As the scale and complexity of parallel systems continue to grow, failures are inevitable. For years research focused on pre-failure prediction and tolerance - predicting failures and taking precautionary actions before failure occurrence. Despite progress on failure prediction, unexpected failures occur in practice, especially in modern systems with unprecedented sizes and complexities. Relying on pre-failure prediction and tolerance alone is insufficient for fault management because of the inevitability of failures. Just as failures need to be carefully avoided and managed when they occur, post-failure diagnosis and recovery is of equal importance and has a profound impact on almost every aspect of parallel computing. The goal of this research project is to develop RAPS, a Recovery Aware Parallel computing System for post-failure diagnosis and recovery. The research focuses on how to quickly and effectively resume parallel computing after a failure has occurred. The ultimate goal is to seamlessly integrate post-failure diagnosis and recovery with pre-failure prediction and tolerance as a compound fault management solution for parallel computing. The approach consists of (1) development of new diagnosis mechanisms for fast failure detection and root cause analysis, (2) development of system-wide orchestration for recovery coordination, (3) design of new recovery techniques for quick restoration of parallel applications, and (4) a comprehensive evaluation. The results of this project can significantly improve the productivity of parallel systems. This project also enhances the CS curriculum at IIT and broadens the participation by underrepresented groups.

随着并行系统的规模和复杂性不断增长，故障是不可避免的。 多年来，研究重点是故障前预测和容忍度——预测故障并在故障发生前采取预防措施。尽管在故障预测方面取得了进展，但实践中还是会发生意外故障，特别是在规模和复杂性前所未有的现代系统中。由于故障是不可避免的，仅依靠故障前的预测和容错来进行故障管理是不够的。 正如故障发生时需要小心避免和管理一样，故障后诊断和恢复也同样重要，并且对并行计算的几乎每个方面都有深远的影响。 该研究项目的目标是开发 RAPS，一种用于故障后诊断和恢复的恢复感知并行计算系统。研究重点是发生故障后如何快速有效地恢复并行计算。最终目标是将故障后诊断和恢复与故障前预测和容忍无缝集成，作为并行计算的复合故障管理解决方案。该方法包括（1）开发用于快速故障检测和根本原因分析的新诊断机制，（2）开发用于恢复协调的系统范围编排，（3）设计用于快速恢复并行应用程序的新恢复技术，以及(4)综合评价。该项目的成果可以显着提高并行系统的生产率。该项目还增强了印度理工学院的计算机科学课程，并扩大了代表性不足群体的参与。
