The extended NUMA
functions
ssorNodeEx, and GetNumaProximityNodeEx differ from their unextended counterparts in that the
node number is a USHORT value rather than a UCHAR, to accommodate the potentially greater
number of nodes on a system with more than 64 logical processors. Also, the processor specified
with or retrieved by the extended functions includes the processor group; the processor specified
with or retrieved by the unextended functions is group-relative. For details, see the individual
function reference topics.
