Link Time Optimization (LTO)

Enables you to take advantage of intermodular optimizations without making any significant changes to the makefiles or build system. You can deliver big improvements in both compile time and memory usage when utilizing LTO.

 Explore feature
Language standard compliance

Supports FORTRAN 77, Fortran 90, Fortran 95, Fortran 2003, a subset of Fortran 2008 and a subset of Technical Specification 29113 for further interoperability of Fortran with C. This helps to protect investments in existing Fortran source and object code.

 Explore standards
Vector intrinsic procedures

Manipulate vectors and its elements by using storage association, the TRANSFER intrinsic, or the Vector Multimedia Extension (VMX) and the Vector Scalar Extension (VSX) intrinsic functions.
