Compilation of parallel OpenMP code (Fortran, C/C++)

Compiling an OpenMP program with Intel compilers is done by specifying the option -qopenmp as shown in the example below:

ifort -qopenmp source.f90 

icc -qopenmp source.c

icpc -qopenmp source.C

If you compile and link separately, you must specify the option -qopenmp again during linking. For example:

ifort -c -qopenmp source1.f
ifort -c source2.f
icc -c source3.c
ifort -qopenmp source1.o source2.o source3.o

info

The execution of an OpenMP program must be done in batch (via the command srun or a SLURM job) to avoid saturating the login node.
