ArmPL

ArmPL, short for Arm Performance Libraries, is a suite of high-performance numerical routines developed by Arm for Arm-based processors. It provides optimized implementations of standard numerical libraries, including BLAS (Basic Linear Algebra Subprograms), LAPACK (Linear Algebra Package), and FFT (fast Fourier transforms), along with related routines for linear algebra, random number generation, and signal processing. The library is designed to exploit Arm-specific features such as NEON SIMD and, on newer cores, SVE, and to scale across multi-core hardware through threading frameworks like OpenMP.

ArmPL aims to deliver portable performance for scientific computing, engineering simulations, and data analytics on Arm-based servers and high-performance computing systems. It offers interfaces compatible with the Netlib BLAS/LAPACK standards, enabling straightforward porting of existing code. It supports integration with standard compilers and development toolchains used on Arm Linux systems.

Licensing for ArmPL is commercial, provided by Arm through its developer programs and partner ecosystems. It is distinct from Arm Compute Library, which focuses on GPU- and accelerator-optimized routines for computer vision and deep learning workloads.

Platform support centers on Linux-based Arm platforms, particularly 64-bit Arm servers (AArch64). The feature set and optimizations are tuned for modern Arm cores, and ArmPL is designed to complement other Arm software ecosystems for performance-critical applications.

In summary, ArmPL serves as Arm’s optimized, vendor-supported collection of classical numerical routines aimed at accelerating linear algebra, FFTs, and related computations on Arm-based hardware, with Netlib-compatible interfaces and commercial licensing.
