The btl/uct code can be quite aggressive at sends connection messages over the connection endpoint. This could lead to a large number of unnecessary messages in some cases. This commit adds code to restrict the retry rate to 2ms. This timing is controlled by a new MCA variable: btl_uct_connection_retry_timeout. Signed-off-by: Nathan Hjelm <[email protected]>
