Mathematical Acceleration Subsystem (MASS) libraries for Blue Gene previous vers

Version 4.2

- Contains 32-bit scalar and vector libraries libmass.a and libmassvbgl.a, respectively, tuned for Blue Gene/L. Scalar functions: atan, atan2, cos, cosh, dnint, exp, log, pow, rsqrt, sin, sinh, sqrt, tan, tanh. Vector functions: vacos, vasin, vatan2, vcbrt, vcosh, vcosisin, vcos, vdint, vdiv, vdnint, vexpm1, vexp, vlog10, vlog1p, vlog, vpow, vrcbrt, vrec, vrsqrt, vsin, vsinh, vsqrt, vtanh, vtan, vsacos, vsasin, vsatan2, vscbrt, vscosh, vscosisin, vscos, vsdiv, vsexpm1, vsexp, vslog10, vslog1p, vslog, vspow, vsrcbrt, vsrec, vsrsqrt, vssin, vssinh, vssqrt, vstanh, vstan.

- Preliminary version provided as a convenience to users, has not been tested as thoroughly as the MASS libraries for other platforms.

Version 4.3

- Renamed the vector library to libmassv.a.
- Added new functions cosisin, sincos, vacosh, vasinh, vatanh, vrqdrt, vsacosh, vsasinh, vsatanh, vsrqdrt.
- Improved the performance of many functions.

libmass.a - 32-bit MASS scalar library.

libmassvbgl.a - 32-bit MASS vector library (v4.2).
libmassv.a - 32-bit MASS vector library (v4.3 and up).
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.

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/N/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_N_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/N/bgl/lib/libmass.a  /usr/lib/libmass.a
ln -s /home/userA/mass/N/bgl/lib/libmassv.a  /usr/lib/libmassv.a
(For v4.2, replace libmassv.a with libmassvbgl.a in the above.)
