- <description>
- <warning>
- <p>This module is deprecated and will be removed in Erlang/OTP 18.</p>
- </warning>
- <p>This (experimental) module implements process groups. A process
- group is a group of processes that can be accessed by a common
- name. For example, a group named <c>foobar</c> can include a set
- of processes as members of this group and they can be located on
- different nodes.</p>
- <p>When messages are sent to the named group, all members of
- the group receive the message. The messages are serialized. If
- the process <c>P1</c> sends the message <c>M1</c> to the group,
- and process <c>P2</c> simultaneously sends message <c>M2</c>, then
- all members of the group receive the two messages in the same
- order. If members of a group terminate, they are automatically
- removed from the group.</p>
- <p>This module is not complete. The module is inspired by the ISIS
- system and the causal order protocol of the ISIS system should
- also be implemented. At the moment, all messages are serialized
- by sending them through a group master process.</p>
