dp mode
 

Hi, Does bouble precision mode influences on memory reqirement? If yes, in what scale?

Re: dp mode
 

Yes. In Layman terms, Double precision calculations typically store more digits than single precision ones. For instance, 7.5 / 3.2 would be for:

Single Precision: 2.34

Double precision: 2.34375

Benchmark studies will give you a better idea for problems that are scaled-up.
