E级高性能计算机系统中监控分系统的挑战与设计

Monitoring subsystem for exascale HPC systems:Challenges and design

随着E级高性能计算机系统组装密度成倍增加,结点规模不断扩大,监控分系统在可扩展性、可靠性、可服务性和高效运维上面临巨大挑战。针对这些挑战,从架构、网络、功能和运维4个方面介绍了监控分系统的设计思路,并通过原型系统验证了部分设计的可行性与优势,对未来E级系统的构建具有较大的支撑作用。

The High-Performance Computer(HPC)systems built for future Exascale computing require a several-times increase of assembly density,along with the large expansion of node scale.This presents huge challenges for HPC monitoring subsystem in terms of scalability,reliability,serviceability,and maintenance.In response to these challenges,this paper introduces the design ideas of the monitoring subsystem from the four aspects of architecture,network,functionality,and maintenance,and verifies the feasibility and advantages of some designs through the prototype system,which can significantly benefit the construction of future exascale HPC systems.
