Prerequisites
Note: If you are using any of the following compilers, be aware that a fully-supported version of the MASS libraries for Linux (little endian) is shipped with the compiler, while any MASS libraries obtained from this download are not officially supported.
* IBM XL C/C++ for Linux, V13.1 or higher
* IBM XL Fortran for Linux, V15.1 or higher
We recommend using MASS with the IBM XL compilers, since they provide optimizations closely-coupled to MASS for ease of use and enhanced performance.
* IBM XL C/C++ for Linux, V13.1 or higher
* IBM XL Fortran for Linux, V15.1 or higher

Installation Instructions
The MASS libraries for Linux (Little Endian) are packaged as a compressed tar file, MASS_8.1.3_linux_LE.tar.gz. The license documents are included in the tar package, and are also provided for separate download.
The tar file creates the directory mass/8.1.3/linux_LE with subdirectories LICENSE, lib, include, and src. These directories contain the following files:
* LICENSE/
The MASS license documents.
* lib/
libmass.a - 64-bit MASS scalar library with functions tuned for the POWER8 processor.
libmassvp8.a - 64-bit MASS vector library with functions tuned for the POWER8 processor.
libmassv.a - A link to libmassvp8.a.
libmass_simdp8.a - 64-bit MASS SIMD library with functions tuned for the POWER8 processor.
* include/
mass.include - Header file containing the Fortran interface block for scalar functions that are not Fortran intrinsics.
massv.include - Header file containing the Fortran interface blocks for the vector functions.
mass.h - Header file containing the C/C++ prototype for scalar functions not in math.h.
massv.h - Header file containing C/C++ prototypes for the vector functions.
* src/
libmassv.f - Fortran source file of simple loops for the MASS vector functions, for portability on non-IBM processors.
libmassv.c - C/C++ source file of simple loops for the MASS vector functions, for portability on non-IBM processors.
The MASS libraries are more convenient to use when they are installed with root access and linked to the conventional /usr/lib/ directory because the user can specify the shorthand -lmass flags during compilation, instead of specifying an explicit path for the libraries.
To download and install the MASS libraries:
1. Download the tar file.
2. Place the tar file in a temporary directory (e.g. /tmp).
3. Go to the directory where you would like the MASS libraries to exist on the system (e.g. /home/userA/):
(You will need root authority if you try to place the MASS libraries in some system directories, such as /usr/local)
cd /home/userA/
4. Uncompress and untar the tar file:
tar -xzvf MASS_8.1.3_linux_LE.tar.gz
5. If you need to link without using the -L path at compile time, you will need to create symbolic links as follows (you require
root authority in this step):
ln -s /home/userA/mass/8.1.3/linux_LE/lib/* /usr/lib/
The tar file creates the directory mass/8.1.3/linux_LE with subdirectories LICENSE, lib, include, and src. These directories contain the following files:
