On a Cray SV1EX system it does make sense.  It was based on the YMP
architecture which had been around for a long time and could only 
address 32GB of RAM.

The last version of the memory modules could take it upto 128GB so the
last 96GB is only available as solid state disk, disk buffer or swap.  
It can run at 80GB/sec memory to memory so it made swapping reasonable.
