This paper presents ZCube, a novel network architecture developed by Z.ai, Harnets.AI, and Tsinghua University to address topology-induced congestion in Prefill-Decode disaggregated LLM inference clusters. Production deployments on GLM-5.1 coding workloads achieved a 33% reduction in network CapEx, 15% throughput improvement, and 40.6% reduction in TTFT P99 latency.
Show HN: misa77 - a codec that decodes 2x faster than LZ4 (at better ratios)
misa77 is a new LZ-based codec that achieves decompression throughput up to 2x faster than LZ4 while also offering better compression ratios. It targets write-once read-many workloads and has constant memory usage.
@tom_doerr: Compresses deep learning models for faster inference https://github.com/NVIDIA/Model-Optimizer…
NVIDIA Model Optimizer is a library that compresses deep learning models using techniques like quantization, distillation, pruning, and speculative decoding to accelerate inference. It supports Hugging Face, PyTorch, and ONNX models and integrates with NVIDIA inference frameworks.
ELMZip: Onboard Satellite Image Compression via Extreme Learning Machines for Efficient Downlink
ELMZip is a novel satellite image compression framework using Extreme Learning Machines (ELM) and domain decomposition to enable efficient onboard neural representation, transmitting only compact output weights to reduce downlink payload while maintaining high reconstruction fidelity.
@MaxForAI: http://Z.ai and this ZCube paper from Tsinghua—worth a read for anyone in Infra. Many people's first reaction when talking about AI infra is still GPU, memory, quantization, and inference frameworks. But once you get into long context and Prefill-Decode separation, the network is no longer just a 'supporting role' in the data center. Every...
ZCube is a new network architecture that flattens the topology and mixes single/multi-rail access to optimize KV Cache transmission in long-context and PD separation scenarios. In the GLM-5.1 production cluster, it achieved a 33% reduction in switch/optical module costs, a 15% increase in GPU inference throughput, and a 40.6% decrease in TTFT P99.
