Correct me if I'm wrong, but NUMA is precisely what you say, and even 
more: all cores in all processors have access to all memory.

All cores in a given processor have uniform access to this processor's 
share of memory. They can also access the other processors' shares of 
memory, but with some penalty. Hence the N in NUMA.
