Towards Less Operating System Noise: An Approach with Data Processing Unit

High performance computing (HPC) cloud, which is a fusion of HPC and cloud, is receiving much attention due to growing demand for large-scale computing. The HPC cloud is targeted for running HPC-derived applications, but it requires solving an HPC-specific challenge, namely operating system (OS) noise. Herein, we focus on the OS noise caused by asynchronous I/O processing and propose offloading it to data processing unit (DPU).
