InfiniBand/RoCE RDMA Specification Update

The first phase of the IBTA Memory Placement Extensions (MPE), supporting low-latency RDMA access to persistent memory on Infiniband and RoCE networks, was published in August. In this talk, the MPE will be introduced, motivations for the additions discussed, and performance advantages of the MPE over current techniques will be reviewed. In addition to the these new MPE protocol enhancements in the new specification, additional operations, currently under development and planned for the next version, will also be presented.

• Understand what the MPE are
• Understand how the MPE can improve existing techniques
• Understand scenarios where MPE may be beneficial
