In planewave mode I guess we also can only parallelize over (reduced?) k-points, spins, and bands. We may have to manually set the right numbers for these to match the numbers of CPUs.
*To get parallelization over bands, we can at the moment only use the rmm-diis eigensolver (cg and davidson don't work).
*The number of bands must be divisible by the number of CPUs, according to Jens Jurgen.
*At the moment there is no dipole correction in planewave mode.
*Density mixing is still done in real-space
