Provided Compilers

Compilers are available on Bell for Fortran, C, and C++. Compiler sets from Intel and GNU are installed.

Detailed documentation on each compiler set available on Bell follows.

On Bell, the following set of compiler and libraries for building code are recommended:

GCC 9.3.0
OpenMPI

To load the recommended set:

$ module load rcac
$ module list

More information about using these compilers:

GNU Compilers

The official name of the GNU compilers is "GNU Compiler Collection" or "GCC". To discover which versions are available:

$ module avail gcc

Choose an appropriate GCC module and load it. For example:

$ module load gcc

An older version of the GNU compiler will be in your path by default. Do NOT use this version. Instead, load a newer version using the command module load gcc.

Here are some examples for the GNU compilers:
Language	Serial Program	MPI Program	OpenMP Program
Fortran77	`$ gfortran myprogram.f -o myprogram`	`$ mpif77 myprogram.f -o myprogram`	`$ gfortran -fopenmp myprogram.f -o myprogram`
Fortran90	`$ gfortran myprogram.f90 -o myprogram`	`$ mpif90 myprogram.f90 -o myprogram`	`$ gfortran -fopenmp myprogram.f90 -o myprogram`
Fortran95	`$ gfortran myprogram.f95 -o myprogram`	`$ mpif90 myprogram.f95 -o myprogram`	`$ gfortran -fopenmp myprogram.f95 -o myprogram`
C	`$ gcc myprogram.c -o myprogram`	`$ mpicc myprogram.c -o myprogram`	`$ gcc -fopenmp myprogram.c -o myprogram`
C++	`$ g++ myprogram.cpp -o myprogram`	`$ mpiCC myprogram.cpp -o myprogram`	`$ g++ -fopenmp myprogram.cpp -o myprogram`

More information on compiler options appear in the official man pages, which are accessible with the man command after loading the appropriate compiler module.

Intel Compilers

One or more versions of the Intel compiler are available on Bell. To discover which ones:

$ module avail intel

Choose an appropriate Intel module and load it. For example:

$ module load intel

Here are some examples for the Intel compilers:
Language	Serial Program	MPI Program	OpenMP Program
Fortran77	`$ ifort myprogram.f -o myprogram`	`$ mpiifort myprogram.f -o myprogram`	`$ ifort -openmp myprogram.f -o myprogram`
Fortran90	`$ ifort myprogram.f90 -o myprogram`	`$ mpiifort myprogram.f90 -o myprogram`	`$ ifort -openmp myprogram.f90 -o myprogram`
Fortran95	(same as Fortran 90)	(same as Fortran 90)	(same as Fortran 90)
C	`$ icc myprogram.c -o myprogram`	`$ mpiicc myprogram.c -o myprogram`	`$ icc -openmp myprogram.c -o myprogram`
C++	`$ icpc myprogram.cpp -o myprogram`	`$ mpiicpc myprogram.cpp -o myprogram`	`$ icpc -openmp myprogram.cpp -o myprogram`

More information on compiler options appear in the official man pages, which are accessible with the man command after loading the appropriate compiler module.
