PFAgent: A Tractable and Self-Evolving Power-Flow Agent for Interactive Grid Analysis
Buxin She, Brian Chen, Luanzheng Guo +1
Power system simulation workflows remain expert-intensive. Engineers must translate study intents into code or API calls, execute analyses, and interpret outputs. To automate this…
QoSFlow: Ensuring Service Quality of Distributed Workflows Using Interpretable Sensitivity Models
Md Hasanur Rashid, Jesun Firoz, Nathan R. Tallent +3
With the increasing importance of distributed scientific workflows, there is a critical need to ensure Quality of Service (QoS) constraints, such as minimizing time or limiting exe…
LLMTailor: A Layer-wise Tailoring Tool for Efficient Checkpointing of Large Language Models
Minqiu Sun, Xin Huang, Luanzheng Guo +3
Checkpointing is essential for fault tolerance in training large language models (LLMs). However, existing methods, regardless of their I/O strategies, periodically store the entir…
Scrutinizing Variables for Checkpoint Using Automatic Differentiation
Xin Huang, Weiping Zhang, Shiman Meng +4
Checkpoint/Restart (C/R) saves the running state of the programs periodically, which consumes considerable system resources. We observe that not every piece of data is involved in…
Distributed Order Recording Techniques for Efficient Record-and-Replay of Multi-threaded Programs
Xiang Fu, Shiman Meng, Weiping Zhang +6
After all these years and all these other shared memory programming frameworks, OpenMP is still the most popular one. However, its greater levels of non-deterministic execution mak…
AutoCheck: Automatically Identifying Variables for Checkpointing by Data Dependency Analysis
Xiang Fu, Weiping Zhang, Xin Huang +4
Checkpoint/Restart (C/R) has been widely deployed in numerous HPC systems, Clouds, and industrial data centers, which are typically operated by system engineers. Nevertheless, ther…
