High-performance computing systems have already approached peta-scale with hundreds of thousands of processors/cores in many deployments. These systems promise a new level of predictive and knowledge discovery ability as researchers gain the capability to model dependencies between phenomena at scales not seen earlier. These applications are highly I/O and data intensive, leading scientists to observe that performing I/O and subsequent analyses are major bottlenecks in effectively utilizing peta-scale systems and a major hurdle in accelerating discoveries. Although significant progress has been made in performance, interfaces, and middleware runtime systems for I/O in the recent past, significantly more research and development needs to be carried out to scale the performance to the desired levels for systems containing tens to hundreds of thousands of cores. In this work we outline our recent achievements and current research for designing scalable I/O software and enabling data analytics in storage systems. We also enumerate key challenges for the I/O systems and discuss ongoing efforts that address these challenges.
