No.

The rx6600 is *not* a NUMA system. It is a UMA system.

Only the cell-based systems (rx7640, rx8640 and Superdome) are non-uniform memory access capable. (and even then only in multi-cell partitions).

To see if a given system is NUMA or not, run:

mpsched -s

If the locality domain count is > 1, your system is NUMA.

NUMA will likely become much more important when systems based on Tukwila are released with on-board memeory controllers. This will mean every multi-socket system is a NUMA system (like all AMD64-based systems are right now, although most folks choose not to take advantage of that).
