kmaps is gone

Post by fgoudreault »

Hi, I noticed (following recent developments of EPW), that the input variable kmaps is not recognized anymore. Was it replaced by a different variable or it is gone for good?

Thanks,

Felix Goudreault

Hi Felix,

The input flag "kmaps" is removed for the better performance and now the code takes care the mapping internally.

Best,
Hari

Dear Felix Goudreault:

I would like to add one thing to Hari's answer.

Compared with EPW v5.3.1, there is no change in the part related to the generation of mapping table for folding and in EPW v5.4, kmaps is just removed for the purpose of simplification of input variables.

Compared with EPW v5.2, in EPW v5.3, the generation of mapping table for folding was optimized and due to this change we don't need to read the mapping table previously saved.

So in EPW v5.4, in order to reduce the number of input variables and simplify the restart kmaps is removed and now we always generate the mapping table on the fly if it is necessary.

Sincerely,

H. Lee
