NAME¶
rping - RDMA CM connection and RDMA ping-pong test.
SYNOPSIS¶
rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
[-C message_count] [-S message_size]
rping -c [-v] [-V] [-d] -a address [-p port]
[-C message_count] [-S message_size]
DESCRIPTION¶
Establishes a reliable RDMA connection between two nodes using the librdmacm,
optionally performs RDMA transfers between the nodes, then disconnects.
OPTIONS¶
- -s
- Run as the server.
- -c
- Run as the client.
- -a address
- On the server, specifies the network address to bind the
connection to. On the client, specifies the server address to connect
to.
- -p
- Port number for listening server.
- -v
- Display ping data.
- -V
- Validate ping data.
- -d
- Display debug information.
- -C message_count
- The number of messages to transfer over each connection.
(default infinite)
- -S message_size
- The size of each message transferred, in bytes. (default
100)
- -P
- Run the server in persistent mode. This allows multiple
rping clients to connect to a single server instance. The server will run
until killed.
NOTES¶
Because this test maps RDMA resources to userspace, users must ensure that they
have available system resources and permissions. See the libibverbs README
file for additional details.
