Abstract
An inventive protocol for communicating between a management processor and host processors allows for the cooperative management of resources among host processors within a partition and also among a set of partitions in a computer system, wherein each partition may function under an instantiation of an operating system with a group of host processors. The protocol employs a message passing system using mailbox pairs in fixed but moveable or relocatable locations within the computer system shared memory. The messages share a format having specific codes or descriptors that act as codes for coordination of message interpretation. These codes include at least a validity flag and a sequence enumerator, and in a response message of a request/response message pair, a status indicator. Additionally, routing codes and function codes and code modifiers may be provided. Specific implementation details and messages are described to enable the smooth functioning of complex multiprocessor systems.
