SGI systems had extremely discontiguous memory (they used some high
order physical address bits in the tens/hundreds of terabyte range for the
node number ... so there would

Well as far as I can tell it was not even used 12 or so years ago on
Itanium when I worked on that stuff.
My notes tell that on UP ia64 (RX2620), !NUMA was broken with both
SPARSEMEM and DISCONTIGMEM. NUMA+SPARSEMEM or !NUMA worked. Even
NUMA+DISCONTIGMEM worked, t
