Download Source: (to download one or more tarball acml-3.6.1-gfortran-32bit, acml-3.6.1-gfortran-64bit, acml-3.6.1-gnu-32bit, or acml-3.6.1-gnu-64bit)

Introduction to ACML

AMD Core Mathematics Library (ACML) contains

  • Full implementation of ATLAS, with key routines optimized for high performance on AMD processors.
  • Full suite of LAPACK routines optimized to achieve considerably higher performance than standard LAPACK implementations.
  • Comprehensive suite of Fast Fourier Transforms (FFTs) in both single-, double-, single-complex and double-complex data types.
  • Fast scalar, vector, and array math transcendental library routines optimized for high performance on AMD processors.
  • Random Number Generators in both single- and double-precision.

To obtain the ACML, you will be required to register with AMD and be at least 14-years old. The packages compiled with gfortran provide libraries optimized for single- and multi-processor machines.

The ACML license does not allow redistribution without written consent from AMD.

Other vendors also provide ATLAS and LAPACK libraries optimized for their processor.

Apple's Velocity Engine
Hewlett-Packard's Mathematical Software Library (MLIB) Free registration required.
IBM's Engineering Scientific Subroutine Library (ESSL)
Intel's Math Kernel Library (MKL) $399 US.
SGI's Scientific Computing Software Library (SCSL) Free registration required.
Sun's Sun Performance Library; Free to registered SDN members.

Non-Multilib or Multilib

Create a directory to download and unpack the tarballs.

  mkdir acml &&
  cd acml

After retrieving and unpacking the tarballs, install each in turn:


where <package> is acml-3.6.1-gfortran-32bit, acml-3.6.1-gfortran-64bit, acml-3.6.1-gnu-32bit, or acml-3.6.1-gnu-64bit.

You will be required to accept the licensing agreement after which you will be prompted for a top level installation directory. The default is /opt/acml3.6.1. Each package will install its headers and libraries in separate subdirectories of the top level directory.

Move the documentation to a standard location:

   install -v -m755 -d /usr/share/doc/acml-3.6.1 && 
   install -v -m644 ACML-EULA.txt README.64-bit /usr/share/doc/acml-3.6.1 && 
   mv -v /opt/acml3.6.1/{*.txt,ReleaseNote*} /usr/share/doc/acml-3.6.1 && 
   mv -v /opt/acml3.6.1/Doc/*.{pdf,txt,inf*} /usr/share/doc/acml-3.6.1 && 
   mv -v /opt/acml3.6.1/Doc/html/* /usr/share/doc/acml-3.6.1


Installed Directories: /opt/acml3.6.1/{gfortran32,gfortran32_mp,gfortran64,gfortran64_mp,gnu32,gnu64}/{examples,include,lib}
Installed Programs: cpuid

Short Descriptions

cpuid: binary utility to determine if your processor supports sse and sse2. Execute cat /proc/cpuinfo for the same results.
