 I have set up a total of 1024 Hugepages (that is, allocated 512 2M pages to each NUMA node).

    taskset 0x10 ./l2fwd -c 0xff0 -n 2
 
+.. Note: Instead of '-c 0xff0' use the '-l 4-11' as a cleaner way to define lcores.

 In this way, the hugepages have a greater chance of being allocated to the correct socket.
 Additionally, a ``--socket-mem`` option could be used to ensure the availability of memory for each socket, so that if hugepages were allocated on
 the wrong socket, the application simply will not start.
