Dear developers:
I would like to know the parallelization schemes in different runlevels.
Specifically, I wonder how the calculation is parallelized in "-p" and "-g" run levels.
Is it parallelized over k points or bands? Or both?
Sincerely,
Hyungjun Lee

Re: parallelization in Yambo
Dear Hyungjun,
the parallelization is on q points, or |nk> states in the -g n runlevel. If you run a gamma point only calculation it is on bands,
anyway the parallelization structure will be totally changed in the next release of the code.
Best,
Daniele
