The following is a list of C, C++ and Fortran compilers available on the SUN cluster and the M9000:

• cc
• CC
• f90/f95

• gcc
• g++
• gfortran

The module command provides a convenient mechanism for managing which environment variables are set in your shell session. The following is a list of the basic usage of the module command:

• Check which modules are available

  module avail

• Add a module to the current environment

  module add <module>

• Remove a module from the environment

  module remove <module>

#include <stdio.h>
 
int main()
{
    printf("Hello World");
    return 0;
}

PROGRAM Hello
    PRINT *, "Hello World"
END PROGRAM Hello

The following code snippets demonstrate how to compile the above code examples use the GNU compiler suite:

gcc -o hello hello.c

gfortran -o hello hello.f90

The following code snippets demonstrate how to compile the above code examples use the Sun Studio compiler suite:

cc -fast -o hello hello.c

f90 -fast -o hello hello.f90

The above compilers include support for OpenMP. To compile an OpenMP code add the -fopenmp option. For example:

gcc -o mp_hello -fopenmp mp_hello.c

The following code snippets demonstrate how to compile the OpenMP examples use the Intel compilers:

f90 -fast -o hello hello.f90

MPI is provided using the OpenMPI libraries. To compile MPI code use the mpicc or mpif90 compilers.

To run an MPI job see the Moab guide.
