A general-purpose tensor library for parallel computing across CPUs, GPUs, and hardware accelerators.
ArrayFire is a general-purpose tensor library that simplifies parallel computing across CPUs, GPUs, and other hardware accelerators. It provides a high-level abstraction via `af::array` objects, automatically optimizing operations for performance while maintaining cross-platform compatibility. The library addresses the complexity of writing efficient, portable code for diverse parallel architectures.
Developers and researchers in scientific computing, machine learning, computer vision, and signal processing who need high-performance tensor operations across multiple hardware platforms. It's particularly valuable for those seeking to write portable code without deep expertise in low-level GPU or accelerator programming.
ArrayFire offers a unified, easy-to-use API that abstracts hardware details, enabling developers to write once and run efficiently everywhere—from mobile phones to supercomputers. Its rigorous performance tuning, extensive function library, and cross-platform support make it a robust choice for accelerating technical computing workloads.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports CUDA, oneAPI, OpenCL, and native CPU backends on Windows, Mac, and Linux, enabling code to run on diverse hardware without changes, as highlighted in the cross-platform compatibility section.
The `af::array` object automatically translates operations into near-optimal kernels for the target device, simplifying parallel programming without deep hardware expertise, as described in the high-level abstraction philosophy.
Offers hundreds of accelerated functions for linear algebra, machine learning, signal processing, and more, covering key technical computing domains listed in the tensor computing functions.
Integrated Forge library provides visualization functions, allowing direct plotting of results within GPU-accelerated workflows, mentioned in the built-in visualization benefits.
Has fewer pre-built models and tools compared to frameworks like PyTorch, and many language wrappers are community-maintained or in-progress, limiting out-of-the-box functionality and integration.
While optimized, the high-level API may not achieve peak performance for highly specialized, edge-case computations compared to hand-tuned, hardware-specific code, as it generalizes across devices.
Several language APIs are listed as in-progress, such as .NET and Java, which can hinder adoption in those ecosystems until fully supported and documented.
