distribution of memory for coarray

[Yuri1]

Whether it is possible to allocate for a array of coarray on different images the different size?
I have tested a following example, but it does not work:

module moduls
real(8), allocatable:: Z(:,:)[:]
! d - for transfer of dimension of matrix Z
integer :: d

end module moduls

program main
use moduls
np = this_image()
call impedance! Allocation of memory and initialization of matrix Z
sync all

if (np ==1) then
m = d[4]
print*,'check Z on image', m
do j = 1,m
write(*,'(f6.2)' ) (z(j,n)[4], n=1,m)!
enddo
sync images(*)
else
sync images(1)
endif
end program main

subroutine impedance
use moduls
np = this_image()
d = np
allocate( Z(d,d)

)
!initialization of matrix Z
do i = 1,d
do j = 1,d
Z(i,j) = real(i)
enddo
enddo

if (np == 4) then
print*,'input Z on image', d
do j = 1,d
write(*,'(f6.2)' ) (z(j,n), n=1,d)
enddo
endif
return
END subroutine impedance

Result: wrong transfer of a array

input Z on image 4
1.00 1.00 1.00 1.00
2.00 2.00 2.00 2.00
3.00 3.00 3.00 3.00
4.00 4.00 4.00 4.00
check Z on image 4
1.00 2.00 3.00 4.00
2.00 3.00 4.00 1.00
3.00 4.00 1.00 2.00
4.00 1.00 2.00 3.00

Where a error?

No, that is not allowed.

"The values of corresponding bounds and corresponding cobounds shall be the same on every image."

However, the standard also says that "The processor is not required to detect violations of the rule that the bounds are the same on all images".

Thanks for the detailed answer.

Sincerely,
