Mathematical Acceleration Subsystem

Libraries of high-performance mathematical functions

IBM® Mathematical Acceleration Subsystem (MASS) consists of libraries of mathematical functions tuned for optimum performance on a variety of IBM processors.

Mathematical Acceleration Subsystem (MASS) consists of libraries of tuned mathematical functions, available in versions for the AIX® and Linux® platforms.
MASS libraries offer improved performance over the standard mathematical library routines, are thread-safe and support compilations in C, C++, and Fortran applications.
The MASS libraries are shipped with the XL C, XL C/C++, and XL Fortran compiler products, and are also available for separate download from this site.
