This document updates RFC 5043 and RFC 5044 by extending Marker Protocol Data Unit (PDU) Aligned Framing (MPA) negotiation for Remote Direct Memory Access (RDMA) connection establishment. The first enhancement extends RFC 5044, enabling peer-to-peer connection establishment over MPA / Transmission Co...
In tests like ib_send_bw, use -R option to select rdma_cm for connection establishment. You can also use gid-index with -x option instead of -R: Example: On Intel Ethernet 800 Series or X722: ib_send_bw -F -n 5 -x 0 ...

Let’s start by looking at the server. The connection-establishment details are now hidden behindrc_init(), which sets various callback functions, andrc_server_loop(), which runs an event loop: intmain(intargc,char**argv) { rc_init( ...
1) Use the CM libraries (libibcm/librdmacm) for connection establishment and teardown 2) Handle this within your application: maintain a "keep alive" messages and/or "leaving" message The question, is do you really need several QPs?
Typically, under network and RDMA programming, there are operations which involve interaction with remote peers (such as address resolution and connection establishment) and remote entities (such as route resolution and joining a multicast group under IB), where a resource managed through IB verbs suc...
