<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">There are two ways to use RDM endpoint in verbs provider: one is the verbs/RDM path that’s internal to the provider and the other is through the ofi_rxm utility provider which layers on top of verbs provider.
The former would be deprecated from libfabric 1.7 onwards and it’s advisable to use ofi_rxm.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">To use the internal verbs/RDM path, FI_CONTEXT mode bit needs to be set in hints. To use ofi_rxm FI_MR_LOCAL domain attribute mr_mode bit needs to be set.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Can you try with the following added to your code:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">hints->domain_attr->mr_mode = FI_MR_LOCAL;<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">hints->mode = FI_CONTEXT;<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Note: Passing FI_LOCAL_MR in hints->mode as you have in the code should have worked for ofi_rxm but there is a bug which currently prevents that. It should be fixed in the next release.<o:p></o:p></span></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am trying to work with Libfabric in our cluster but currently facing some issues. While checking the ‘fi_info’ with the provider as ‘verbs’, I am getting verbs provider for the current node.<o:p></o:p></p>
