Mathematical Acceleration Subsystem (MASS) Libraries for Linux - Version 4.4
Downloadable files
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
The MASS libraries are packaged as a compressed tar file, MASS_4.4_OS.tar.gz, where OS represents the Linux distribution and version number (e.g. RHEL5 or SLES10).
Version 4.4
- Adds new vector libraries libmassvp6.a and libmassvp6_64.a that contain the full set of 60 MASS vector routines tuned for POWER6: vacos, vacosh, vasin, vasinh, vatan2, vatanh, vcbrt, vcos, vcosh, vcosisin, vdint, vdiv, vdnint, vexp, vexpm1, vlog, vlog10, vlog1p, vpopcnt4, vpopcnt8, vpow, vqdrt, vrcbrt, vrec, vrqdrt, vrsqrt, vsin, vsincos, vsinh, vsqrt, vtan, vtanh, vsacos, vsacosh, vsasin, vsasinh, vsatan2, vsatanh, vscbrt, vscos, vscosh, vscosisin, vsdiv, vsexp, vsexpm1, vslog, vslog10, vslog1p, vspow, vsqdrt, vsrcbrt, vsrec, vsrqdrt, vsrsqrt, vssin, vssincos, vssinh, vssqrt, vstan, vstanh.
- Adds 15 new double-precision scalar routines to libmass.a and libmass_64.a: acos, acosh, anint, asin, asinh, atanh, cbrt, copysign, cosisin, erf, erfc, hypot, lgamma, log10, sincos.
- Contains various bug fixes.
Prerequisites
Note: If you are using any of the following products, be aware that a fully-supported version of the MASS libraries is shipped with the product, while any MASS libraries obtained from this download are not officially supported.
* IBM XL C/C++ Enterprise Edition for Linux, V7.0 or higher
* IBM XL C Enterprise Edition for Linux, V7.0 or higher
* IBM XL Fortran Enterprise for Linux, V9.1 or higher
Installation Instructions
The MASS libraries are packaged as a compressed tar file, MASS_4.4_OS.tar.gz, where OS represents the Linux distribution and version number (RHEL5 or SLES10).
The .tar package contains the following files:
* libmass.a - 32-bit MASS scalar library for general use.
* libmass_64.a - 64-bit MASS scalar library for general use.
* LICENSE - MASS license.
* libmassvp4.a - 32-bit MASS vector library with functions tuned for the POWER4+ architecture.
* libmassvp4_64.a - 64-bit MASS vector library with functions tuned for the POWER4+ architecture.
* libmassvp4gp.a - 32-bit MASS vector library with functions tuned for the POWER4 (GP) architecture.
* libmassvp4gp_64.a - 64-bit MASS vector library with functions tuned for the POWER4 (GP) architecture.
* libmassvp5.a - 32-bit MASS vector library with functions tuned for the POWER5 architecture.
* libmassvp5_64.a - 64-bit MASS vector library with functions tuned for the POWER5 architecture.
* libmassvp6.a - 32-bit MASS vector library with functions tuned for the POWER6 architecture.
* libmassvp6_64.a - 64-bit MASS vector library with functions tuned for the POWER6 architecture.
* 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 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.
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 directory mass/N/OS/ with subdirectories lib, lib64, include, and src, in the current directory, where N is the MASS version number and OS is the Linux distribution and version number.
To download and install the MASS libraries:
1. Download the correct tar ball based on your Linux distribution and version number.
2. Place the tar ball 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 ball:
tar -xzvf MASS_N_OS.tar.gz
where OS represents the Linux distribution and version number.
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):
