Dear Bo Xiao:
your sustem is big and periodic (lot of overlaps);
nobody knows how big your computer is.
Are you happy with your "regular" electronic structure calculation
(on a k-mesh of your ~130 points)?
If yes, then the band structure is nothing special,
it's just a calculation with different k-points (~300 in your case) ...
If it takes too long you can cut in in pieces;
you don't have to run it in a single run.

Beside the point: are you sure SZP is good for your purposes?

Best regards
