<div dir="ltr" data-setdir="false">I was able to compile and get this example working. However, it does not use RDMA, as far as I can tell: the endpoint types are FI_EP_MSG and there are no memory regions declared in the code. Is that correct? If so, how would I modify this example to use RDMA to send a message from one node to another?</div><div dir="ltr" data-setdir="false"><br></div><div><br></div>
