I have 12 core boxes:
egrep -c processor /proc/cpuinfo 12 cat /proc/irq/default_smp_affinity fff
I would like to use all of the cores so my understanding is that the default_smp_affinity should be set to ffffffffffff.
echo ffffffffffff > /proc/irq/default_smp_affinity -bash: echo: write error: Value too large for defined data type
How can I make sure that all of the cores are equally used and the default_smp_affinity is set correctly?
cat /etc/issue.net CentOS release 6.5 (Final)
2.6.32-431.23.3.el6.x86_64 #1 SMP Thu Jul 31 17:20:51 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Any input is appreciated.
