CMTIME(1) librdmacm CMTIME(1) NAME cmtime - sample program that times rdma cm calls SYNOPSIS cmtime [-s server_address] [-b bind_address] [-c connections] [-p port_number] [-t timeout_ms] cmtime -s server_address [-b bind_address] [-c connections] [-p port_number] [-t timeout_ms] DESCRIPTION Measures how long it takes for each step in the RDMA connection process to complete. It can be used to analyze the performance of the various CM steps. OPTIONS -s server_address The IP address of the server system listening for connections. The used address must route over an RDMA device.This option must be specified by the client. -b bind_address The local network address to bind to. -c connections The number of connections to establish between the client and server. (default 100) -p port_number Specifies the port number that the server listens on. By default the server listens on port 7471. -t timeout_ms Specifies the timeout value in milliseconds for which it would try to resolve the given IP address. By default, the value is 2000ms ATTRIBUTES See attributes(5) for descriptions of the following attributes: +---------------+-----------------------+ |ATTRIBUTE TYPE | ATTRIBUTE VALUE | +---------------+-----------------------+ |Availability | network/open-fabrics | +---------------+-----------------------+ |Stability | Pass-through volatile | +---------------+-----------------------+ NOTES Basic usage is to start cmtime on a server system, then run cmtime -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.
