422. Set up ACML on linux

These are the same instructions as in post 409B. However, I've decided it's better to do the posts the unix/linux way -- have the do one thing, and do that thing well. It makes life easier for me if I can simply refer back to more modular posts.

Anyway, here's how to set up the ACML libs on debian.

ACML
Download both the 'regular' and the int64 gfortran packages from AMD:
http://developer.amd.com/tools-and-sdks/cpu-development/amd-core-math-library-acml/acml-downloads-resources/#download

tar xvf acml-5-3-1-gfortran-64bit-int64.tgz
tar xvf acml-5-3-1-gfortran-64bit.tgz
sh install-acml-5-3-1-gfortran-64bit-int64.sh

Where do you want to install ACML?  Press return to use
the default location (/opt/acml5.3.1), or enter an alternative path.
The directory will be created if it does not already exist.
> /opt/acml/acml5.3.1

sh install-acml-5-3-1-gfortran-64bit.sh

Where do you want to install ACML?  Press return to use
the default location (/opt/acml5.3.1), or enter an alternative path.
The directory will be created if it does not already exist.
> /opt/acml/acml5.3.1

You'll get something like this:

/opt/acml/acml5.3.1
|-- Doc
|-- gfortran64
|-- gfortran64_fma4
|-- gfortran64_fma4_int64
|-- gfortran64_fma4_mp
|-- gfortran64_fma4_mp_int64
|-- gfortran64_int64
|-- gfortran64_mp
|-- gfortran64_mp_int64
`-- util

where
*  fma4 is for cpus with FMA4 support (use util/cpuid to check)
*  int64 is for double-precision float (integer*8) I think
*  mp is for openmp. For MPI do not use the _mp_ libraries!

Pick your library/ies and add them to the LD_LIBRARY_PATH, e.g.:

echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/acml/acml5.3.1/gfortran64_int64/lib' >> ~/.bashrc
source ~/.bashrc
