Resuming Vision-Language Inference across Onboard Interruptions

OrbitWeaver is a framework that enables vision‑language models to resume inference after onboard interruptions on low‑Earth orbit satellites. It uses phase‑aware checkpointing and dependency‑aware dynamic recovery to preserve progress across power, thermal, and fault‑induced shutdowns, reducing restart latency and SSD write volume. Experiments on satellite payload hardware show up to a 4.07‑fold speedup and a 3.56‑fold reduction in write traffic, and a 72‑hour deployment confirmed its ability to maintain inference progress across repeated bus‑enforced shutdowns.

Concordia: JIT-Compiled Persistent-Kernel Checkpointing for Fault-Tolerant LLM Inference

Long-running LLM agents keep valuable state resident on GPUs: KV caches, request schedulers, communication state, and sometimes online adapters. Losing this state after a GPU or communicator failure can discard minutes to hours of work, yet existing recovery mechanisms either restart the whole serving stack or require application-specific checkpoint logic inside every attention and runtime component.

Zephon: Elastic Determinism for Online, Stateful Foundation Model Data Loading Pipelines

Zephon is a data loader designed for foundation model training that ensures deterministic ordering of training data batches even when GPU resources change, checkpoints are resumed, or different processing backends are used. It handles online, stateful pipelines—where tokenization, packing, and mixing of samples create complex n‑to‑m transformations—by partitioning the data stream into topology‑independent lanes, serializing ordering decisions, and checkpointing only bounded in‑flight state. Experiments on text and vision‑language tasks show Zephon delivers competitive throughput while offering guarantees that existing loaders lack for such pipelines.
