 library released by AMD. This library provides useful mathematical routines optimized for AMD processors.

Originally developed in 2002 for use in high-performance computing

High-performance computing

High-performance computing uses supercomputers and computer clusters to solve advanced computation problems. Today, computer systems approaching the teraflops-region are counted as HPC-computers.-Overview:...

 (HPC) and scientific computing, ACML allows nearly optimal use of AMD Opteron

Opteron

Opteron is AMD's x86 server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture . It was released on April 22, 2003 with the SledgeHammer core and was intended to compete in the server and workstation markets, particularly in the same...

Features

ACML consists of the following main components:

• A full implementation of Level 1, 2 and 3 Basic Linear Algebra Subprograms
  Basic Linear Algebra Subprograms
  Basic Linear Algebra Subprograms is a de facto application programming interface standard for publishing libraries to perform basic linear algebra operations such as vector and matrix multiplication. They were first published in 1979, and are used to build larger packages such as LAPACK...
  
   (BLAS), with optimizations for AMD Opteron processors.
• A full suite of Linear Algebra
  Linear algebra
  Linear algebra is a branch of mathematics that studies vector spaces, also called linear spaces, along with linear functions that input one vector and output another. Such functions are called linear maps and can be represented by matrices if a basis is given. Thus matrix theory is often...

  ) routines.
• A comprehensive suite of Fast Fourier transform
  Fast Fourier transform
  A fast Fourier transform is an efficient algorithm to compute the discrete Fourier transform and its inverse. "The FFT has been called the most important numerical algorithm of our lifetime ." There are many distinct FFT algorithms involving a wide range of mathematics, from simple...
  
   (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
