Detecting Soft Errors in Parallel Software with LLM-tuned Instruction Duplication

Read the original on arXiv AI →

The paper introduces PaRID, a software-directed soft error detection framework that uses parallel instruction duplication and LLM-tuned performance modeling. PaRID is designed to work at compile time for multithreaded programs, handling mixed serial and parallel regions while keeping performance overhead low. Experiments on NPB benchmarks show that PaRID cuts protection overhead from 162.79% to 59.84% on average and can achieve up to a 5× speedup while still detecting all errors.

MemTrace: Tracing and Attributing Errors in Large Language Model Memory Systems

arXiv:2605. 28732v2 Announce Type: replace-cross Abstract: Memory is essential for enabling large language models to support long-horizon reasoning, yet existing memory systems remain unreliable and difficult to debug.

Are AI Coders Snitches? An Empirical Study of Pretraining Data Detection on Code Large Language Models

The paper investigates whether code large language models (CodeLLMs) inadvertently reproduce proprietary or sensitive code by evaluating seven state‑of‑the‑art training data detection (TDD) methods on eight CodeLLMs. It introduces CodeSnitch, a benchmark of 9,000 function‑level code samples across three languages, each labeled as included or excluded from training data, and applies mutation strategies based on the Type‑1 to Type‑4 code clone taxonomy to test TDD robustness. The study offers a systematic assessment of current TDD techniques for code and suggests directions for developing more effective detection methods.

Trustworthy Runtime Error Healing in Real-World Repositories: A Benchmark and Guardrail

The paper introduces HealBench, a benchmark of 265 runtime errors from 18 real-world repositories, and HealGuard, a safety framework that restricts healing code to an analyzable subset of Python and applies static and dynamic taint analysis. Using these tools, the authors evaluate a dedicated healing method and three general coding agents powered by different LLM backbones, achieving a 38.11% resume rate and a 28.68% test‑pass rate, while HealGuard flags 17.4% of successful healings as potentially unsafe. The study demonstrates that current LLM agents can meaningfully repair real repository crashes, but also highlights significant safety concerns that the Guardrail framework can detect, albeit with a high false‑positive rate.
