Cooperative Preprocessing at Petabytes on High Performance Computing System

Abstract

With the explosion of data, we have an urgent demand for data throughput in high performance computing systems. Data-intensive applications are becoming increasingly common in HPC environments. As data scale increases faster than systems, it’s time to fully utilize resources in every aspect, including computing power, storage capacity and data throughput. We can no longer ignore data preprocessing since it’s an important procedure, especially when dealing with large amount of data. How to efficiently perform data preprocessing in current HPC systems? How to make full use of system resources on data-intensive applications? What should be valued when designing new HPC architectures? All these questions need answers. In this paper, we drew a sketch for procedure of data-intensive applications, which lead to an adaptive resource allocation scheme according to procedure requirements. We analyzed characters of preprocessing and designed a preprocessing model for data-intensive applications in HPC systems. It has not only fulfilled the demand for computing but also meet the need of throughput, with cooperative work in storage system and storage management system. Experiments were done on Sunway TaihuLight, one of the world’s fastest supercomputers. The whole procedure of preprocessing at Petabytes can be done in hours without interfering other ongoing applications.
