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. I get the
same error.
You can find the code in the attachment.
probably there is something wrong with ompi configuration
What do you think?
Again, thanks and thanks a lot
Diego
