RDMA: Scaling the I/O Architecture for Future Applications

SESSION: RDMA: Scaling the I/O Architecture for Future Applications


TIME: 1:30PM - 3:00PM


Panelists:Paul Grun, Sudip Dosanjh, Rick Stevens, Gary Grider


The goal for this panel is to bridge the gap between users of large scale machines and the providers of I/O architectures on which they are built. RDMA has been a dominant technology in the evolution of HPC, but since its introduction in 2000 there have been significant changes in the underlying compute model, how those machines are deployed and the ways in which they are used is producing a growing mismatch between user programs and the I/O model. To reach exascale, we have to re-think how I/O is architected. For example, are there opportunities to: - Improve the scalability and reduce the power consumption of data movement to meet exascale requirements? - Improve performance allowing researchers to solve ever-larger problems? - Take advantage of co-processing, multi-core, emerging trends toward large scale solid state devices and other technologies? - Better align I/O systems with important models like distributed shared memory?
