Where can I configure the amount of NUMA nodes in Windows Server 2016?

 

Background: A client is testing an intel 112 core physical server (4 sockets) for a high performance computing application. The app uses OpenMP to dispatch work. 

 

Under windows 2016, the sever creates 8 Numa Nodes, under window 2012 r2, only while 4 nodes are created under windows 2012 r2. They are considering using 2012 r2, because with only 4 nodes, the app is more performant. 

 

Where are the settings controlling allocation of NUMA nodes? Guidance? Help?
