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);
            }
        }
    }
}
