New Features

ifx is now fully compliant with Fortran 2018.

New Features

  • Fortran 2023 permits PRIVATE variables in PUBLIC NAMELIST groups.

  • Fortran 2023 requires INTEGER arguments to the SYSTEM_CLOCK intrinsic function to all be of at least default kind, and all integer arguments must have the same kind. These restrictions are diagnosed if the compiler is compiling for Fortran 2023 compliance (stand f23).

New OpenMP* Features

  • The INTERCHANGE loop transformation directive reorders the loops in a loop nest.

  • The OpenMP 6.0 WORKDISTRIBUTE construct divides the associated block of statements into units of work that are each executed once by a thread of the enclosing TEAMS construct.
