<p>I have written a libfabric provider for our hardware and it passes all the fabtests I expect it to (dgram and msg). I am trying to run some MPI tests using libfabrics under openmpi (4.0.2). When I run a simple ping-pong test using mpirun it sends and receives
the messages using the tcp/ip protocol. It does call my fi_getinfo routine, but doesn't use my provider send/receive routines. I have rebuilt the libfabric library disabling sockets, then again --disable-tcp, then --disable-udp, and fi_info reports fewer
and fewer providers until it only lists my provider, but each time I run the mpi test, it still uses the ip protocol to exchange messages.<o:p></o:p></p>
<p><o:p> </o:p></p>
<p>When I configured openmpi I specified --with-libfabric=/usr/local/ and the libfabric library is being loaded and executed.<o:p></o:p></p>
<p><o:p> </o:p></p>
<p><span style="font-size:12.0pt">I am probably doing something obviously wrong, but I don't know enough about MPI or maybe libfabric, so need some help. If this is the wrong list, redirect me.<o:p></o:p></span></p>
<p><o:p></o:p></p>
<p>Any suggestions?<o:p></o:p></p>
