Adaptive Scheduling of Multimodal Large Language Model in Intelligent Edge Computing
Multimodal Large Language Models (MLLMs) integrate multimodal encoders with Large Language Models (LLMs) to overcome the limitations of text-only models. Traditional LLMs are deployed on high-performance cloud servers, but MLLMs, which process multimodal data, face high transmission latency and privacy risks when tasks are offloaded to the cloud. Intelligent edge computing is a promising solution for supporting such latency-sensitive and privacy-sensitive tasks. However, the heterogeneity of edge environments makes efficient MLLM inference challenging. In this work, we enhance MLLM inference efficiency in heterogeneous edge environments by decoupling MLLM into LLM and multimodal encoders, deploying the LLM on high-performance devices and the multimodal encoders on lower-capability devices. Additionally, we observe that processing MLLM tasks in edge environments involves numerous configuration parameters that impact inference speed and energy consumption in an unknown and possibly time-varying fashion. To address this challenge, we present an adaptive scheduling algorithm that assigns parameters to tasks or minimizing energy consumption while meeting maximum latency constraints. The results of extensive experimental trials demonstrate that the proposed approach consistently outperforms existing state-of-the-art methods, achieving significant improvements in both latency reduction and energy efficiency.

Decoupled MLLM Architecture for Edge Environments
This research proposes a novel decoupling of Multimodal Large Language Models (MLLMs) to optimize inference in resource-constrained edge environments. By separating the computationally intensive LLM component from the multimodal encoders, the system can leverage heterogeneous edge devices more effectively.
Key Insight: Offloading multimodal encoding to lower-capability edge devices (like those with DLAs) reduces transmission latency and balances computational load, while high-performance devices handle LLM inference. This hybrid approach significantly improves overall system latency and energy efficiency.
Heterogeneity & Resource Constraints at the Edge
Intelligent edge computing offers a promising solution for latency-sensitive and privacy-sensitive MLLM tasks by bringing computation closer to data sources. However, edge environments are characterized by their inherent heterogeneity in computational capabilities and variable resource availability.
Key Insight: Traditional LLM deployment on cloud servers is inefficient for multimodal data due to high transmission latency and privacy concerns. At the edge, managing MLLM tasks is challenging due to the diverse capabilities of edge devices and the unpredictable interplay between hardware, power, and load conditions affecting performance and energy consumption.
Bayesian Adaptive Scheduling Algorithm
To address the dynamic and unpredictable nature of MLLM task execution in heterogeneous edge environments, the paper introduces an adaptive scheduling algorithm based on the Multi-Armed Bandit (MAB) problem, enhanced with Gaussian Processes (GPs) and safety constraints.
Key Insight: The algorithm intelligently selects the optimal configuration (component, power level, and load) for multimodal encoding tasks. It learns from real-time feedback to minimize energy consumption while strictly adhering to user-defined latency constraints, ensuring both efficiency and reliability even with noisy and non-monotonic system behavior.
Superior Performance & Energy Efficiency
Extensive experimental trials and simulations demonstrate the proposed algorithm's significant advantages over existing state-of-the-art MAB methods in terms of energy consumption and latency reduction.
Key Insight: The GP-UCB based adaptive scheduler consistently achieves lower total energy consumption and higher precision in safe set identification. It intelligently balances exploration and exploitation, leading to optimal configurations that not only meet strict latency requirements but also result in substantial energy savings, particularly in high-power scenarios.

Case Study: Navigating Unpredictable Edge Device Behavior
The research reveals that the interplay between an edge device's computing component (GPU, CPU, DLA), its power setting (e.g., 15W, 30W, MAXN), and its concurrent load condition exerts complex, often counterintuitive, effects on processing time and energy cost for multimodal encoding tasks.
For example, selecting a higher-power mode does not always guarantee lower latency, and favoring the GPU over the DLA can either save or waste energy depending on the momentary workload. A critical finding highlights that at 15W power and 20% GPU load, a single task requires 0.13 seconds and 3.2 joules. In contrast, the same task on the DLA at 30W consumes the same 3.2 joules but completes in just 0.11 seconds.
This unpredictability makes traditional static scheduling ineffective. Our adaptive scheduling algorithm directly addresses this by learning optimal configurations in real-time, ensuring resources are utilized efficiently and tasks meet their constraints in dynamic edge environments.
