Lumina is a high-performance linear algebra framework written in Rust, optimized for machine learning workloads. This article explores its GPU acceleration capabilities and benchmark performance across multiple AI research applications.
Lumina combines Rust's memory safety with GPU acceleration through vulkan and CUDA backends. The framework supports both f32 and f16 precision modes, enabling efficient operations for both training and inference use cases.
Performance Benchmarks
Stress testing matrix operations across different device configurations:
Configuration | Matrix Size | Throughput |
---|---|---|
CPU (AVX2) | 1000x1000 | 428 MFLOPs |
GPU (RTx 4090) | 4096x4096 | 3.1 TFLOPs |
Hybrid (CPU+GPU) | 8192x8192 | 5.8 TFLOPs |
Core Features
- • Safe, type-checked tensor operations with compile-time shape verification
- • 2.4x speed improvement over numpy for large matrix calculations
- • Automatic GPU memory pooling across vulkan/CUDA devices
- • Python interoperability via PyO3 bindings
Code Example
Basic tensor operations in Lumina:
#[derive(Debug)]
struct Tensor {
data: Vec,
shape: Vec,
}
impl + Copy> Tensor {
fn add(&self, other: &Self) -> Self {
assert_eq!(self.shape, other.shape);
Tensor {
data: self.data.iter()
.zip(other.data.iter())
.map(|(a, b)| *a + *b)
.collect(),
shape: self.shape.clone(),
}
}
}
"Lumina's design demonstrates how Rust's ownership model enables safe, high-performance tensor operations. The strict compile-time verification of dimension compatibility helps prevent entire classes of runtime errors common in other numerical frameworks."
