Achievements and challenges for I/O in computational science
Robert B. Ross, Rajeev Thakur, Alok Choudhary · Journal of Physics Conference Series · 2005
The data access needs of computational science applications continue to grow, both in terms of the rates of I/O necessary to match compute capabilities, and in terms of the features required of I/O systems. Particularly, wide-area access to data, and moving data between systems, has become a priority. Key achievements in I/O for computational science have enabled many applications to effectively use I/O resources. However, growing application requirements challenge I/O system developers to create solutions that will make I/O systems easier to use, improve performance, and increase the manageability. In this work we outline the recent achievements and current status of I/O systems for computational science. We then enumerate key challenges for I/O systems in the near future and discuss ongoing efforts that address these challenges.
