高性能计算（HPC）硬件/软件协同设计的一个新兴方面是研究故障下的性能。本文的工作扩展了极限规模模拟器（xSim），这是专为评估性能的消息传递接口（MPI）应用程序在未来的HPC架构，与容错MPI扩展提出的MPI容错工作组。xSim允许运行具有数百万个并发MPI队列的MPI应用程序，同时使用轻量级并行离散事件模拟在模拟的极端规模系统中观察应用程序性能。新添加的功能在模拟MPI层提供用户级故障缓解（ULFM）扩展，以支持基于算法的容错（ABFT）。所提出的解决方案允许调查ABFT解决方案的故障和故障处理下的性能。新增强的xSim是第一个支持ULFM和ABFT的性能工具。
An emerging aspect of high-performance computing (HPC) hardware/software co-design is investigating performance under failure. The work in this paper extends the Extreme-scale Simulator (xSim), which was designed for evaluating the performance of message passing interface (MPI) applications on future HPC architectures, with fault-tolerant MPI extensions proposed by the MPI Fault Tolerance Working Group. xSim permits running MPI applications with millions of concurrent MPI ranks, while observing application performance in a simulated extreme-scale system using a lightweight parallel discrete event simulation. The newly added features offer user-level failure mitigation (ULFM) extensions at the simulated MPI layer to support algorithm-based fault tolerance (ABFT). The presented solution permits investigating performance under failure and failure handling of ABFT solutions. The newly enhanced xSim is the very first performance tool that supports ULFM and ABFT.
