Mathematical Acceleration Subsystem (MASS) Libraries for Blue Gene/L - v. 4.2

 Downloadable files
 
Abstract
The MASS libraries consist of a set of mathematical functions for C, C++, and Fortran-language applications that are tuned for the Blue Gene/L architecture.
 
Download Description
The MASS libraries for Blue Gene/L are preliminary versions provided as a convenience to users, and have not yet been tested as thoroughly as the MASS libraries for other platforms.

The MASS libraries are packaged as a compressed tar file,  MASS_4.2_bgl.tar.gz
 The .tar package contains the following files:
* libmass.a - 32-bit MASS scalar library.
* LICENSE - MASS license.
* libmassvbgl.a - 32-bit MASS vector library.
* 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.
* massv.include - Header file containing the Fortran interface blocks for the vector functions.
* massv.h - Header file containing C/C++ prototypes for the vector functions.

Installation Instructions
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. 
The tar file creates the subdirectory, mass/4.2/bgl/lib/, in the current directory. 
1. Place the tar ball in a temporary directory (e.g. /tmp).

2. 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 to some system directories, such as /usr/local)
cd /home/userA/

3. Uncompress and untar the tar ball:
tar -xzvf MASS_4.2_bgl.tar.gz 

4. 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/4.2/bgl/lib/libmass.a  usr/lib/libmass.a
ln -s /home/userA/mass/4.2/bgl/lib/libmassvbgl.a  /usr/lib/libmassvbgl.a
