AsymFlow: Enabling Long-Context LLM Serving via CPU-GPU Prefill-Decode Disaggregation

Driven by cost and privacy constraints, many organizations deploy large language model (LLM) inference on local CPU-GPU servers. For long-context requests, the key-value (KV) cache grows linearly with sequence length and can rapidly exhaust GPU memory, reducing both the maximum supported context and request concurrency...

LEO: Enabling Efficient Communication-Computation Pipeline for GNN via Hierarchical Caching

Training large-scale graphs with GNNs on multi-GPU platforms faces substantial feature loading overhead, leading to low resource utilization and inefficient training. Overcoming such communication bottlenecks is crucial, and current solutions achieve this by overlapping computation and communication through pipelining....
