Hi all,
I get the following interesting message when compiling:

This happens when I change this
!$acc kernels loop independent gang (256) private(rhs)
do b = 1, nb
! some code
!$acc loop independent vector (32)
do n = 1, nn
! some code
do i = 1, ni
!some code
enddo
! some code
enddo
!some code
!$acc loop independent vector (32)
do i = 1,i2
temp = 0.0
!$acc loop independent reduction(+:temp)
do k = 1,j2
temp = temp + x(i,k,r) * y(k)
end do
z(i+i1-1) = temp
end do
enddo
to this

The weird thing is according to Minfo messages it seems to be dying much earlier in the compilation than this. Unfortunately, I may not post the full source - I’m not sure I’ll be able to produce a sanitized example in this case.
Any ideas?
Rob
ps - feel free to wack me over the head if I’m misusing gang/worker/vector statements. I’m just experimenting at this point to figure out how they best go together.
