Latest Patents

One of Lei Yang's latest patents is titled "Programming model for resource-constrained scheduling." This technology enhances the GPU compute model by providing system-provided data marshalling characteristics of graphics pipelining. It aims to increase efficiency and reduce overhead. The patent introduces a simple scheduling model based on scalar counters, such as semaphores, which abstract the availability of hardware resources. Resource releases can be managed programmatically, allowing a system scheduler to track the states of these counters to make informed work launch decisions. The semantics of the counters are defined by applications, which can utilize them to represent various resource availability metrics.

Another significant patent is "Simultaneous compute and graphics scheduling." This invention involves a parallel processing unit, such as a GPU, which includes a hardware scheduler and arbiter. This system allows for the simultaneous execution of graphics and compute work on a SIMD/SIMT processing unit. The processing unit can operate in either a graphics-greedy or compute-greedy mode, depending on monitored performance metrics. The hardware arbiter can selectively launch compute or graphics work items based on user-configured thresholds, optimizing resource utilization.
