The OpenFabrics Alliance (OFA) has updated the usage guidelines for its Remote Direct Memory Access (RDMA) training materials to encourage third party trainers to leverage and improve upon the OFA’s educational resources. With an aim toward strengthening the OFA’s educational efforts, the organization has decided to make these resources freely available for third party instructor use, with the understanding that any improvements made to the content be returned to the OFA for future consideration. This expands on the training materials’ existing purpose of individual education and instruction within organizations.

The RDMA training materials were created by the OFA and are available for free use under the GNU Free Documentation License terms. They are intended to provide professionals and organizations working in high performance computing and enterprise network industries with detailed information concerning RDMA verbs programming and resources to facilitate the mastering of coding concepts and techniques required to take advantage of RDMA.

The OFA training program is comprised of a suite of code examples and three presentations covering the following RDMA-themed topics:

  • An introduction to RDMA
  • Introduction on writing applications for RDMA
  • Conclusion on application programming for RDMA

Presentations and example suites can be downloaded from the OFA Training Files Downloads page.

More information on OFA RDMA training materials and terms of use can be found on the OFA Training Overview page.

The 13th Annual OpenFabrics Alliance Workshop is now in the books.  We’ll have more to say about the workshop in an upcoming blog. In the meantime, you can see all the presentations and videos here -

But for now, I want to concentrate on a significant change underway in how the OFA does business resulting in a new program of At Large Directors rolled out at the Workshop this year.

The OFA has always been an open source organization; the code produced by its members is freely available on public repositories and non-members are always welcome to participate in OFA working groups. The Board of Directors has also welcomed guidance from users and developers during our annual workshops and through participation in OFA working groups. Lately the OFA’s Board has looked for ways to strengthen its relationship with the broader community. One important step in that direction is the Board’s recent decision to create two new At Large Director positions on the Board. The objective is to bring outside voices into Board of Director discussions to ensure we are serving the entire open source community.

This notion of expanding the OFA’s outreach via an augmented Board was formally rolled out at the Workshop this year where nominations where held and two individuals were elected to serve a one year term as our first At Large Directors.

So, it is with great pleasure that the Board of Directors announce the election of Jason Gunthorpe and Bob Noseworthy as the first two holders of these At Large Director seats. Many of you know Jason; in addition to his long-time involvement with the OFA, he is a very active developer of RDMA solutions and widely respected within the Linux community. Bob Noseworthy describes himself as the Chief Sherpa at the University of New Hampshire Interoperability Lab (UNH-IOL) where he’s been immersed in the technology and engaged with its practitioners every day. These two outside voices are welcomed influences to the Board as we shape how the OFA will deliver on the emerging technologies that will be required by the next generation of data center.

Please join me in welcoming Jason and Bob and thanking them for taking on this important new role. I can say without a moments’ hesitation that we’re looking forward to this coming year.

Best Regards,

Week-Long Workshop Features Community-Wide Discussion on RDMA Technology and Future of OFA

The 13th Annual OpenFabrics Alliance (OFA) Workshop wrapped at the end of March with a look toward the future. The annual gathering, held this year in Austin, Texas, is devoted to advancing cutting edge networking technology through the ongoing collaborative efforts of OpenFabrics Software (OFS) producers and users. With a record 130+ attendees, the 2017 Workshop expanded on the OFA’s commitment to being an open organization by hosting an engaging Town Hall discussion and an At Large Board election, filling two newly added director seats for current members.

The personality of any well-designed organization naturally morphs over time. There are lots of reasons for this; in the case of the OpenFabrics Alliance (OFA) some of the key ones might be:

  • Growing adoption of RDMA by the computing community and what that means to the OFA
  • New or emerging fabrics
  • Galloping advances in technology
  • New usage models for computing systems

Recognizing that change is the status quo, the OFA Board has undertaken a review of our mission with an eye toward answering two deceptively simple questions: What should the Alliance look like and how should it behave in the years to come? What more can we do as an Alliance to add more value to the community of network developers and consumers?

Answering these questions requires a real dialog with Alliance members and with the broader networking community. To open that dialog, we’ve set aside some time at the upcoming Workshop for a Town Hall discussion. We’ll start by framing the question during Susan Coulter’s ‘State of the Alliance’ talk on Tuesday and continue it at the Town Hall discussion on Thursday.

Now comes the request; it is for you to do a bit of homework before the Workshop. The success of the Town Hall depends on a lively dialog, but that won’t happen unless we all spend a little time beforehand reflecting on the topic.  You can begin by asking yourself a few leading questions such as, “Strategically, why is the OFA important to my organization?” Or, “What value does my organization get from the Alliance?” Or even more importantly, “What value are we not receiving today?”

Obviously, in addressing these questions, no organization should reveal its strategic secrets. But with a moment’s reflection, and keeping in mind the goal of building a better, stronger Alliance, I’ll bet there are ways to share your insights, and even more importantly, your vision for the OpenFabrics Alliance going into the future. The key word here is ‘Alliance’.

Since not everybody has a clear view of the Alliance today, we’ll start on Tuesday with a kind of a framework to describe the OFA of today. Hopefully this will serve as a jumping off point to a lively conversation about the OFA of tomorrow.  

I hope you’re planning to attend the workshop. If you do, please come prepared to be an active participant in shaping the OFA’s future so it continues to meet the needs of the networking community. If you can’t make it to the workshop, please reach out to either me, or our Chair, Susan Coulter, to express your views directly. There’s always room for more ideas.

Kind regards,

Paul Grun
