A shadow command ring is described for graphics processor virtualization. In one example a command batch is loaded from a virtual machine of a general purpose processor into a physical command ring of a graphics processor. A physical tail pointer register of the graphics processor is set and the command batch and the physical tail pointer are trapped at a mediator. The mediator copies the trapped command batch and the physical tail pointer in a shadow command ring and sets a virtual tail pointer. The execution of the physical command ring is monitored and if an error is determined then the physical command ring is cleared and reloaded using the shadow command ring.

Shadow command ring for graphics processor virtualization

Various embodiments are directed to techniques for dividing compressed video data into portions for load balancing or redundancy among multiple video transcoders. A device includes an analysis component to analyze NAL units of compressed video data representing a motion video to identify a GOP refresh, and to compare a period of time represented by frames of the motion video following the GOP refresh to a maximum; a division component to divide the compressed video data at a first point coincident with the GOP refresh to define a start of a compressed video portion, and at a second point to define an end of the compressed video portion to include frames of the motion video representing a shorter period of time between the first and second points than the maximum; and an assignment component to assign the compressed video portion to a transcoding device. Other embodiments are described and claimed.
