ucmatose - RDMA CM connection and simple ping-pong test.
ucmatose [-s server_address] [-b bind_address] [-c connections]
[-C message_count] [-S message_size]
ucmatose -s server_address [-b bind_address] [-c connections]
[-C message_count] [-S message_size] [-t tos]
Establishes a set of reliable RDMA connections between two nodes using
the librdmacm, optionally transfers data between the nodes, then
The network name or IP address of the server system listening
for connections. The used name or address must route over an
RDMA device. This option must be specified by the client.
The local network address to bind to.
The number of connections to establish between the client and
server. (default 1)
The number of messages to transfer over each connection.
The size of each message transferred, in bytes. (default 100)
-t tos Indicates the type of service used for the communication. Type
of service is implementation dependent based on subnet
-m Tests event channel migration. Migrates all communication
identifiers to a different event channel for disconnect events.
Basic usage is to start ucmatose on a server system, then run ucmatose
-s server_name on a client system.
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.
