Memory allocation using regular repetitions. #224

Closed arondahl closed 9 months ago

arondahl commented 9 months ago

Hi,

I noticed there is a large disparity of memory use, when generating reference repetitions using perpendicular v1&v2 vectors in gdstk.Repetition() versus using vectors, which are not perpendicular. I was wondering why this is and also whether there is a work around?

Best, Aron Dahlberg

Are you talking about runtime memory usage or the size of the resulting GDSII file? Both are expected to be larger in the non-orthogonal case, but the largest difference will be in the saved file, because the GDSII format does not support this type of array.

Yes, in that case you have to use the OASIS format to see any gain.
