  • Communications program product involving groups of processors of a distributed computing environment
    Patent number: 5764875
    Abstract: In a distributed computing environment having a plurality of groups of processors, each processor group maintains its own set of ordered messages. A message is sent to a group of processors. In particular, a request to multicast a message is sent to a leader of the group of processors, i.e., a group leader, and the group leader assigns a sequence number to the message to be sent, thereby providing an ordered message. Then, the group leader multicasts the ordered message to the group of processors. When the processors of the group receive the ordered message, each determines whether the message is in proper sequence order. If the message is out of order for a particular processor indicating that a message has been missed, then that particular processor requests the missing message from a processor within the group.

  • System for utilizing batch requests to present membership changes to process groups
    Patent number: 5748958
    Abstract: A system for managing membership of process groups of a distributed computing environment. Requests to alter membership of a first process group are received and presented to the first process group as a batched request. However, requests to change the membership of a second process group are received and presented to the second process group serially. Thus, the manner in which requests are presented can be different for various process groups. Additionally, different types of requests can be presented to the same process group in a differing manner. For instance, requests to join a process group can be presented as a batched request and requests to leave the process group can be presented serially, or vice versa.

  • Method for group leader recovery in a distributed computing environment
    Patent number: 5704032
    Abstract: A new leader of a group of processors executing within a distributed computing environment is selected when the current group leader fails. The new group leader is selected from a membership list ordered in sequence of joins of processors to the group of processors. The selected leader is the next processor on the membership list after the failed group leader. In particular, it is the next active processor on the membership list. The group of processors is informed of the new group leader, after it is selected.
