Abstract:

[Objective] Under the background of the project of “East-West Computing Requirement Transfer”, the super-computing resources distributed in different regions will be scheduled and managed. In order to avoid the problem of busy and unevenly distribution of computing resources, it is necessary to develop a multi-center task scheduling system by investigating the runtime characteristics of typical applications to achieve unified management of the national high-performance computing environment. [Methods] Firstly, the log data about application execution at several national supercomputing centers are collected and the database for the application log data is established. Secondly, by taking the user resources demand and the resource usage characteristics of typical applications into consideration, a machine learning framework is established to accurately depict the application execution features. Then migration of HPC applications across clusters using containers is implemented. Finally, a task scheduling system based on application-aware resource scheduling optimization is developed. [Results] This system provides powerful technical support for services and efficient operation of the national high-performance computing environment. [Conclusions] The application-aware method for computing power scheduling optimization is expected to effectively improve the reliability, availability, and maintainability of the “East-West Computing Requirement Transfer” project.
