After loading Intel 13.cs module, why is mpicc/mpicxx/mpif90 still not using Intel compiler?

Please note that Intel MPI compilers have un-conventional names. After loading Intel 13.cs module (module load intel/13.cs), in order to use Intel compiler to compile MPI programs, you must use

• mpiicc for C programs
• mpiicpc for C++ programs
• mpiifort for Fortran programs

If you use the conventional mpicc, mpicxx or mpif90, GNU compilers are used. See Intel MPI compilers for details.
