Optimization and Evaluation of Ceph Distributed File System on TianHe-2 Supercomputer - Li Wang, NUDT

Sign up or log in to save this to your schedule and see who's attending!

Ceph is a distributed object store and file system shipped with Linux kernel and OpenStack. In this presentation, Li Wang will give an introduction to their works on Ceph optimization and evaluation. The two features newly developed are inline data support and fallocate/punch hole support. The former speeds up the small file IO, while the latter enables sparse file support, which improves space efficiency in virtualization situation. The other two features ongoing/planning are client side transparent compression support as well as lightweight POSIX interface support based on flat namespace. In addition, Li Wang will present the detailed evaluation results of Ceph on TianHe-2 supercomputer manufactured by NUDT, which was topped the TOP500 list of fastest supercomputers in the world in June 2013. The evaluations cover throughput, scalability, and so on.
