Dear Diego, Instead of instantly going about using cartesian communicators you should try and create a small test case, something like this:
I have successfully runned this small snippet on my machine. As I state in the source, the culprit was the integer address size. It is inherently of type long, whereas you used integer. Running it (with ONLY 2 processors) should print: 1 1.0000000000000000 1.0000000000000000 11.000000000000000 11.000000000000000 Please notice the other things I comment on, they can turn out to be important! For instance, try this: real(dp) :: a a = 0.2 print *,a a=0.2_dp print *,a Try and understand why the output is not as expected! Also try and understand why this has no problems: real(dp) :: a a = 1. print *,a a=1._dp print *,a 2014-10-03 15:41 GMT+00:00 Diego Avesani <diego.aves...@gmail.com>: > Dear Nick, > thanks again, I am learning a lot and do not be afraid to be rude. > > > > Diego > > > On 3 October 2014 17:38, Diego Avesani <diego.aves...@gmail.com> wrote: > >> Dear Jeff, Dear Nick, >> the question is about, inserting the FLAG for using -r8 >> >> Now I have written a simple code with select_kind to avoid -r8.
