Purposes of Meeting

Identify the possible list of features that are candidate items for development for Release 2.0 of the OpenFabrics Stack (note this is not an OFED candidate list);

Identify the developers/contributors/maintainers that are candidates to participate in the development team and their prerequisites before commitment to participate can be assured;

Recognize these developers as the “OF Release 2.0 Developers Working Group” (OF 2.0 DWG)

Allocate developer candidates to items agreed for development and “swag” timelines, engineering test procedures and other resources;

Identify Alliance member product managers and customers who will participate in the item prioritization and inclusion process (which also needs to be agreed)

Discuss and reach consensus on the agreed development item list, confirm responsible contributor/developer swagged timelines, level of engineering test and trunk commitment process

Discuss and agree with the Enterprise Working Group (who are responsible for OFED 1.x and 2.x) the OFED candidate deposition and SVN branching process for OFED 2.0

Review and agree bug identification, logging in Bugzilla, assigning to developer and bug resolution for both DWG and EWG


Attendance Criteria & Company Commitment

Meeting attendance is encouraged from OpenFabrics members and selected individuals that can contribute to the negotiation of and commitment to: 1) - the features and components of Release 2.0; 2) - the engineering processes and resources necessary to ensure that Release 2.0 is developed for hand-off to the EWG for OFED quality assurance; 3) – improving the OFED processes to assure that OFED 2.0 meets Enterprise quality and robustness criteria as well as HPC performance and feature requirements; 4) readiness for Interoperability testing.

Companies and members participating need to send developers and product managers that can commit (at the meeting) company resources, developer’s time and effort and regression test suites and systems that can engineering test OF 2.0 so that every company believes meet its customers needs with 2.0 after the EWG has put it thru OFED and drop their proprietary competing software stacks.

The paragraph above implies that companies must plan their participation and commitment in advance as well as interact with collaborating member companies to workout in advance a strawman division of feature commitment, responsibilities and resources.

Linux distros, ISVs Tier 1 and 2 OEMs and Customers who are invited to participate should also understand that they will be expected to participate in detailed technical implementation discussion and prioritization of features. Participation in this meeting is also an indication by the customer that significant testing will be done by qualified customer personnel utilizing significant customer resources sufficient to contribute to the enterprise readiness of OFED 2.0 when it is released
