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).
