Latest Patents

One of Ahmed Eltantawy's key patents is titled "Thread scheduling on SIMT architectures with busy-wait synchronization." This patent describes a system and method that detects when a group of threads has executed a spin-inducing branch in a SIMT processor. The invention focuses on scheduling groups of threads based on this detection, marking the group as backed-off and deprioritizing it for scheduling. When the group is eventually scheduled, a back-off counter is initialized and decremented with each clock cycle. The system prevents the group of threads from being scheduled again if the spin-inducing branch is executed before the counter reaches zero. Additionally, the patent outlines a hardware system and method for labeling spin-inducing branches, which determines when a profiled thread is in a spinning state and detects backward branch executions while spinning. A confidence level can be utilized, increasing with each execution of a backward branch during the spinning state.
