+ let z = y.clone() + y * x;
+
+ // Optimize the graph
graph.optimize();
+ // Visualize the optimized graph (requires Graphviz)
graph.visualize("graph.png").unwrap();
+ // Execute and retrieve the result
let tensor: Tensor, f32, Cpu> = z.to_tensor().unwrap();
-
- assert_eq!(tensor.data().unwrap().to_vec(), vec![vec![4.0; 4]; 3],);
+ assert_eq!(tensor.data().unwrap().to_vec(), vec![vec![4.0; 4]; 3]);
}
+```
+
+## Examples
+Run the provided examples:
+
+```bash
+cargo run --example hello_world --features half
+cargo run --example matmul --features cuda,bfloat
```
-## Opt-in half precision support
-Via the following feature flags:
-- `half` for f16
-- `bfloat` for bf16
\ No newline at end of file
+See more examples in [`constensor-core/examples`](constensor-core/examples).
+
+## Documentation
+
+API documentation is available on [docs.rs](https://docs.rs/constensor-core).
+
+## More Info
+
+- DeepWiki: https://deepwiki.com/EricLBuehler/constensor
+
+## Contributing
+
+Contributions are welcome! Please open issues and submit pull requests.
+
+- Run tests with all features:
+
+ ```bash
+ cargo test --workspace --features "cuda half bfloat"
+ ```
+
+- Format code: `cargo fmt --all`
+- Lint code: `cargo clippy --all-targets -- -D warnings`
