Adaptive scheduling of memory and processing-in-memory requests

Adaptive scheduling of memory requests and processing-in-memory requests is described. In accordance with the described techniques, a memory controller receives a plurality of processing-in-memory requests and a plurality of non-processing-in-memory requests from a host. The memory controller schedules an order of execution for the plurality of processing-in-memory requests and the plurality of non-processing-in-memory requests based at least in part on a processing-in-memory request stall threshold and a non-processing-in-memory request stall threshold. In response to a system switching (e.g., from executing processing-in-memory requests to executing non-processing-in-memory requests or from executing non-processing-in-memory requests to executing processing-in-memory requests), the memory controller modifies the processing-in-memory request stall threshold and the non-processing-in-memory request stall threshold. The memory controller continues scheduling an order of execution for subsequent requests received from the host using the modified stall thresholds.
