Please, someone could explain more in details what is written in the release 
notes for the 5.3 ?

B.6 *Parallelism over bands is available for GW*. See the input variable 
gwpara.
   This parallelism allows for memory savings, and is quite efficient.
   At present, either the band parallelism or the k point parallelism is 
available
   in GW, they cannot be used simultaneously.
   This has been implemented by R. Shaltaf.
   (Note, however, that parallelism over bands in GW is not compatible with 
nsppol=2 as of v5.3.0)
   Automatic test for band parallelism : paral#N

and the corresponding action of the parameter gwpara=2 : parallelisation on 
bands.

I'm not sure to understand : "bands" stand for matrix elements ? 
wavefunctions ?

Thanks a lot,

Philippe
