rping - RDMA CM connection and RDMA ping-pong test.

NAME SYNOPSIS DESCRIPTION OPTIONS NOTES SEE ALSO

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] [-I address] -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. To bind to any address with IPv6 use -a ::0 . On the client, specifies the server address to connect to.

−I address

The address to bind to as the source IP address to use. This is useful if you have multiple addresses on the same network or complex routing.

	−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.
	−q		Control QP Creation/Modification directly from the application, instead of rdma_cm.

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.
