title: Does redis bind to CPU cores automatically?
body: <p>I have a server with 32 logical cores(16 physical cores and hyper-thread enabled) and have 8 redis instances on it. It seems that only 16 cores, id from 0 to 7 and 16 to 23, are used and other 16 cores are idled. It shows the cpu affinity mask for any redis process is FFFFFFFF(from taskset -p pid).</p>
  
  <p>So I wonder that the cpu affinity has been set automatically in redis?</p>
  
  <p>Thanks</p>
