Workload characteristics of DNA sequence analysis: from storage systems' perspective

The recent development of NGS (Next Generation Sequencing) methods has greatly increased the amount of genome data and created the need for high-performance computing and high-performance storage systems. The key issue in developing high-performance storage systems is building a storage system that is optimized for NGS analysis pipeline. In this paper, we implemented a tool to collect and analyze I/O workload in NGS analysis pipeline. Using this tool, we executed NGS analysis pipeline and analyzed the characteristics of I/Os collected in the experiment.
