Summary: Undesired Hash collision when locating process id to
workers and servers
Key: SINGA-141
URL: https://issues.apache.org/jira/browse/SINGA-141
Project: Singa
Issue Type: Bug
Environment: universal
Reporter: Wang Ji
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.
