CPU-GPGPU 를 기반으로 멀티스레드 파일청킹 시스템

Abstract

The popularity of general purpose GPU（GPGPU）makes the CPU-GPGPU heterogeneous archite cture normal. Therefore, tradeoff the usage of CPU and GPGPU becomes a way to improve perfor mance of programs. In this work, we exploit the properties of the CPU-GPGPU heterogeneous arc hitecture and use them to accelerate the content based chunking operation of deduplication. We built a prototype system which is able to coordinate CPU and GPGPU to chunk file and has been proven to have a better performance compared to using either CPU or GPGPU alone.
