IBM® XL C/C++ for Linux®,
V11.1 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 libraries (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.
