Thus, accessing the elements of column-wise is most efficient. That is to say, when stored in memory as a linear array, the matrix will be arranged as. Array storage in Fortran is column-major.Note: It is generally accepted that the intel compiler generates faster code on Intel hardware than gcc, although gcc is generally more compatible with a wide range of hardware. Print *,'Hello from thread number',OMP_GET_THREAD_NUM() Print *, total, ' greater or equal than average' There is direct support for openMP and openMPI.Ĭharacter(len=80) :: message ! a string of 80 characters Intel's Fortran compiler (ifort) is also compliant with Fortran back to F77 and earlier to most implementations. In addition, a significant number of Fortran 2003 and Fortran 2008 features are implemented.
The GFortran compiler is fully compliant with the Fortran 95 Standard and includes legacy F77 support. Fortran (formerly FORTRAN, derived from Formula Translation) is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
