Cpus_allowed_list Issue In RHEL6.4

Hi All,

I am using RHEL 6.4 on a Dell Server with 32 cores.

But in the Cpus_allowed_list only 30 cores are available. Why is that?

See the snippet from cat /proc/self/status:
Cpus_allowed: 7fff7fff Cpus_allowed_list: 0-14,16-30

The allowed list is same for the init process as well (see below). I didn’t see this issue, in RHEL 6.2.

Why is that? Is there a way to change it?
