Abstract: In one embodiment, a device receives information regarding a data set to be processed by a map-reduce process. The device generates a set of virtual clusters for the map-reduce process based on network bandwidths between nodes of the virtual clusters, each node of the virtual cluster corresponding to a resource device, and associates the data set with a map-reduce process task. The device then schedules the execution of the task by a node of the virtual clusters based on the network bandwidth between the node and a source node on which the data set resides.

Abstract: A video conference server receives a plurality of video frames including a current frame and at least one previous frame. Each of the video frames includes a corresponding image and a corresponding depth map. The server produces a directional distance function (DDF) field that represents an area surrounding a target surface of the object captured in the current frame. A forward transformation is generated that modifies the reference surface to align with the target surface. Using at least a portion of the forward transformation, a backward transformation is calculated that modifies the target surface of the current frame to align with the reference surface. The backward transformation is then applied to the DDF to generate a transformed DDF. The server updates the reference model with the transformed DDF and transmits data for the updated reference model to enable a representation of the object to be produced at a remote location.

Abstract: In one embodiment, data indicative of the size of an intermediate data set generated by a first resource device is received at a computing device. The intermediate data set is associated with a virtual machine to process the intermediate data set. A virtual machine configuration is determined based on the size of the intermediate data set. A second resource device is selected to execute the virtual machine based on the virtual machine configuration and on an available bandwidth between the first and second resource devices. The virtual machine is then assigned to the second resource device to process the intermediate data set.
