ArrayFire is a general-purpose tensor library that simplifies the software development process for the parallel architectures found in CPUs, GPUs, and other hardware acceleration devices. The library serves users in every technical computing market.
Several of ArrayFire's benefits include:
- Hundreds of accelerated tensor computing
functions, in the
following areas:
- Array handling
- Computer vision
- Image processing
- Linear algebra
- Machine learning
- Standard math
- Signal Processing
- Statistics
- Vector algorithms
- Easy to use, stable, well-documented API
- Rigorous benchmarks and tests ensuring top performance and numerical accuracy
- Cross-platform compatibility with support for CUDA, oneAPI, OpenCL, and native CPU on Windows, Mac, and Linux
- Built-in visualization functions through Forge
- Commercially friendly open-source licensing
- Enterprise support from ArrayFire
ArrayFire provides software developers with a high-level abstraction of data
that resides on the accelerator, the af::array object. Developers write code
that performs operations on ArrayFire arrays, which, in turn, are automatically
translated into near-optimal kernels that execute on the computational device.
ArrayFire runs on devices ranging from low-power mobile phones to high-power GPU-enabled supercomputers. ArrayFire runs on CPUs from all major vendors (Intel, AMD, ARM), GPUs from the prominent manufacturers (AMD, Intel, NVIDIA, and Qualcomm), as well as a variety of other accelerator devices on Windows, Mac, and Linux.
Instructions to install or to build ArrayFire from source can be found on the wiki.
