No - if you got this far, cpusets are working for you.

You would need NUMA if you had multiple memory nodes.

I'm guessing you have one collection of RAM modules,
all equally distant from the processors, which is not
a NUMA (Non-Uniform-Memory-Architecture) system.

I only mentioned NUMA because if you did have NUMA
hardware, then you would need to CONFIG it into to
your kernel to make full use of your multiple memory
nodes.  I doubt that applies to you.

It looks like you have multiple (4 logical with HT)
CPUs, numbered 0, 1, 2, and 3, and one Memory Node,
numbered 0.

Cpusets should work for you - just "echo 0", not "echo 1"
into the "mems" files.  Your one and only Memory Node
is numbered "0", not "1".

Actually, make that "/bin/echo", not "echo", so you can
see the error messages.
