Abstract
Methods to automatically prioritize input/output (I/O) for Network Function Virtualization (NFV) workloads at platform overload and associated apparatus and mechanisms. During lab or runtime workload operations, various platform telemetry data are collected and analyzed to determine whether a current workload is uncore-sensitive—that is, sensitive to operations involving utilization of the uncore circuitry such as I/O-related operations, memory bandwidth utilization, LLC utilization, network traffic, core-to-core traffic etc. For uncore sensitive workloads, upon detection of a platform overload condition such as a thermal load approaching a TDP limit, the uncore circuitry is prioritized over the core circuitry such that the frequency of the core is reduced first. A closed-loop feedback mechanism is used to adjust the frequencies of the core and uncore under various workload conditions. The mechanism enables I/O throughput to be maintained for NFV workloads, while reducing the processor thermal load.
