I will be in 10-1:30, skipping lunch to meet my students
(and attending with them the defense).

>       demonstrated the effectiveness of the proposed architecture: the
>       prototype achieved up to two orders of magnitude higher data
>       movement rate than existing approaches. Moreover, the system
>       prototype was incorporated with features that were not well
>       supported in conventional systems, such as distributed metadata
>       management, distributed caching, lightweight provenance,
>       transparent compression, acceleration through GPU encoding, and
>       parallel serialization. Towards exploring the proposed
>       architecture at millions of node scales, simulations were
>       conducted and evaluated with a variety of workloads, showing
>       near linear scalability and orders of magnitude better
>       performance than today's state-of-the-art storage systems.
