# High-performance libraries that are tuned for POWER9

Use the MASS vector library and SIMD library to exploit the POWER9 architecture.

- MASS libraries
- The vector library libmassvp9.a and the SIMD library libmass_simdp9.a contain functions that are tuned for the POWER9 architecture.
- For how to use MASS libraries, see Using the Mathematical Acceleration Subsystem (MASS) libraries.
