Replicate What Varies: Resource Sharing for Domain-Randomized Embodied Simulation

Patchwork is a resource‑sharing system for domain‑randomized embodied simulation that separates a shared template of common resources from patches that record environment‑specific mutations. By sharing compiled model structure and immutable assets while keeping mutable parameters private, Patchwork reduces CPU memory usage dramatically—up to 92% at 32 replicas—compared to running each environment in its own process. The approach was implemented on robosuite and MuJoCo and evaluated on LIBERO‑plus and RoboCasa365 workloads, demonstrating that memory growth shifts toward template diversity rather than instance count.

SpecBox: Speculative Sandbox Scheduling for Efficient LLM Agent Serving

arXiv:2607. 23933v1 Announce Type: cross Abstract: As LLM agents increasingly rely on the Model Context Protocol (MCP) to invoke isolated external sandboxes, disaggregated sandbox deployment introduces a fundamental tension between resource utilization and interactive tail latency.

DCO: Dynamic Cache Orchestration for LLM Accelerators through Predictive Management

The paper proposes DCO, a dynamic cache orchestration scheme for multi-core AI accelerators that uses application-aware policies and dataflow information to guide cache replacement, bypass decisions, and thrashing mitigation. Using a cycle-accurate simulator, the authors demonstrate up to 1.80× speedup over conventional cache architectures and validate the approach with an analytical model and RTL implementation. The design occupies 0.064 mm² on a 15 nm process and operates at 2 GHz, showing that a shared system-level cache can simplify programming while boosting performance for large language model workloads.
