Description and functionality provided

The ATLAS libraries contain all the Basic Linear Algebra Subprograms (BLAS) and a subset of the Linear Algebra Package (LAPACK) routines with interfaces provided for both C and Fortran F77 versions of the routines across platforms and architectures. Versions are provided and tuned herein for both the single-threaded and multi-threaded execution on IBM® zEC12/zBC12 and IBM z13 hardware models. C and C++ calling programs are supported, with 31-bit C linkage, 31-bit XPLINK linkage, or 64-bit linkage.

Note: ATLAS is only provided as a USS package.

If you want to call ATLAS functionality in your program, take the following steps:

Provide the prototype for the functions by including the appropriate header file (see Supplied ATLAS libraries and their corresponding header files for header file names).
Link with the appropriate ATLAS libraries (see Supplied ATLAS libraries and their corresponding header files for library names).
Use the appropriate compiler and linker flags (see Required compiler options).
