Appendix C. Using the Mathematical Acceleration Subsystem (MASS)

XL Fortran Advanced Edition V9.1 for Linux ships the Mathematical Acceleration Subsystem (MASS), a set of libraries of tuned mathematical intrinsic functions that provide improved performance over the corresponding standard math library functions. The accuracy and exception handling might not be identical in MASS functions and standard math library functions.

The MASS libraries on Linux consist of a library of vector functions, described in Using the Vector Libraries. Compiling and Linking a Program with MASS describes how to compile and link a program that uses the MASS libraries. IBM Copyright 2003
