I understand that - I was questioning if that is universally true or not. IF we
are guaranteed that nobody with a Cray ever renames pmi_cray.h to pmi.h, THEN
your check will be fine. Otherwise, we can’t trust it.
And I seem to recall that the earlier Crays, at least, didn’t have this naming
distinction - or at least, not at LANL. Hence my question.
