<p class="MsoNormal">Hey,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve been trying to figure out the best way to manage job/auth keys in a libfabric provider. PSM2 appears to require the key to be passed in as an environment variable – but will override that value if one is provided in the domain or fabric
auth_key fields. (I think?)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">That said, I’m not sure how those fields are supposed to be generated. Reviewing other providers, it looks like it’s possible for a provider to generate the auth_key but I don’t see how that would be globally unique across the fabric and
the only provider that seems to do this is gni.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there something I’m missing? I know OMPI passes in something that can be used as an auth_key but I’d like to be able to support more than just OMPI.<o:p></o:p></p>
