US Patent 7634604 Systems for generating synchronized events and images

A system and method for generating sequences of triggered events and for generating global interrupts in a clustered computer graphics system is provided. In a sender-receiver dichotomy, one node is deemed the sender and the others act as receivers. The sender determines trigger values for each of the nodes in the system in order to achieve a particular operation sequence. In addition, a synchronization signal generator is provided to synchronize a timing signal between the sender and receiver nodes. Further, the sender designates one or more receiver nodes and causes them to turn on an interrupt enable register. In this way, the receiver nodes are able to be interrupted by the sender.
