How does his code relate to "OCEAN" circa 2016 with LBL author?

[mike marchywka]

I'm doing a literature search looking for a BSE to go with JDFTX. It looks like

the BerkleyGW code will be part of that but curious how it relates to the code

described in [1] below.  Apaprently there is a very recent all-electron code

[2] but not sure how open it is lol. 

Right now I'm stuck playing with libs trying to get the fortran to link with fftw3 lol.

Thanks.
