HPC Application Parameter Autotuning on Edge Devices: A Bandit Learning Approach
This addresses the problem of efficient HPC parameter tuning for edge computing, though it appears incremental as it adapts existing bandit methods to a specific domain.
The paper tackles the challenge of optimizing HPC application parameters on resource-constrained edge devices by introducing LASP, a lightweight autotuning strategy using a multi-armed bandit approach, which achieved significant performance improvements in tests with applications like Lulesh and Kripke.
The growing necessity for enhanced processing capabilities in edge devices with limited resources has led us to develop effective methods for improving high-performance computing (HPC) applications. In this paper, we introduce LASP (Lightweight Autotuning of Scientific Application Parameters), a novel strategy designed to address the parameter search space challenge in edge devices. Our strategy employs a multi-armed bandit (MAB) technique focused on online exploration and exploitation. Notably, LASP takes a dynamic approach, adapting seamlessly to changing environments. We tested LASP with four HPC applications: Lulesh, Kripke, Clomp, and Hypre. Its lightweight nature makes it particularly well-suited for resource-constrained edge devices. By employing the MAB framework to efficiently navigate the search space, we achieved significant performance improvements while adhering to the stringent computational limits of edge devices. Our experimental results demonstrate the effectiveness of LASP in optimizing parameter search on edge devices.
