KREX: Concurrent Kernel Benchmarking on Shared GPUs via Region-Granular Exclusivity

LLM agents automate GPU kernel optimization by repeatedly composing candidates and measuring their duration on real GPUs. Existing systems preserve measurement fidelity by reserving a GPU for an entire agent session or benchmarking command. However, this results in poor utilization because only a small fraction of comm...

W EAVE : Efficient Co-Scheduling for Disaggregated RL Post-Training

W EAVE is a cluster scheduling framework built on the insight that the structural idleness of one job can be effectively utilized by the active phase of another, and introduces the co-execution group abstraction, which partitions the cluster into isolated locality domains.
