Examples

The following example shows how to display all the NUMA nodes on the local instance of SQL Server and the CPUs that belong to each NUMA node.

using System;  
using Microsoft.SqlServer.Management.Smo;  

namespace samples  
{  
    class Program  
    {  
        static void Main(string[] args)  
        {  
            Server dbServer = new Server("(local)");  
            dbServer.Refresh();  
            foreach (NumaNode node in dbServer.AffinityInfo.NumaNodes)  
            {  
                //Display the AffinityMask, GroupID and ID of  
                //each NUMA node.  
                Console.WriteLine("AffinityMask: {0}\n" +  
                                  "GroupID:      {1}\n" +  
"ID:           {2}\n",  
                    node.AffinityMask.ToString(),  
                    node.GroupID, node.ID);  
                //Display the ID of each CPU that belongs  
                //to this NUMA node.  
                Console.Write("CPUS          :");  
                foreach(Cpu cpu in node.Cpus)  
                    Console.Write("{0} ", cpu.ID);  
            }  
        }  
    }  
}  

Remarks

Access to the NumaNode object is though the AffinityInfo object that is contained in the Server object.
