在支持HPC的性能、可移植性和生产力方面取得了长足的进步,但到目前为止,重点一直放在独立的应用程序和节点编程模型上。由许多通信协调器、服务和模拟组成的复杂工作流正在重新定义现代HPC应用程序的外观,现在是时候重新审视在工作流级考虑时性能、可移植性和性能意味着什么了。哪些定义对工作流最有意义?如何使用不兼容的软件跨HPC中心部署工作流?我们如何确保不只是一个而是多个应用程序以优化的方式在不同的集群中可靠地部署?这篇文章强调了趋势,揭示了新的挑战,并指出了一些潜在的解决方案。
Great strides have been made to enable performance, portability, and productivity in HPC, but the focus has so far been on standalone applications and on-node programming models. Complex workflows comprising many communicating orchestrators, services, and simulations are redefining what modern HPC applications look like, and it is time to revisit what performance, portability, and performance mean when considered at the workflow level. What definitions make the most sense for workflows? How can workflows be deployed across HPC centers with incompatible software? And how can we ensure that not just one but many applications are deployed reliably and in an optimized way across different clusters? This paper highlights trends, reveals new challenges, and points to some potential solutions.
