High performance interconnects such as InfiniBand (IB) have enabled large scale deployments of High Performance Computing (HPC) systems. High performance communication and IO middleware such as MPI and NFS over RDMA have also been redesigned to leverage the performance of these modern interconnects. With the advent of long haul InfiniBand (IB WAN), IB applications now have inter-cluster reaches. While this technology is intended to enable high performance network connectivity across WAN links, it is important to study and characterize the actual performance that the existing IB middleware achieve in these emerging IB WAN scenarios.
