<p class="MsoNormal">Another approach is the ‘cluster on a laptop’ that I described. That one uses KVM and standard enet virtual switches to create a ‘cluster in a box’.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In either case, Doug’s point was that the OFA is in a position to make it easier for people to get exposed to RDMA in a harmless and zero cost way. I think that’s something in which the OFA should invest. Fastest way I can imagine to
accelerate the adoption of high performance networks.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is not exactly true. With OFI, it supports RDMA and we have a sockets provider that people can use with any off the shelf Ethernet NIC to experiment and learn about RDMA.<o:p></o:p></p>
<p class="MsoNormal">In fact, we have a lot of development internally that uses the OFI sockets provider for initial development and then later test and tune it on hardware accelerated RDMA NICs.<o:p></o:p></p>

<p class="MsoBodyText"><span style="font-size:11.0pt">Rather, Gilad asserted that OpenRDMA doesn’t compete with the OFA because it is not doing new development. This is incorrect because the OFA’s mission is not limited to development. Our mission is to accelerate
the development <i>and adoption</i> of (e.g. RDMA). No good argument was offered for why OpenRDMA should not be hosted by the OFA under the auspices of the existing OFVWG (which was originally requested by MLNX and is currently chaired by MLNX).<o:p></o:p></span></p>

<p class="MsoBodyText"><span style="font-size:11.0pt">The OFA was originally formed specifically to foster the development, support, and adoption of RDMA and stands ready to continue doing so. Nothing about that has changed in our mission.<o:p></o:p></span></p>
