Building high-performance systems with RDMA

Remote direct memory access (RDMA) has generated considerable interest in applying it in modern datacenters. Nevertheless, to fully utilize its high performance, we need designs to bridge the semantic gap between systems and RDMA's hardware features and optimizations guidelines to coordinate it with other hardware technologies (e.g., NVM).

In this talk, I will present our recent efforts in building high-performance systems with RDMA. First, I will introduce XStore, a network-attached key-value store that uses a machine learning approach to reduce the RDMA operations required for index traversal from O(log N) to O(1). Next, I will show our systematic study to efficiently coordinate RDMA and non-volatile memory (NVM) together. Finally, I will present how we provides RDMA-based primitives to accelerate serverless computing applications.
