Abstract:
1. A multi-node computer graphics system comprising: a master node capable of executing a graphics application; a plurality of render nodes configured to collectively render a graphics image, in response to graphics data communicated from the master node; logic associated with the master node that, when implemented by the master node, communicates graphics data to the plurality of render nodes in a packet by multicast; logic associated with the master node that, when implemented by the master node, determines whether a predetermined number of render nodes have acknowledged receipt of the packet communicated by multicast, where the predetermined number is a plurality less than the number of all render nodes that comprise the plurality of render nodes; and logic associated with the master node that, when implemented by the master node, retransmits the multicast packet by multicast to the plurality of render nodes, if the predetermined number of render nodes have not acknowledged receipt of the packet communicated by multicast within a given time, and not retransmitting the packet otherwise.
