RDMA-based Communications

High-performance network hardware is nowadays dominated by RDMA-oriented technologies. The software stack is moving too towards Remote Memory Access. However, most communication libraries stil use send/receive paradigm as a common denominator. We have proposed to study a software stack for networks the is based on remote memory access from the hardware up to the enduser API, where RDMA is first class citizen and not a compatibility layer. It is expected to obtain better performance, better scalability with regard to number of communication flows or threads, and better asynchronous progression, while optimization strategies on the packet flows such as aggregation as proposed in NewMadeleine are still possible. Work has begun as a Masters thesis [18] and continues as Romain Prou Ph.D. thesis.
