The performance utilities described in this chapter are intended to be used as a performance micro-benchmark. They support both InfiniBand and RoCE.
For further information on the following tools, please refer to the help text of the tool by running the --help command line parameter.
Utility | Description |
nd_write_bw | This test is used for performance measuring of RDMA-Write requests in Microsoft Windows Operating Systems. nd_write_bw is performance oriented for RDMA-Write with maximum throughput, and runs over Microsoft's NetworkDirect standard. The level of customizing for the user is relatively high. User may choose to run with a customized message size, customized number of iterations, or alternatively, customized test duration time. nd_write_bw runs with all message sizes from 1B to 4MB (powers of 2), message inlining, CQ moderation. |
nd_write_lat | This test is used for performance measuring of RDMA-Write requests in Microsoft Windows Operating Systems. nd_write_lat is performance oriented for RDMA-Write with minimum latency, and runs over Microsoft's NetworkDirect standard. The level of customizing for the user is relatively high. User may choose to run with a customized message size, customized number of iterations, or alternatively, customized test duration time. nd_write_lat runs with all message sizes from 1B to 4MB (powers of 2), message inlining, CQ moderation. |
nd_read_bw | This test is used for performance measuring of RDMA-Read requests in Microsoft Windows Operating Systems. nd_read_bw is performance oriented for RDMA-Read with maximum throughput, and runs over Microsoft's NetworkDirect standard. The level of customizing for the user is relatively high. User may choose to run with a customized message size, customized number of iterations, or alternatively, customized test duration time. nd_read_bw runs with all message sizes from 1B to 4MB (powers of 2), message inlining, CQ moderation. |
