<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D">Did you try running it with a stable version of libfabric (1.4.1)? Is there a reason you want to be on the tip of the master? There were a few libfabric API changes
and updates to verbs provider that might have broken the rma_bw test. I’m gonna look into it now.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-GB">I considered using endpoint type RDM, but unfortunately, RDM is not supported by verbs either, and ep MSG not working any more with GNI (I only get “connection rejected” messages when I try it), so the two providers I’m
targeting are mutually incompatible – this is making development decisions difficult.<o:p></o:p></span></p>
