AN!Wiki :: CPG
CPG is an acronym for Closed Process Group", which is a component of the Red Hat Cluster Services.
The closed process group is a small process layer on top of the totem protocol provided by corosync. It handles the sending and delivery of messages amongst nodes in a consistent order. It adds PIDs and group names to the membership layer. Only members of the group get the messages, thus it is a "closed" group.
The ordered delivery of messages among cluster nodes is referred to as "virtual synchrony".
