Abstract
Embodiments of the present invention are broadly directed to novel systems and methods for providing reliable multicast of data in a multi-node graphics system. In accordance with one embodiment of the invention, a multi-node computer graphics system is provided comprising a master node capable of executing a graphics application and a plurality of render nodes configured to collectively render a graphic image, in response to graphics data communicated from the master node. The embodiment further comprises logic associated with the master node for communicating graphics data to the plurality of render nodes in a multicast packet. Additional logic, associated with the master node, is provided for determining whether a predetermined number of render nodes have acknowledged receipt of the multicast packet. The embodiment further comprises logic associated with the master node for re-transmitting the multicast packet to the plurality of render nodes, if the predetermined number of render nodes have not acknowledged receipt of the multicast packet within a given time.
