{{Package-Introduction|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.|http://developer.amd.com/acml.jsp}}

{{Note|The ACML license does not allow redistribution without written consent from AMD.}}

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

== 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:

   ./install-<package>.sh

where <package> is acml-{{ACML-Version}}-gfortran-32bit, acml-{{ACML-Version}}-gfortran-64bit, acml-{{ACML-Version}}-gnu-32bit, or acml-{{ACML-Version}}-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/acml{{ACML-Version}}.  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-{{ACML-Version}} && 
    install -v -m644 ACML-EULA.txt README.64-bit /usr/share/doc/acml-{{ACML-Version}} && 
    mv -v /opt/acml{{ACML-Version}}/{*.txt,ReleaseNote*} /usr/share/doc/acml-{{ACML-Version}} && 
    mv -v /opt/acml{{ACML-Version}}/Doc/*.{pdf,txt,inf*} /usr/share/doc/acml-{{ACML-Version}} && 
    mv -v /opt/acml{{ACML-Version}}/Doc/html/* /usr/share/doc/acml-{{ACML-Version}}
