Power10 technology exploitation
IBM® Open XL Fortran for AIX® 17.1.2 provides the exploitation of the Power10 technology. The Power10 exploitation features include compiler options, high-performance libraries, and intrinsic procedures.
Compiler options
- -qarch=pwr10
- Produces code that exploits the features of the Power10 processor. Programs built with this option can only run on a Power10 processor or simulator.
- -qtune=pwr10
- Optimizations are tuned for the Power10 hardware platform.
MASS libraries
The vector library libmassvp10.a and the SIMD library libmass_simdp10.a contain functions that are tuned for the Power10 architecture.
The generic vector library libmassv.a and the generic SIMD library libmass_simd.a that run on any supported Power® processor are also provided. They provide balanced performance tuning across the range of processors while favoring Power9 and Power10. Unless your application requires this portability, use the appropriate architecture-specific vector or SIMD libraries for maximum performance.
