Features and benefits
Mathematical Acceleration Subsystem (MASS) for Linux® consists of libraries of mathematical intrinsic functions tuned specifically for optimum performance on POWER architectures.
These libraries and functions:
Include both scalar and vector functions.
Are thread-safe.
Support both 32-bit and 64-bit compilations.
Offer improved performance over their corresponding standard system library routines.
Are intended for use in C, C++, and Fortran applications where slight differences in accuracy or handling of exceptional values can be tolerated.
Mathematical Acceleration Subsystem for Linux includes the libraries described below:
