1.Benchmarking GPUDirect RDMA on Modern Server Platforms (2014)

• As we are interested in the low-level performance of our platforms, we used three IB Verbs-level benchmark programs. For latency we used ibv_ud_pingpong from libibverbs-1.1.7, while for bandwidth we adopted ib_rdma_bw from perftest-1.3.0. The former uses the IBV_WR_SEND primitive and the UD protocol; the latter the IBV_WR_RDMA_WRITE primitive and the RC protocol. Those test programs have been properly modified both to target GPU memory and take advantage of GPUDirect RDMA. We also employed a modified version of ib_write_bw, out of perfest-2.0, to exploit the full peak performance of the PCIe x16 Gen3 link on the Connect-IB HCA. The end of this post gives the details of the hardware platforms and the software we used.
