Nanosecond-scale power resource allocation method and system for microservices

A method for allocating microservice-oriented nanosecond power resource, wherein the method comprising:

• leveraging an auto power budgeting module which distributes the limited power resource to each microservice according to its power-performance model while deploys an agile power regulation module that bypasses power management and control procedures at a server system layer;
• invoking an on-chip voltage regulation circuit to execute power allocation decisions for each microservice;
• finally, coordinating the auto power budgeting module and the agile voltage regulation module to achieve optimal power allocation through a transparent mapping mechanism;
• the auto power budgeting module includes creating a power-performance model to describe performance of different microservices in a dynamic environment;
• the power-performance model reflects relationship between a response time and an allocated power consumption, which quantify variability of power allocation of the different microservices, which allocates power resources to most influential microservices that prioritizes power resource budget for the most influential microservices, which maximize power resource utilization without affecting performance of entire application;
• the agile power regulation module is implemented with a set of customized registers, a daemon process for listening to status of the registers in real time, and a system call function for assigning power budgets to the different microservices;
• the transparent mapping mechanism enables recording and updating of tuning results by means of hardware labels and software labels;
• hardware labels are used to identify the different microservices executing on a processor;
• software labels are used to distinguish the different microservices in data center and to track running status of the different microservices.
