AMD Core Math Library

AMD Core Math Library (ACML) is an end-of-life^[1] software development library released by AMD, replaced by many open source libraries, including AMD libm 4.0. This library provides mathematical routines optimized for AMD processors.

The successor to ACML is the AMD Optimizing CPU Libraries (AOCL), a set of mostly open source libraries compiled for AMD64 processors. It includes the open source BLIS, libFLAME, ScaLAPACK, FFTW, and AOCL-Sparse, plus the original closed-source AMD LibM, memcpy, and RNG.^[2]

ACML consists of the following main components:^[3]

• A full implementation of Level 1, 2 and 3 Basic Linear Algebra Subprograms (BLAS), with optimizations for AMD Opteron processors.
• A full suite of Linear Algebra (LAPACK) routines.
• A comprehensive suite of Fast Fourier transform (FFTs) in single-, double-, single-complex and double-complex data types.
• Fast scalar, vector, and array math transcendental library routines
• Random Number Generators in both single- and double-precision

AMD offers pre-compiled binaries for Linux, Solaris, and Windows available for download. Supported compilers include GNU Fortran, Intel Fortran Compiler, Microsoft Visual Studio, NAG, PathScale, PGI compiler, and Sun Studio.^[4]

ACML has a proprietary freeware license. The library is distributed in binary form free of charge, but cannot be freely redistributed.^[5][6]
