8:30 AM Reception, Arm Lobby Reception, Arm Lobby Reception, Arm Lobby
9:00 AM Keynote: LANL, Steve Poole Keynote: Astra/Sandia UCX and MPI experience Keynote: RDMA Core Overview, Jason
10:00 AM Topic: UCX Roadmap 2019 and UCX 2.0.
Abstract: Things we would like to change/optimize/cleanup in next UCP API, and backward compatibility considerations
Speaker: Pasha/ARM and Yossi/Mellanox, 1hr.		 Topic: UCT component architecture.
