<p class="MsoNormal">>Woody asked about extensions to verbs that might work on specific technologies. Liran answered that that motivation is to >support all RDMA technologies.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Specifically, my suggestion was that if at all possible, verbs extensions should be implemented so that they can run<br>
over all underlying fabric technologies, InfiniBand, Roce, and iWarp so that ULP developers can implement
<br>
one piece of S/W that runs over all vendor’s H/W.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And if an extension is not totally generic, there needs to be an easy way for developer’s to determine if the extension<br>
is Transport specific (i.e., only works on InfiniBand and not iWarp or Roce), or vendor specific (i.e., only works on one vendor’s
<br>
proprietary H/W.)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This would help make developer’s lives easier. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My 2 cents,<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We had the first meeting of the OFVWG this morning. The call was well-attended - participates that I was able to capture: Intel, ORNL, Mellanox, Oracle, HP, Chelsio, LANL, and OSU<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Liran and Pasha volunteered to lead the first discussion at the meeting<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Gilad described the mission of the working group to enhance the verbs interface to HPC, GPUs, storage, etc. applications. Add new functionality to provide further capabilities. OFVWG is a place for discussing issues and to seek for solutions<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Liran reviewed the verbs eco-system, middleware, and described multiple examples of applications that use the verbs interface, as well examples of new capabilities that can be reviewed as options to be added to the verbs interface.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Liran reviewed new areas where the verbs can provide support for new applications (e.g. containers)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Pasha explained the OFVWG can be a place for discussing new requests of ideas related to RDMA technologies.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Pasha explained that the group can also provide support for verbs usage and implementations<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Pasha explained that one of the goals is to work with other groups and have a collaborative work around the verbs interface. Increase community awareness.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Liran gave an example on how the group can help on new areas, for example to add RDMA support for containers. Turned out there are more vendors / users that are interested in the same solution – and as the solution is non vendor specific
but apply to all RDMA technologies, this is something that can be discussed at the working group, which will enable to create a full solution for verbs, faster and easier.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Pasha explained that OFVWG can be a platform for discussions and collaborations, inside OFA but also with communities outside OFA<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Jim talked on the OFA workshop and asked if OFVWG should have a presentation in both Dev and User workshop<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There was a discussion on the user day, and positive view on presenting some of the verbs capabilities in that day.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Jim asked about IBTA. Pasha commented that OFVWG want to work with other communities and since the verbs interface is part of the IBTA standard, future development might be added to the specification, pending IBTA decision.
<o:p></o:p></p>

<p class="MsoNormal">Woody asked about extensions to verbs that might work on specific technologies. Liran answered that that motivation is to support all RDMA technologies.
