I noticied that in these servers, the smp_affinity is not a sinle mask value, insteads is a series of "comma" separated values. Can someone help me understand how to interpret these values and set the mask? =20 [root@g1 linux-2.6.18]# cat /proc/irq/10/smp_affinity=20 00000000,00000000,00000000,00000000,00000000,00000000,00000000,00000001 I also cheched on a 2 DUAL core Intel servers on HPDL380 G5 servers with redhat 4.
