[openib-general] [PATCH] [RFC] - example user mode rdma ping/pongprogram using CMA

[Sean Hefty]

>Attached is a user-mode program, called rping, that uses librdmacm and
>libibverbs to implement a ping-pong program over an RC connection.  The
>program utilizes SEND, RECV, RDMA READ, and WRITE ops, as well as cq
>channels to get cq events, and rdma_get_event() to detect CMA events.
>It is multi-threaded.
>
>I've built it as an example program in librdmacm/examples and tested it
>with mthca.  It is useful to test CMA as well as all the major rdma
>operations in a transport-neutral way.
>
>If you all find it has utility, please pull it into librdmacm/examples.

Thanks.  I may not get a chance to test this for a couple of days, but some
additional tests for librdmacm would definitely be useful.
