> Undesired Hash collision may happen when locating process id to workers and servers using `int Cluster::Hash(int gid, int id, int flag)` in `cluster.cc`.
> For example, let us assume that there are 2 worker groups and 2 workers per group and 1 server in 1 server group, and we separate server and worker in different processes. Hash(1,0,0) and Hash(0,0,2) will get the undesired same value 2.
