Performance monitoring and resource management

摘要

Examples described here concern a kernel performing an application, the application being designed to write application performance values into one or more telemetry registers associated with the kernel. In some examples, one or more telemetry registers may be designed for the application to store performance measurement values from the application. In some examples, an orchestration unit can read one or more telemetry registers,which are associated with the core. In some examples, the orchestration unit selectively modifies a resource allocation to the application based on the read content of one or more telemetry registers. The usage of the kernel can be 100% whereas the performance measurements can indicate a utilization level of the application. In some examples, the performance measurement values include one or more of: an application load level, packets processed over a time interval, a number of packets lost over a time interval, a number of video frames processed over a time interval,of writing operations per second, read operations per second or a number of pending writing operations.
