Get compatible with other starpu applications regarding mpi tags

If I understand well, chameleon currently considers to be the only starpu application at runtime, so that any mpi tags between 0 and STARPU_MPI_TAG_UB can be booked by chameleon.

If this is correct this means that chameleon cannot be called concurrently to other applications using starpu right ?

Looking to the starpu documentation, there are starpu functions starpu_mpi_tags_allocate and starpu_mpi_tags_free to help users managing mpi tags. But this seems not used in chameleon.
