Coarray "Broadcast" produces collective abort of all ranks for larger data sets?

[kostas85]

Hello all,

When I define a derived type and try to broadcast an (coarray) array of this type I get the following message,

rank 7 in job 1 cfds_42600 caused collective abort of all ranks

exit status of rank 7: killed by signal 9

if:

1. the extend of the array of derived types is greater than a certain number (around n=600000, see code below)

2. another component is added to the derived type, in the code I have added an extra real to the derived type

uncommenting the line produced the same message

3. the extend of the array component of the type is changed(say to 40)

The following code works fine. In order to reproduce the message above you should make one of the previously

listed changes(or all). Please try it and let me know how the code worked for you.

[fortran]module my_struct type struct !real(kind(0.d0)), dimension(3) :: re ! <- Remove comment from this line, the message appears integer, dimension(2) :: in ! <- Change size from 2 to 40, the message appears end type struct interface assignment (=) module procedure equal_struct end interface contains elemental subroutine equal_struct(st1,st2) type(struct), intent(inout) :: st1 type(struct), intent(in) :: st2 st1%in = st2%in end subroutine equal_struct end module my_struct program coarrays_transfer_struct use my_struct implicit none integer :: i, n=400000 ! change n to 700000, the message appears type(struct), dimension(:), allocatable :: st type(struct), dimension(:), codimension[:],allocatable :: cost ! <- Both allocatable !type(struct), dimension(400000), codimension

:: cost ! and "explicit" fail character(5) :: fc allocate(cost(n)

) if (this_image() == 1) then allocate(st(n)) do i=1,n st(i)%in = i end do cost=st print *, ' Broadcasting ...' end if if (this_image()/=1) cost=cost[1] print *, this_image(), 'Done' sync all write(fc,'(i5)'), this_image() open(this_image(),file='ts'//trim(adjustl(fc))//'.txt') do i=1,n write(this_image(),*) cost(i)%in end do end program coarrays_transfer_struct[/fortran]

Thank you ! I really appreciate your help!

It was naive of me.. changing the stacks works fine !

that is good to know. it is easy to forget the stack size, especially when some batch systems toss out your env vars at dispatch. so many little details to look after.
