it is. You can have parallelization on plane waves, parallelization on the k-points (those used in the calculation of the self-consistent charge density) but there are no other parallelization levels in the phonon code. In particular, there is no parallelization on either the node patterns or the q-points (those used to calculate the phonon dispersions). It is relatively easy to implement them and sooner or later it will be done, since it is very useful for execution on the so-called "grid" (large clusters of loosely coupled machines that appear as a single machine to the user) Paolo -- Paolo Giannozzi, Democritos and University of Udine, Italy
