Abstract
A computing system group processing architecture that facilitates asymmetric processing at different computing nodes within a group or cluster of nodes. Nodes within a group are assigned to subgroups. Each node in a subgroup performs similar processing, but nodes in different subgroups are able to perform different processing for the same group level protocol. All nodes monitor processing completion votes that are cast by all nodes, and node in subgroups that finish processing before other subgroups synchronize to the processing of those other subgroups by casting dummy votes during vote rounds of other subgroups that are still processing their subgroup protocol.
