Mathematical Acceleration Subsystem (MASS) Libraries for Blue Gene/L - v. 4.4
Downloadable files
Abstract
The MASS libraries consist of a set of mathematical subroutines for C, C++, and Fortran-language applications that are tuned for the Blue Gene/L and Blue Gene/P architectures.
Download Description
Differences from v4.3:
Added libraries tuned for the Blue Gene/P architecture.
The MASS libraries are packaged as a compressed tar file, MASS_4.4_BGV.tar.gz, where BGV=bgl for Blue Gene/L, or BGV=bgp for Blue Gene/P.
The .tar package contains the following files:
LICENSE - MASS license.
libmass.a - 32-bit MASS scalar library.
libmassv.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.
mass.include - Header file containing the Fortran interface blocks for the scalar functions that are not Fortran intrinsic functions.
massv.include - Header file containing the Fortran interface blocks for the vector functions.
mass.h - Header file containing C/C++ prototypes for the scalar functions that are not in math.h.
massv.h - Header file containing C/C++ prototypes for the vector functions.
Prerequisites
none
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/4.4/BGV/lib/, in the current directory, where BGV=bgl for Blue Gene/L or BGV=bgp for Blue Gene/P.
Place the tar ball in a temporary directory (e.g. /tmp).
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/
Uncompress and untar the tar ball:
tar -xzvf MASS_4.4_BGV.tar.gz
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/4.4/BGV/lib/libmass.a usr/lib/libmass.a
ln -s /home/userA/mass/4.4/BGV/lib/libmassv.a /usr/lib/libmassv.a
