why only one cpu is running (100% full load) when I execute " python eval.py"

[lemonsee]

I have a machine that have 16 CPUs ,but only one cpu is running (100% full load) when I execute " python eval.py",why?

I have set the config.py like this :

 session_conf = tf.ConfigProto(
              device_count={'CPU':8},
          intra_op_parallelism_threads=4,
          log_device_placement=False
      )

here is some information about devices :

print(device_lib.list_local_devices())
[name: "/cpu:0"
device_type: "CPU"
memory_limit: 268435456
locality {
}
incarnation: 12312707312159520189
]

I hope that all CPUs in my machine can be used to speed up the evaluation . I need help , thx !!!
