1. no binding support - indicated by a negative return code from get_cpubind
2. binding supported, but not bound - the bitset returned by get_cpubind is the same as the available cpuset
3. binding supported and bound - bitset from get_cpubind is a subset of available cpuset
4. only one cpu is available - in this case, get_cpubind matches the available cpuset, but we are effectively bound
