Имя (Name)
rping - RDMA CM connection and RDMA ping-pong test.
Синопсис (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]
Описание (Description)
Establishes a reliable RDMA connection between two nodes using
the librdmacm, optionally performs RDMA transfers between the
nodes, then disconnects.
Параметры (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.
Примечание (Note)
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.
