I notice in your pasted input below ibv_rc_pingpong you include the argument '-g 0'. If you have not already, please try running the tests with '-g 1' on both machines.
You should be able list all of the GID entries with cat /sys/class/infiniband/rxe0/ports/1/gids/*
. The first entry (number 0) is the link local GID only; entry 1 should be used for testing purposes.
The ibv_read_bw
test may benefit from adding the '-R' flag. This will attempt to connect using rdma_cm instead of the default Ethernet approach.
I followed instruction from https://github.com/SoftRoCE/rxe-dev/wiki/rxe-dev:-Home to configure and install SoftROCE, rping and ibv_write_bw works but no response for ibv_rc_pingpong and ibv_read_bw.
How to troubleshoot this issue?
