Abstract

The MASS libraries consist of a set of mathematical functions for C, C++, and Fortran-language applications that are tuned for specific POWER architectures.

Download Description

Prerequisites

Note: If you are using any of the following products, be aware that a fully-supported version of the MASS libraries for Linux (big endian) is shipped with the product, while any MASS libraries obtained from this download are not officially supported.

* IBM XL C/C++ for Linux, V7.0 or higher
* IBM XL C for Linux, V7.0 or higher
* IBM XL Fortran for Linux, V9.1 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.

Installation Instructions

The MASS libraries for Linux (Big Endian) are packaged as a compressed tar file, MASS_8.1.0_linux_BE.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/8.1.0/linux_BE with subdirectories LICENSE, lib, include, and src. These directories contain the following files:

* LICENSE/
* The MASS license documents.

* lib/
* libmass.a - 32-bit MASS scalar library for general use.

* libmassv.f - Fortran source file of simple loops for the MASS vector functions, for use on non-IBM machines.
* libmassv.c - C/C++ source file of simple loops for the MASS vector functions, for use on non-IBM machines.

* 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_simd.include - Header file containing the Fortran interface blocks for the SIMD functions.
* mass_simdp7.include - Deprecated version of mass_simd.include.

* mass_simd.h - Header file containing C/C++ prototypes for the SIMD functions.
* mass_simdp7.h - Deprecated version of mass_simd.h.

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_8.1.0_linux_BE.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/8.1.0/linux_BE/lib/* /usr/lib/
