  • Proposal Regarding USENIX and Openfabrics Alliance Ellie Young, 9/18/2008
    Proposal Regarding USENIX and OpenFabrics Alliance Ellie Young, 9/18/2008 For the past two months a group from the OpenFabrics Alliance and USENIX management have been working together to reach an agreement on how best to explore the feasibility and desirability of OFA and USENIX combining forces in a way that would work to the advantage of both organizations. Now the USENIX Board must decide whether we should take the next step: sending a MOU to provide services to OFA as a 501(c)(6) under our 501(c)(3). We realized last week that in order for us to announce this at the obvious juncture, the upcoming Supercomputing Conference in November, we need to have a decision from OFA by September 29. In the past month USENIX has been given a consulting membership in OFA. Some of us have been participating in marketing, legal, and executive working group meetings. I think we have now spent enough time "getting to know one another." Background Last year, in response to the Board's request that we reach out to open source software projects and look beyond the academic and research community we currently serve, Clem Cole introduced us to several members of the OpenFabrics Alliance. We made a proposal to organize their annual Sonoma Workshop this past spring, but they decided to continue organizing this year’s event on their own. We were contacted again this summer. At a meeting in August, part of which Matt Blaze attended, we discussed the current state of OFA. Our notes on that meeting include: Software development: Development is the most valuable activity for OFA, but it's on its own track (Sonoma workshops, as well as workshops alongside Supercomputing, although there were none this year) and goes pretty smoothly for two software releases per year.
