高性能计算（HPC）应用程序历来都是在静态资源分配中执行的，使用独立于驻留系统管理堆栈（SMS）运行的编程模型。然而，要实现既具有成本效益又符合站点级环境限制的兆级性能，需要应用程序和SMS协同编排工作流，以优化资源利用率并补偿运行中的故障。过程管理接口- Exascale（PMIX）社区致力于通过定义一组抽象的接口来建立可扩展的工作流编排，通过这些接口，不仅应用程序和工具可以与驻留的SMS进行交互，而且各种SMS组件也可以相互交互。本文对PMix标准的目标和现状进行了高层次的概述，并为未来的发展方向制定了路线图。
High-Performance Computing (HPC) applications have historically executed in static resource allocations, using programming models that ran independently from the resident system management stack (SMS). Achieving exascale performance that is both cost-effective and fits within site-level environmental constraints will, however, require that the application and SMS collaboratively orchestrate the flow of work to optimize resource utilization and compensate for on-the-fly faults. The Process Management Interface - Exascale (PMIx) community is committed to establishing scalable workflow orchestration by defining an abstract set of interfaces by which not only applications and tools can interact with the resident SMS, but also the various SMS components can interact with each other. This paper presents a high-level overview of the goals and current state of the PMIx standard, and lays out a roadmap for future directions.
