Well I can, but the fact that this is an assert() makes me think it is
intentionally not supporting 32bit architectures.  Upstream has been
rather opinionated that this code is geared at high-end supercomputers
only.

We might have to restrict the architecture list to 64bit, I doubt just
removing the above assert() will be the end of the story.
