HELLO is a FORTRAN90 program which says "Hello, world!".
If you're just trying to learn FORTRAN90, or learning how to use FORTRAN90 on a different computer system, or in batch mode, it's helpful if you start with a very simple program with a tiny amount of output that should print immediately if things are working well.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
HELLO is available in a C version and a C++ version and a FORTRAN77 version and a FORTRAN90 version and a Java version and a MATLAB version and an R version.
HELLO_MPI, a FORTRAN90 program which prints out "Hello, world!" using the MPI parallel programming environment.
HELLO_OPENMP, a FORTRAN90 program which prints out "Hello, world!" using the OpenMP parallel programming environment.
HELLO_MOAB runs the program on the FSU HPC system. The script is submitted from a directory which contains the source code.
