Re: how to bind single interface with more than one cpu

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  Hi,

I tried to change value in interface interrupt's smp_afinity value

as per my understanding , smp_afinity values

1 for cpu0
2 for cpu1
4 for cpu2
  8 for cpu3
  that way cpu0+cpu1 = 1 + 2 = 3

so i set different values for test .but each time it only binds with 
single cpu from cpu0 / cpu1 / cpu2 or cpu3.

i also start cpuspeed service and irqbalance --oneshot.

But same result.i am not able to use  more than 1 cpu for single interface.

Regards,
Benjo
