Program optimization
The XL Fortran compiler helps you control the optimization of your programs:
- You can select different levels of compiler optimizations.
- You can turn on separate optimizations for loops, floating point, and
other categories.
- You can optimize a program for a particular class of machines or for a
very specific machine configuration, depending on where the program will
run.
The XL Fortran Optimization and Programming Guide provides a road map and optimization
strategies for these features.
