TurboBus: Pooling PCIe Bandwidth for LLM Workloads via Scale-Up Fabrics

TurboBus is presented, which pools PCIe bandwidth across co-located jobs via emerging scale-up fabrics and reduces first-token latency by up to 40% for on-demand model loading, achieves up to 1.6x throughput for KV-cache-offloaded inference, and accelerates training by up to 7%, while imposing less than 1% overhead on co-located workloads.

WiCi: Wireless GPU Computing Infrastructure

The proposed Wireless GPU Computing Infrastructure (WiCi) can reduce time to first token by up to 90%, improve the token rate by approximately 39x compared to local inference on mobile devices for the same model, and support much larger models.
