ifort options -openmp and -qopenmp

I work in three computers, two servers (let's call them grits and cassoulet) and my own Mac machine. Well, I found out that the options to use OpenMP in the Intel Fortran compiler (ifort) are different depending on the compiler version:

• grits: ifort 15.0.3: -qopenmp
• Mac: ifort 15.0.2: -qopenmp

but...

• cassoulet: ifort 14.0.3: -openmp

According to the documentation for for ifort, the option -openmp is deprecated .
