Fastor
A lightweight, header-only C++ tensor algebra framework delivering bare-metal performance for small matrix/tensor operations via compile-time optimizations.
What is Fastor?
Fastor is a lightweight, high-performance tensor algebra framework for modern C++. It provides a high-level interface for manipulating multi-dimensional arrays while delivering bare-metal performance for small matrix/tensor operations through compile-time optimizations and explicit SIMD vectorization. It solves the problem of achieving vendor-library performance in C++ without heavy dependencies or runtime overhead.
Scientific programmers, computational engineers, and developers working on performance-critical numerical applications in C++, especially those in fields like computational mechanics, physics simulations, and embedded systems.
Developers choose Fastor for its unique combination of a high-level, intuitive API with compile-time operation minimization and SIMD optimization, resulting in performance rivaling specialized libraries like MKL JIT, all in a lightweight, header-only package with zero dynamic allocations.
