   Hi @hongbilu,

   You can use gds_kernel_loopback_latency, which uses one GPU and one NIC to emulate both server and client.

   Another option is to mpirun -n 2 <your-script>. Then, the script determines if it is process 0 or 1. The script then launches ./gds_kernel_latency -d <mlx5_0 or mlx5_1> -G <0 or 1>. This option is more complex but will allow you to use 2 GPUs and 2 NICs.
