AdaFuse: Adaptive Function Fusion for Dynamic Serverless Workflows

A new adaptive function fusion strategy that dynamically reconstructs serverless workflows by adjusting communication schemes between functions in response to changing workflow invocations is proposed, which jointly optimizes function fusion and instance reconfiguration through an efficient beam-search–based algorithm...

MIGServe: Layout-Aware Multi-Instance GPU Management for Efficient LLM Serving

MIGServe treats the physical layout of MIG instances as a first-class scheduling dimension through three techniques: buddy-aware partition placement, which preserves large contiguous free blocks by allocating next to existing occupied buddies; proactive pair-matching migration, which consolidates fragmented half-full b...

FairCache: Demystifying Cache-Induced Unfairness in Multi-Tenant Large Language Model Serving

Large language models (LLMs) increasingly rely on context caching to enhance serving efficiency. However, this optimization inadvertently compromises fairness in multi-tenant LLM serving systems. Existing fair schedulers, which account only for compute resources, are unable to handle the multi-dimensional resource dema...
