The IBM does things differently. Invoking xlf means you have fixed format while xlf90 means free format. You can override with -qfixed or -qfree=f90. The big nasty is that by default it won't accept .f90 as a valid file extension; you can force it with -qsuffix=f=f90. For MPI code you invoke mpxlf or mpxlf90 while for OpenMP code you invoke "xlf_r -qsmp=omp".
