A generic I/O architecture for data-intensiveapplications based on in-memorydistributed cache

Proceedings of the First PhD Symposium on Sustainable Ultrascale Computing Systems (NESUS PhD 2016) Timisoara, Romania. February 8-11, 2016.The evolution in scientific computing towards data-intensive applications and the increase of heterogeneity in the computing resources, are exposing new challenges in the I/O layer requirements. We propose a generic I/O architecture for data-intensive applications based on in-memory distributed caching. This solution leverages the evolution of network capacities and the price drop in memory to improve I/O performance for I/O-bounded applications adaptable to existing high-performance scenarios. We have showed the potential improvementsEuropean Cooperation in Science and Technology.
