I/o for LLM inference: a survey of storage and memory bottlenecks
Dear Ian Eslick — this week’s five most relevant discoveries, curated for your work in Artificial Intelligence.
Key findings
Computer Science · Artificial Intelligence
No. 1
This survey decomposes LLM inference I/O into three distinct flows—model weight, KV cache, and activation I/O—and applies roofline analysis to map optimizations to memory-hierarchy targets. It finds that stacking optimizations like quantization, FlashAttention, and speculative decoding causes the dominant bottleneck to oscillate between weight and KV cache I/O. For a systems and AI researcher, understanding these shifting bottlenecks is critical for designing efficient inference pipelines and silicon architectures that will power next-generation interactive AI.

Zero-shot temporal resolution domain adaptation for spiking neural networks
This paper demonstrates zero-shot adaptation of spiking neural networks across different temporal resolutions, eliminating the need for retraining when input timing characteristics change. The approach preserves spike-timing-dependent dynamics while generalizing to unseen temporal domains. For an entrepreneur with a silicon background, this advance moves neuromorphic hardware closer to practical deployment, and for AI research, it opens new techniques for efficient temporal domain adaptation.
