Clusters in the area of high-performance computing have been growing in size at a considerable rate. In these clusters, the dominate programming model is the Message Passing Interface (MPI), so the MPI library has a key role in resource usage and performance. To obtain maximal performance, many clusters deploy a high-speed interconnect between compute nodes. One such interconnect, InfiniBand, has been gaining in popularity due to its various features including Remote Data Memory Access (RDMA), and high-performance.
