[QE-users] Possible problems of using "memory = 'small'"

[Lenz Fiedler]

Hi users,

I hope this is not a duplicate, but I am trying to work with a big cell 
and am running into memory issues. I tracked the issues (partially) down 
to ggen, and found that by setting "memory" to "small" (as suggested in 
the comments in the code) the problems disappeared, because the 
no_global_sort was now set to true.

My question now is: are there any known limitations to this? Anything 
one should be careful about when using "memory = 'small'" or can I just 
use it whenever?

Kind regards,
