Subject: Opteron NUMA/SMP question

The quad opteron machines are NUMA.  If a quad owner upgrades to dual-core
chips, are the dual cores SMP?  If so, you have an SMP/NUMA combination.  Seems
like someone answered this before, but it was not clear in my mind.

IIRC, Bob said that a NUMA-aware program would need some modification to take
full advantage of a NUMA/SMP combination as described above.

Am I understanding this correctly?
