Using the high performance libraries

IBM® XL C for AIX®, V13.1.3 is shipped with a set of libraries for high-performance mathematical computing:

• The Mathematical Acceleration Subsystem (MASS) is a set of libraries of tuned mathematical intrinsic functions that provide improved performance over the corresponding standard system math library functions. MASS is described in Using the Mathematical Acceleration Subsystem (MASS) libraries.
• The Basic Linear Algebra Subprograms (BLAS) are a set of routines that provide matrix/vector multiplication functions tuned for PowerPC® architectures. The BLAS functions are described in Using the Basic Linear Algebra Subprograms – BLAS.
