Hi there,
I am stuck by a strange problem when compiling with
-fopenacc -foffload=nvptx-none=-march=sm_75
a code that used to work until relatively recently, is now sistematically
throwing the following (or similar) error:
libgomp: Cannot map target functions or variables (expected 25, have 20)
The error comes from allocation of a vector in a derived typein a test
program of a complex library; the vector is then subject to something like
this
subroutine oad_sync_space(x)
implicit none
class(oad_vect), intent(inout) :: x
if (allocated(x%v)) then
call d_oad_create_dev(x%v)
end if
contains
subroutine d_oad_create_dev(v)
implicit none
real :: v(:)
!$acc enter data copyin(v)
end subroutine d_oad_create_dev
end subroutine oad_sync_space
and the failure I showed happens on the enter data directive.
Now, I have partially cheated: the above code is extracted from an attempt
to produce a reduced test case: if I only keep the reduced code (with the
reduced type/class definitions) it works, but when I link with the full
library code it fails.
Do you have any suggestions on how to go about debugging this?
Should I ask on a different mailing list?
Full code available if anybody wants to take a look at it.
Thanks a lot
Salvatore
