It might probably better have 'node' instead of 'numa' as in the 
option name '--per-node' as in the table header, like this:

    #           time node     cpus             counts unit events
         1.000542550 0        20          6,202,097      cycles
         1.000542550 1        20            639,559      cycles
         2.002040063 0        20          7,412,495      cycles
         2.002040063 1        20          2,185,577      cycles
         3.003451699 0        20          6,508,917      cycles
         3.003451699 1        20            765,607      cycles
   ...
