QOS TRAFFIC CLASS LATENCY MODEL FOR JUST-IN-TIME (JIT) SCHEDULERS

Abstract:

The memory sub-systems of the present disclosure discloses a simulator to simulate a QoS latency model for a just-in-time (JIT) scheduler. In one embodiment, a system receives a workload profile specifying a sequence of memory operations, wherein each memory operation is associated with a type of the memory operation. The system identifies a traffic class associated with each memory operation of the sequence of memory operations. The system queues each memory operation of the sequence of memory operations, based on the traffic class associated with the memory operation, in a scheduling pool of a number of scheduling pools. The system selects, based on a quality of service (QoS) policy, from the scheduling pools, one or more memory operations to be serviced within a scheduling time frame. The system determines, based on a latency profile, latency periods for each memory operation of the one or more memory operations.
