1. udaddy
This script covers RDMA_CM UD connections. (It establishes a set of unreliable RDMA datagram communication paths between two nodes using the librdmacm, optionally transfers datagrams between the nodes, then tears down the communication)
Run the following command on one server (act as a server):

#udaddy

Run the following command on the second server (act as a client)
# udaddy -s 12.12.12.1

udaddy: starting client
udaddy: connecting
initiating data transfers
receiving data transfers
data transfers complete
test complete
return status 0

"return status=0" means good exit (RDMA is running).

2. rdma_server, rdma_client commands
Another options is to use rdma_server and rdma_client commands:
Those commands  are simple RDMA CM connection and ping-pong test (It uses synchronous librdmam calls to establish an RDMA connections between two nodes).

Run the following command on one server (act as a server):
#rdma_server
 

Run the following command on the second server (act as a client)
rdma_client -s 12.12.12.1
rdma_client: start
rdma_client: end 0
 
"rdma_client: end 0" means good exit (RDMA is running).

3. ib_send_bw (performance test)
Run pefformance test such as ib_send_bw, ib_read_bw or similar
For Example:
Run the following command on one server (act as a server):

# ib_send_bw -d mlx4_0 -i 1 -F --report_gbits
Run the following command on the second server (act as a client):
# ib_send_bw -d mlx4_0 -i 1 -F --report_gbits 12.12.12.1

4. rping
This script covers RDMA_CM RC connections, but only userspace (It establishes a set of reliable RDMA connections between two nodes using the librdmacm, optionally transfers data between the nodes, then disconnects).
Run the following on one of the servers (act as a rping server)

# rping -s  -C 10 -v

Run the following on one of the servers (act as a rping client)
# rping  -c -a 12.12.12.1  -C 10 -v

5. ucmatose
This script covers RDMA_CM RC connections, but only userspace (same as rping) (It establishes a set of reliable RDMA connections between two nodes using the librdmacm, optionally transfers data between the nodes, then disconnects).
 

Run the following on one of the servers (act as a server)

# ucmatose
 

Run the following on the other server (act as a client)

#ucmatose -s 12.12.12.1

cmatose: starting client

cmatose: connecting

receiving data transfers

sending replies

data transfers complete

test complete

return status 0
