interrupt

A new exploit technique breaks System Management Mode (SMM) security on x86 CPUs by using an extremely long-running single instruction to desynchronize cores, allowing an attacker to execute SMM code while another core remains outside the protected environment. A proof-of-concept for Zen 3 Ryzen processors is provided.

monday.com's Director of Engineering Dor Cohen will speak at Interrupt London about building a dual-pipeline LLM eval system using LangSmith production traces for online and offline evaluation.

A 2019 blog post argues that preemption (interrupts) can be used as a pre-paid barrier for memory ordering in lock-free programming, similar to how garbage collection is a sunk cost, and demonstrates implementations for event counts and asymmetric flag flips on Linux/x86.

Mukil Loganathan from LangChain introduced LangSmith Sandboxes at the Interrupt conference, enabling safe execution of agent code with low latency, secure isolation, persistence, and snapshot/restore capabilities.

LangChain announces on-demand interrupt capability for agents, highlighted in Harrison Chase's Day 2 keynote.
