1. Is my understanding correct? Running 2 agents on the same server will send the same offer twice( same offer by each agent ) and there are chances that resources will be over utilized by accepting the same offer twice by the framework.
2. May I know the settings( cgroup ) required to run 2 slaves in the same server and How does it behave?
