The operation of initializing is performed to set up a transfer of processing code for the game from one processing nods to another processing node. The method includes defining an internal communication channel between the two or more processing nodes for exchange of state information of the game. The exchange of state information is performed to enable shared processing of the game by the two or more nodes.

Abstract: A method is disclosed for requesting data in a cloud gaming system that includes a cloud storage system and a cloud compute system, each of which has a respective peripheral component interconnect express (PCIe) interface and a respective computer memory. The cloud gaming system includes a PCIe switch connected to both the PCIe interface of the cloud storage system and the PCIe interface of the cloud compute system. The PCIe switch exposes a doorbell register that is monitored by the cloud storage system. The cloud compute system writes to the doorbell register, which causes an interrupt to fire on the cloud storage system. The cloud storage system handles the interrupt, which directs the cloud storage system to read a message from a specified computer memory location. The message directs the cloud storage system to read requested data from a storage device accessible by the cloud storage system.

Abstract: Systems and methods are configured to adjust the timing of rendered frame scanout in response to fluctuations in a variable frame rate at which source frames are rendered.

Abstract: Systems and methods for downloading and updating save data to a data center are described. Save data is downloaded from a cloud storage to the data center before play of a game to cache the save data in the data center. Any updates to the save data that occur during a play of a game are stored in the data center and are uploaded to the cloud storage. Next time, a user desires to access the game, there is no need to transfer the updates to the data center from the cloud storage.

Abstract: Methods and systems for predicting instant play includes pre-loading one or more instances of select ones of games on one or more game consoles on a cloud game server. The loading of instances is based on usage history of the games. Users are assigned to select ones of the instances of the games loaded on the one or more game consoles, in response to user interaction detected at the select ones of the games exceeding a pre-defined threshold value. User interactions are monitored at the instances of the select ones of games assigned to the users. Based on the monitored interactions, the number of instances of the games loaded on the one or more game consoles are dynamically adjusted. The dynamic adjustment includes scaling up or scaling down the number of instances of the games loaded on the one or more game consoles.

Abstract: Methods and systems to identify options of secondary client devices for a device handover of game play include establishing a session of game play of a game for a primary client device by executing the game on a server and streaming video frames to the primary client device. A profile is generated for each secondary client device that is identified to be local to the primary client device. A handover option is provided to the primary client device during game play, identifying one or more of the secondary client devices, based on the profile. A selection of a secondary client device from the handover option causes pausing of the streaming of video frames to the primary client device, accessing the game state for the game, and resuming game play using the secondary client device.

Abstract: In a multi-GPU simulation environment, frame buffer management may be implemented by multiple GPUs rendering respective frames of video, or by rendering respective portions of each frame of video. One of the GPUs controls HDMI frame output by virtue of receiving frame information from the other GPU(s) and reading out complete frames through a physically connected HDMI output port. Or, the outputs of the GPUs can be multiplexed together.

Abstract: Aspects of the present disclosure describe automatically changing an output mode of an output device from a first output mode to a latency reduction mode. An initiation signal and the output data may be received from a client device platform or a signal distributor. Upon receiving the initiation signal, the output device may change the output mode from the first output mode to the latency reduction mode. Thereafter, the output device may receive an end latency reduction mode signal. The output device may then revert back to the first output mode. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
