Using the high performance libraries
XL C/C++ Advanced Edition for Linux 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).
- The Basic Linear Algebra Subprograms (BLAS) are a set of
routines which provide matrix/vector multiplication functions tuned for PowerPC
architectures. The BLAS functions are described in Using the Basic Linear Algebra Subprograms (BLAS).
