Abstract: A first workgroup is preempted in response to threads in the first workgroup executing a first wait instruction including a first value of a signal and a first hint indicating a type of modification for the signal. The first workgroup is scheduled for execution on a processor core based on a first context after preemption in response to the signal having the first value. A second workgroup is scheduled for execution on the processor core based on a second context in response to preempting the first workgroup and in response to the signal having a second value. A third context it is prefetched into registers of the processor core based on the first hint and the second value. The first context is stored in a first portion of the registers and the second context is prefetched into a second portion of the registers prior to preempting the first workgroup.

Abstract: A processing system monitors and synchronizes parallel execution of workgroups (WGs). One or more of the WGs perform (e.g., periodically or in response to a trigger such as an indication of oversubscription) a waiting atomic instruction. In response to a comparison between an atomic value produced as a result of the waiting atomic instruction and an expected value, WGs that fail to produce a correct atomic value are identified as being in a waiting state (e.g., waiting for a synchronization variable). Execution of WGs in the waiting state is prevented (e.g., by a context switch) until corresponding synchronization variables are released.

Abstract: A computer-implemented method for dynamic resource management can include evaluating, by at least one processor, whether a priority of one or more processes associated with a request for one or more shared resources meets a threshold condition. The method can additionally include determining, by the at least one processor and in response to an evaluation that the priority meets the threshold condition, whether the one or more shared resources is available to meet the request. The method can further include completing, by the at least one processor and in response to a determination that the one or more shared resources is available, execution of the one or more processes. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A processing system includes a scheduling mechanism for producing data for fine-grained reordering of workgroups of a kernel to produce blocks of data, such as for communication across devices to enable overlapping of a producer computation with an all-reduce communication across the network. This scheduling mechanism enables a first parallel processor to schedule and execute a set of workgroups of a producer operation to generate data for transmission to a second parallel processor in a desired traffic pattern. At the same time, the second parallel processor schedules and executes a different set of workgroups of the producer operation to generate data for transmission in a desired traffic pattern to a third parallel processor or back to the first parallel processor.
